2009; Mandal and Mohanty 2006; Sathi Devi et al. The improvements noticed can be attributed due to relatively better quality data that was specified for the initial mean position error (about 48 km) during 2013. The gradual improvements in the intensity and translation speed of the storm with the realistic representation of the OML are mainly due to the storm-induced cooling, which in turn alters the simulated enthalpy fluxes supplied to the TC, leading to the better representation of secondary circulation and the rapid intensification of the storm. 2004; Hari Prasad 2006, 2007; Bhaskar Rao et al. A high-resolution short-term model forecast initialized at 1800 UTC 2 August 1997 was made using the fifth-generation Pennsylvania State University-NCAR nonhydrostatic, two-way interactive, movable, triply nested grid Mesoscale Model (MM5). This study examines the role of parameterization of convection and Mean soundings for all regions from the eye through 12° radius are presented. to land surface changes such as the Tibetan snow depth, a sensitivity study has also been conducted. was found to increase the air–sea heat fluxes over the cyclonic region, which resulted in the improved a stronger cyclone in terms of minimum sea-level pressure and maximum wind speed. RMW with height and the position of the RMW relative to the inner cloud At least 13 million people, including 3.3 million children, 5 million women and nearly 3.5 million elderly people were affected in the nature’s fury. Three different cumulus A nonhydrostatic extension to the Pennsylvania State University-NCAR Mesoscale Model is presented, which employs reference pressure as the basis for a terrain-following vertical coordinate, and the fully compressible system of equations. TCs are accompanied by very strong winds, torrential rains and storm surges. The model's skill over a standard climatological/persistence forecast also improved dramatically. the associated rainfall is reduced by about 30% with the introduction of 10 cm of snow over the Tibetan region in the month A wind maximum is also found to the northeast of the vortex, which appears to be consistent with the observational findings of Shea and Gray. A tropical depression formed over the Malay Peninsula on October 25. All rights reserved. wind vectors. My memories of the 1999 Super Cyclone are like fleeting images of a kaleidoscope, some vivid and several hazy. observed SST over the Bay of Bengal are 1–2°C warmer than climatological SST, but cooler by nearly 1°C along the coastline. In the first one, called Control run, the National The storm circulation has very broad horizontal extent and appears to conform to a constant scale regardless of inner core intensity. The Indian subcontinent is the worst affected part of the world due to tropical cyclones (TCs). All rights reserved. are conducted in this study. In this paper, fore-cast of a severe precipitation event that occurred over the eastern central coast of Peninsular Malaysia was attempted using the state-of-the-art Florida State University (FSU) Global and Regional Spectral Models. In 1999, before the Super Cyclone struck, the Orissa had 21 shelters. The rainfall prediction is assessed qualitatively by comparing the spatial distribution with satellite A control run is presented, which shows good agreement with observations in many aspects. Since then, mean forecast errors have been considerably lower than mean statistics from recent years. In the first experiment the model is integrated with a synthetic vortex based on Rankine wind profile while in the second experiment we utilize the Holland wind profile. in the rain water formation in the simulated storm when compared to others within the group. It hit Bhubaneswar twice between 10 am to 12 noon and for a second time after a 30-minute gap. the second set utilizes the NCAR–AFWA synthetic vortex scheme. The Weather Research and Forecasting (WRF ARW) model was used to study the structure, evolution, and intensification The objective of this study is to investigate in detail the sensitivity of cumulus, planetary boundary layer and explicit resolution (5 km), the three-domain configuration (45-15-5 km The second simulation (FDDAALL) was performed with all the data of the Quick Scatterometer In 1999 the state experienced a super cyclone that claimed 15,000 lives. Storm Protection by Mangroves in Orissa: An Analysis of the 1999 Super Cyclone (SANDEE W orking Papers, ISSN 1893-1891; 2007- WP 25) ISBN: 978 - 9937 - 8015 - 5 - 3 A modified version of the typhoon bogus developed at the Japan Meteorological Agency has been installed in the Australian Bureau of Meteorology's tropical prediction system. have a natural asymmetry beyond that induced by storm motion; 9) The lack of information about the wind direction from SSM/I of a synthetic vortex based on Rankine as well as on Holland wind profiles, using NCAR-AFWA bogussing scheme for the prediction the intensity and location of mesoscale heavy rainfall, as well as in the intensity and path of the super-cyclone, are found. The categorical forecast skill also reveals that although the accuracy of the model is high for 2002, but the probability of detection of extreme events are higher for 1997. Mesoscale Model (MM5) with three-dimensional variational data assimilation (3DVAR) is utilized Orissa 1999 Stock Photos and Images (60) Page 1 of 1. The model performances are compared by examining the predicted parameters like mean sea level pressure, wind, moisture It appears that combined effect of midlatitude trough interaction, strength of the anticyclone simulations. updated Kain Fritsch (KF2), are tested. A boundary layer diffusion package based on the Troen and Mahrt nonlocal diffusion concept has been tested for possible operational implementation. The model simulations have been conducted with different initial conditions to know the effective track and intensity prediction of JAL cyclone. Locals for whom formation of low pressure, depression weather and storm has become a periodic feature are on the alert to face exigencies of the situation. The use of the different schemes produced different results of precipitation features such as the intensification of mon - soon depressions ( Vaidya et al . to capture the trend in the observed data, the computed results deviate from observations. The Super Cyclone was preceded by another on October 17 which had affected southern Odisha and, people thinking that the worst was over were not … While the lowest central pressure estimated from the satellite image is 988 hPa, overestimated by Sc. After merging the specified vortex with the environmental flow, the mass field is diagnosed from the divergence equation with an appropriately controlled time tendency. While the first set utilizes the National Center for Environmental Prediction (NCEP) reanalysis (for the initial and lateral boundary conditions) only in the fifth-generation mesoscale model simulation, the second set utilized the AMSU satellite and conventional meteorological upper air and surface data to provide an improved analysis through analysis nudging. The initial and boundary conditions for this study have been taken from NCEP FNL analysis data available at 1° resolution. (1) unprecedented locally heavy rainfall near Mumbai (Santa Cruz) on 26 and 27 July 2005 and (2) the Orissa super-cyclone as heavy monsoon rainfall, tropical cyclone genesis and movement and severe local thunderstorms, as the processes controlling In the proposed method, a crudely resolved tropical cyclone in the large-scale analysis is replaced by a vortex that is properly specified for use in the prediction model. remaining experiments available observations were used to obtain an improved analysis and FDDA grid nudging was performed The NSM with a modest treatment The extent of the damage is difficult to determine. The nested 2D and 3D experiments produce cyclone track closely agreeing with the observations, while the 1D experiments show the deviation of the track toward north and northeast after 48 h, thus with increasing errors. In order to provide an adequate number of case studies for a good statistical sample, the present study is extended for three additional cyclones over the Indian region. Schultz (Sc), are tested in these experiments. The dynamic control is the part that determines the modulation of the convection by the environment. The initialization scheme designed at GFDL to specify a more realistic initial storm structure of tropical cyclones was tested on four real data cases using the GFDL high-resolution multiply nested movable mesh hurricane model. A radiative upper boundary condition is proposed for numerical mesoscale models which allows vertically propagating internal gravity waves to pass out of the computational domain with minimal reflection. This region account for ~7 % 0.of the total number of global TCs (Gray 1968). schematic model of the flow conditions in the inner hurricane core is Study on super cyclone in Orissa 1999 with special reference to early warning system. In order to test the model response Photocopy from microfilm. ii) Melting and evaporation contribute to a localized mesoscale subsidence in a 50 km region to the rear of the moving convective area. It is the spiral arrangement of thunderstorms rains, a low-pressure center, and strong winds. On 17-18 October 1999, 5 districts of the State of Orissa in India were hit by a cyclone, and on 29 October another, exceptionally strong cyclone (“supercyclone”) devastated a large portion of the State. The model simulated Indian summer monsoon circulation becomes weaker and The Betts-Miller-Janjic convection scheme produced A particular feature of the paper is the series of synoptic studies of the four waves which gave rise to named storms (Danny, Elena, Fabian, and Gloria) during the period. The results from this approach are compared with those from the local diffusion approach, which is the current operational scheme, and verified against FIFE observations during 9-10 August 1987. cyclone intensity. research and operational usage. 2(a-d). Mighty waves are crashing the shorelines. parameterization schemes, namely Grell (Gr), Betts-Miller (BM) and the corresponding value in the synthetic vortex simulated cyclone is 993 hPa. features are discussed.Many significant features are noted: 1) storm phase. Hurricane Inez is described here in a very small, intense state and, as such, deserves its own place in the hierarchy of models. A composite study of 10 years of northwest Pacific rawinsonde data is used to analyze the large-scale structure of tropical cyclones. (Photo: SNS). (FDDA) technique. presented. Accurate prediction of monsoon heavy rainfall events in the equatorial region has always been a challenge to weather forecasters. Journal of Applied Meteorology and Climatology. surface parameterizations in the fifth-generation Pennsylvania State University-National Center for Atmospheric Research (PSU-NCAR) However, for the November 2002 cyclone there were no significant differences in the spatial distribution of precipitation for both the experiments. You can request the full-text of this article directly from the authors on ResearchGate. The tropical cyclones form over the oceanic regions where conventional meteorological observations are not available. Budgets constructed for this layer suggested (when taken with other data) a nonlinear relationship between the drag coefficient and the wind speed, moisture convergence in the inflow layer led to postulated rainfall rates ranging from 0.15 in h−1 in the 40 to 50 n mi annulus to 1.9 in h−1 in the 0 to 10 n mi circle. “The 1999 Odisha super cyclone has taught us the lesson not to ignore weather warning. In the control run (CONTROL), the WRF model is initialized without coupling. The ERA-Interim reanalysis data are used to drive the model and the India Meteorological Department (IMD) and modern-era retrospective analysis for research and applications (MERRA) rainfall data are used for precipitation verification. A super-cyclone in 1999 killed more than 10,000 people in Orissa. that proper selection of synthetic vortex, initialization scheme and resolution of the model are very important for better From the results, influence of cumulus convection on steering An attempt is made to document the radar observed features of evolution of super cyclone that hit Orissa on 29 October, 1999. Rainfall and other predicted parameters are discussed on the basis of known Bengal cyclones. Super Cyclone Amphan became the strongest storm ever recorded in the Bay of Bengal on May 18, after intensifying with sustained wind speeds of up to 270 kilometers per hour (165 miles per hours). The track and intensity of the storm is better simulated with the use of satellite-observed SST. We also note a good correlation between evolution of frozen condensate and storm intensification rate among Two sets of numerical experiments are designed in this study. QSCAT weather disturbances over the Indian region. Mausam 48: 351-366. distribution. disasters. Three of the test cases involved Hurricane Gloria (1985) in the Atlantic basin; the fourth involved Hurricane Gilbert (1988) in the Gulf of Mexico. Indian summer monsoon circulation including the monsoon rainfall has been simulated with the regional climate model (RegCM3) for two different years associating an ENSO and a drought year. and maximum wind speed reveal that the model simulations are closer to observations when synthetic vortex was introduced in These TCs have been responsible for the damage of property, loss of agriculture crops, and thousands of human lives (Paul 2010). for both the domains (D1 and D2). “The 1999 Odisha super cyclone has taught us the lesson not to ignore weather warning. The scope of the present study is to understand the impact of the cumulus parameterization schemes and cloud microphysics parameterization schemes on the simulation of track, intensity and structure of the Orissa super cyclone (OSC-99) in the north Indian Ocean. The track error of the cyclone for the November 2002 cyclone is less in the model simulation with the Holland vortex at the initial time and at 24 hours of forecast. (MP), Goddard microphysics with Graupel (GG), Reisner Graupel (RG) and sensitivity of model simulation/forecast to SST, it is not well quantified, particularly for Bay of showed greater vertical wind speed as compared to the Holland vortex. Model. The fourth set contains initial condition sensitivity experiments. INDIA: ORISSA CYCLONE 30 October 2001 The context A violent cyclone hit India’s eastern coast on Friday, 29 October 1999. Yet, differences are appreciably marked. This decrease of moisture in the TPW assimilation experiment resulted in a weak Thesis--University of Pennsylvania. has resulted in improvements in the simulation of wind asymmetries, warm temperature anomalies, stronger vertical velocity We are tuned to hourly radio updates of AIR Cuttack. Simply super cyclones are tropical storms, where wind speeds cross 220kmph (137mph). One way of overcoming the above difficulty is to remove the weak initial A spectral decomposition further reveals that (i) large differences between the model simulation and radar analysis of the asymmetric features are mostly caused by azimuthal phase errors; (ii) the wavenumber 1 component dominates the asymmetric features and remains stationary within the inner core region, as is also observed by airborne Doppler radar; and (iii) although being significantly different from radar analysis, the azimuthal phase of the wavenumber 1 component of modeled reflectivity does not vary greatly with time as the radar data suggest. storm. The formation of TCs is more pronounced over Bay of Bengal (BOB) compared to Arabian Sea. sensitivity runs latitude, maximum wind, inner radar radius, central pressure, and other performed marginally better than the one with SSM/I winds due to better representation of surface wind vectors. People are steadily shifting to the safety of cyclone shelters”, narrated Bijoy Shukla, an ex-sarpanch of seaside Ramnagar gram panchayat in Kendrapara district, on Friday. India Meteorological Department (IMD). Life cycle of this su­ per cyclonic storm from its genesis to landfall is studied using IRS-P4 satellite derived parameters over the oceanic region. This contributes to a poor initial analysis of the cyclonic vortex and hence inadequate forecast. cyclones. The model has been simulated for the period June–August for 1997 and 2002, of which 1997 was an ENSO year and 2002 was a drought year. during mature/dissipation stage of thunderstorm. prevented it from making much of an impact on track prediction. The intensity of the cyclone is well simulated by YSU scheme and it depends upon the mixing treatment in and above PBL. Results of the sensitivity tests are compared to observations in terms of sea level pressure, rainfall patterns, and domain-averaged bias errors (compared to the control run) of various properties. It is found that the Rankine vortex and Holland’s vortex show the best representation of cyclonic circulation. It is shown that the method of diabatic nudging used for assimilation and initialization in the Australian tropical model is quite effective in reducing the impact of these problems. In this study NCAR MM5 with the cumulus parameterization scheme of Kain-Fritsch is used to simulate the evaluation of Orissa Super Cyclone for the period 25-30 October 1999. Synthetic temperature and humidity data are also The QLM forecasts of landfall compare well with the NHC83, but over the open oceans, where observations are sparse, the NHC83 performs better than the QLM. Three numerical experiments are conducted with 1] The prediction of the intensification and movement of the Orissa Super Cyclone (OSC-1999) was studied using the National Center for Atmospheric Research MM5 mesoscale atmospheric model. station values reported in Indian Daily Weather Reports. and the simulated rainfall is validated against observations from the Global Precipitation Climatology Centre (GPCC) and the -from Authors. The FDDAALL The results indicate that the CONTROL exhibits an early intensification phase with a faster translation movement, leading to early landfall and the production of large track deviations. The prediction of the intensification and movement of the Orissa Super Cyclone (OSC-1999) was studied using the National Center for Atmospheric Research MM5 mesoscale atmospheric model. Sea during May 2004, using the MM5 model. What is a super cyclone? -from Authors. The present study is unique in the sense that it addresses the impact of ingesting and assimilating microwave sounding data ( together with conventional India Meteorological Department data) on the prediction of a tropical cyclone, which formed over the Arabian Sea during November 2003 using analysis nudging. The predicted mean track error during 2013 was about 71 km, 114 km, 133 km, 148 km, and 130 km respectively from day-1 to day-5. observed heavy precipitation rates. “The 1999 Odisha super cyclone has taught us the lesson not to ignore weather warning. In this study NCAR MM5 with the cumulus parameterization scheme of Kain-Fritsch is used to simulate the evaluation of Orissa Super Cyclone for the period 25-30 October 1999. The area is almost impossible to reach, as the cyclone has torn down bridges and made roads and railways impassable. The results of the study for the November 2002 cyclone show that the model simulation with the Holland vortex has produced studies confirmed the, In this study, the fifth-generation Pennsylvania State University–National Center for Atmospheric Research It is found that the forecast track and intensity of the cyclone are most sensitive All four cyclones studied here show that the Holland vortex has produced a stronger cyclone in terms of the minimum sea-level pressure and maximum wind speed. pattern closely agreeing with the analysis. Based on the current storm motion, the dipole imposes a steering current on the vortex. (b) The cloud spirals tighten and concentrate convection. Experiments were made with a single domain (1D), with two-way interactive nested two domains (2D), and with three domains (3D). core structure of Orissa super cyclone (1999) in Bay of Bengal (north flow of the cyclone is evident. The sensitivity of the simulated tropical cyclone (TC) intensity and tracks to the different ocean mixed-layer depth (MLD) initializations is studied using coupled weather research and forecasting (WRF) and ocean mixed-layer (OML) models. It was also known as Cyclone 05B. Like QuikSCAT, assimilation of SSM/I wind speeds strengthened the cyclonic circulation in the initial two vortices are used in the sensitivity studies to simulate two cyclones, one of May 1979 and the other of August 1979. The construction of the bogus vortex is described and the impact on forecasts during several tropical cyclone events is illustrated. A comparative study has been carried out using two cumulus parameterization schemes, namely the Kain-Fritsch and Betts-Miller-Janjic indicate that the sea surface temperature has a significant impact on model-simulated track and intensity of the cyclonic The coupled OML simulations captured the deepening phase close to the observed estimates, resulting in the reduction of errors in both the vector and along the tracks of the storm. Orissa cyclone in pictures: Wednesday, November 3, 1999 : weather spotlight today's calendar: The following are PTI photographs of the devastation caused by the cyclone in coastal Orissa. e9 = new Object(); (QSCAT), Special Sensor Microwave Imager (SSM/I) winds, conventional surface, and upper air meteorological observations. Satellite image of cyclone Phailin at 5.30 p.m. on October 12. Odisha’s super cyclone is etched vividly in the minds of everyone who has experienced it. The objective of the present study is to examine the impact of satellite derived winds in improving model initial condition and hence in mesoscale simulation of cyclonic storm. The PBL group of experiments has less influence on the track forecast of the cyclone compared to CPS. Precaution has become the prime concern for people as cyclone wrought devastation scripted in theses villages two decades ago trail back to worry them. enhances by 17 m s −1 with the introduction of the synthetic vortex.

downplayed the horrendous impact on the lives of the people. Advanced Regional Prediction System Model has well predicted the spatial distribution of rainfall which is consistent with Where all did extreme events cause disasters last decade . This paper describes a typhoon track prediction model under development at JMA and its forecast performance using observed data for a limited sample of cyclones. The modeled Guillermo followed the observed track with less than a 12-km track error at any time during the 6-h forecast period. Detailed analysis showed that, with the incorporation of observed local vegetation climatological SST, NCEP (National Center for Environmental Prediction) skin temperature as SST, and observed SST (satellite Further, the dependency of intensity of cyclone has been studied in terms of surface latent heat flux, divergence and vorticity fields. the center than in weaker storms; 11) faster moving storms were more Whenever there is forecast of depression and stormy weather, seagoing fishermen have been staying away from fishing voyage. SCAT) observations on the prediction of an Indian Ocean tropical cyclone. Orissa Super Cyclone: Update on UNICEF Activities since Oct 1999. The objective of this study is to investigate the impact of ingesting and assimilating the AMSU data together with conventional upper air and surface meteorological observations over India on the prediction of a tropical cyclone which formed over the Arabian Sea during November 2003 using analysis nudging. An east-west asymmetry in the meridional wind field is also created. It is shown that this model, combined with the existing initialization techniques and the physics of the current hydrostatic model, is capable of real-data simulations on any scale, limited only by data quality and resolution and by computer resources. The specified vortex consists of both axisymmetric and asymmetric components. wind, temperature/moisture fields and rainfall. The results are evaluated using predicted parameters such as mean sea level pressure, Centers for Environmental Prediction (NCEP) Final Analysis (FNL) was used for the initial and boundary conditions. The model simulation produces the development of the Orissa Super Cyclone with attained central sea level pressure of 954 hPa and maximum wind of 58 msec-1. position error of 33 km, which was 163 km in the background analysis. Read More . tropical cyclone tracks and intensity variation have considerable The intensity is well predicted when no CPS is used in the Storms are stratified by deepening and filling tendency, Further evaluation of the predictive skills showed that the Relaxed Arakawa-Schubert scheme was a consistently better predictor of rainfall due to its low bias and lower root mean square errors (RMSEs) compared to the modified Kuo parameterization scheme. This northwestward movement increases with both the maximum wind speed and the radius of maximum wind in a constant-shape vortex. Charge your mobiles and use it sparingly. The present study comprises two major components. super cyclone hit Orissa on 29th October, 1999. Winds of up to 260kph (155 mph) raged for over 36 hours. The wind field remains unchanged at this step of initialization. vortex and replace it with a synthetic vortex (with the correct size, intensity and location) in the initial analysis. This is probably because of the better representation of large-scale monsoon features, such as a monsoon trough in the HY36 and local-scale convective activities in the NH12. The 1999 Super Cyclone possesses a ghastly record when it comes to casualty figures. This asymmetry plays an important role in the vortex motion. storm core due to the absence of melting process and reduction of water loading in the model due to absence of frozen hydrometeors Appropriate filters are used to remove the vortex from the large-scale analysis so that a smooth environmental field remains. The NCAR MM5 with two-way nested horizontal domains of 90, 30 and 10 km are integrated for five days starting from 0000 UTC of 25 October, 1999. All severe land-falling Bay of Bengal cyclones during the five-year period 1995–1999 are simulated to evaluate the performance of the modeling system in this basin.
