Secondly, the study also investigated the model performance based on the best possible combinations of model physics on the real-time forecasts of four BoB cyclones (Phailin, Helen, Lehar, and Madi) that made landfall during 2013 based on another 15 numerical simulations. Sea during May 2004, using the MM5 model. The main objective of the study is to improve model initialization and evaluate the model performance towards prediction of intensity, track, and landfall of these storms. performed marginally better than the one with SSM/I winds due to better representation of surface wind vectors. 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. or are analyzed very poorly, with ill defined centres and locations. Prediction of track and intensity of tropical cyclones is one of the most challenging problems in numerical weather prediction (NWP). ... Krishnamurty et al. Only one assumption at a time is changed and tested using a midlatitude environment of severe convection. weather disturbances over the Indian region. The The track error of the cyclone for the November 2002 cyclone is less in the model simulation with the Holland station values reported in Indian Daily Weather Reports. KeywordsTropical cyclones-Physical processes-Parameterization schemes-Mesoscale model-Super cyclone Gonu (2007). Finally, results from MPS set simulations. Such studies are important as most weather systems over India form over the seas. The early warning is a major component and it includes skill in monitoring and prediction of cyclone, effective warning products generation and dissemination, coordination with emergency response units and the public perception about the credibility of the official predictions and warnings. except over the central region of the cyclone, where the assimilation of SSM/I TPW reduces the lowertropospheric It has rich mineral resources like bauxite, iron-ore, manganese-ore, limestone, The 1999 Super Cyclone has been the biggest reference point- it has passed, but its lessons and memories have remained. This study evaluates the performance of the Advanced Research Weather Research and Forecasting (WRF-ARW) model for prediction of land-falling Bay of Bengal (BoB) tropical cyclones (TCs). 2010; Mohapatra et al. The objective of this study is to examine the impact of assimilation of conventional and satellite data on the prediction of the storm. A composite study of 10 years of northwest Pacific rawinsonde data is used to analyze the large-scale structure of tropical cyclones. The present study comprises two major components. these experiments.

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 essential characteristics such as warm core, eye and eye-wall simulation, hurricane core winds were obtained by the model. When it failed to do so, the alert was discontinued. A day after Cyclone Phailin made landfall in the Indian state or Orissa a man travels to work through devastated streets. It is shown that the method of initialization can have a large effect on the imposed structure and can affect the quality of prediction of both the tropical cyclone itself and the large scale flows quite remote from the storm center. High-impact mesoscale weather events, occurring in different parts of India in all seasons, lead to major weather- and climate-related Rainfall characteristics of the area inside 4° radius are discussed. KALSI : ORISSA SUPER CYCLONE – A SYNOPSIS 3 Figs. 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. It also has simulated the diverging winds at lower levels associated with downdraft In this study we are investigating the effect of inclusion of a synthetic vortex based on Rankine as well as on Holland wind profiles, using NCAR-AFWA bogussing scheme for the prediction of four tropical cyclones, which formed over the Bay of Bengal during November 2002 and 2005, December 2005 and over the Arabian Sea during May 2004, using the MM5 model. observed SST over the Bay of Bengal are 1–2°C warmer than climatological SST, but cooler by nearly 1°C along the coastline. 2012, 2015). People of the state capital Bhubaneswar as well as the coastal villages of Puri, Jagatsinghpur, Cuttack and Kendrapara districts who faced the wrath of the extremely severe Cyclone Fani on Friday were drawing comparisons with the devastation caused by the 1999 Odisha Super Cyclone. In addition, the resolution was increased substantially to a triangular truncation at T106. For the residents of Bhubaneswar, Fani was similar to the super cyclone in many ways as it caused havoc for almost three hours. Detailed analysis showed that, with the incorporation of observed local vegetation intensity both are very sensitive to CPS and comparatively, KF2 predicts 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 sensitivity of parameterized convection in these models on precipitation forecast skill is studied using two different parameterization schemes for cumulus convection (the Relaxed Arakawa-Schubert scheme and the modified Kuo scheme). Three of the test cases involved Hurricane Gloria (1985) in the Atlantic basin; the fourth involved Hurricane Gilbert (1988) in the Gulf of Mexico. prevented it from making much of an impact on track prediction. The most crucial ones were downdrafts and lateral mixing. disasters. The model has been simulated with numerous experiments using the logical/scientific combination of convection and micro-physics schemes. 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. This second cyclone caused severe damage in 14 of the 30 districts of Orissa (5 being hit for the second time (See map 1). Approximately 275,000 homes were destroyed leaving 1.67 … Simply super cyclones are tropical storms, where wind speeds cross 220kmph (137mph). Photocopy from microfilm. Rains have begun to lash our village. The average errors in track forecast in the present study are compared with the average error in representing the tracks in the National Center for Environmental Prediction (NCEP) reanalysis, errors in similar other predictions, operational prediction, and forecast difficulty level (FDL) in North Indian Basin. Particularly, the rapid intensification phase of A control run is presented, which shows good agreement with observations in many aspects.

Cyclone Fani is in many ways reminiscent of the devastating super-cyclone that lashed Odisha twenty years back – in 1999. examine the impact from microphysics parameterization schemes (MPS). Utilizing these results, an idealized, steady-state Memorandum on Damages caused by the Super Cyclonic Storm of Rarest Severity in the State of Odisha on 29th-30th October, 1999. However, for the November 2002 cyclone there were no Like QuikSCAT, assimilation of SSM/I wind speeds strengthened the cyclonic circulation in the initial Three sets of sensitivity While the first set utilizes the NCEP reanalysis as the initial and lateral boundary conditions, Published on 13 Jan 2000. Some statistical results pertaining to all four cyclones are provided such as the average track error as well as the average difference between the observed and the model minimum sea-level pressure and the maximum wind speed. The initialization of the different estimates of the MLD in the WRF-OML shows that the TC intensity and translation speed are sensitive to the initial representation of the MLD for the post-monsoon storm. Report. In the latter half of October 1999, a tropical disturbance formed in the South China Sea. The Orissa Super Cyclone 1999 Asian Disaster Reduction Center Report on Recovery and Reconstruction Following the Orissa Super Cyclone in October 1999 Anil Kkumar Sinha Senior Technical Advisor, Asian Disaster Reduction Center Orissa witnessed a series of major natural disasters in 1999… Incorporation of QuikSCAT winds has resulted in improvements in the simulation of wind asymmetries, warm temperature anomalies, stronger vertical velocity We also note a good correlation between evolution of frozen condensate and storm intensification rate among The comparisons between local and nonlocal approaches are extended to the forecast for a heavy rain case of 15-17 May 1995. QSCAT You can request the full-text of this article directly from the authors on ResearchGate. The two preceding articles, LeSeur and Hawkins (1963), and Hawkins and Rubsam (1968), dealt with a weak and a moderate hurricane (respectively). Over central India, the HY36 performs better followed by the NH12; and the contrasting precipitation features are also well depicted in the HY36 and NH12. The model utilizes a limited area grid and is nested in a one-way sense to the forecasts of a hemispheric model. Two numerical experiments are designed in this study for each of the above four of the cyclone. 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. Higher net heating in the middle level enhances the divergence in the upper level and convergence in the lower level which in turn helps in the intensification of the system. Where all did extreme events cause disasters last decade . Concentration of frozen hydrometeors, such as graupel in WSM6 MP scheme and latent heat released during auto conversion of hydrometeors may be responsible for storm intensity. The NSM with a modest treatment It is found that in case of idealized simulation of thunderstorm, On October 29 (Friday) 1999, a super cyclonic storm hit the coastal districts of Orissa like Kendrapara, Jagatsinghpur, Jajpur, Bhadrak, some parts of Puri and Khurda and adjacent areas along the Bay of Bengal with a velocity of more than 300 kmph. intensity and storm speed. for a pre-forecast period of 24h. 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. “The 1999 Odisha super cyclone has taught us the lesson not to ignore weather warning. Subsequently, a 19-day trial of the new scheme running in parallel with the old scheme was undertaken. found that the coupling of the NSM with the Troen-Mahrt ABL scheme leads to excessive ABL mixing and a dry bias in the model For the fourth experiment (MLD-DENS), the model is initialized with the density-based MLD obtained from ARMOR-3D data. Office has initialised tropical cyclones (TCs) in its global model by use of ‘bogus’ observations representing a simple symmetric vortex. showed greater vertical wind speed as compared to the Holland vortex. Using the new scheme, the average 24-h and 48-h forecast error for the four test cases was 58 and 94 km, respectively, compared with 143 and 191 km for the noninitialized forecasts starting from the global analysis. However, the convection schemes lacked skill in predicting the correct placement of the area and amount for the high precipitation threshold greater than 40 mm day –1 . The vortex initialization in the model is done through 12 hours nudging to the prepared high-resolution reanalysis. experiment, NIMBUS-7 SMMR snow depth data in spring are used as initial conditions in the RegCM3. The MPS of MP and Sc could very well capture the rapid intensification 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. K E Y W O R D S hydrostatic core, Indian summer monsoon, non-hydrostatic core, RegCM. Improvements in prediction are obtained in nearly all cases. The impact of assimilating the AMSU-derived temperature and humidity vertical profiles in a mesoscale model has not been tested yet over the Indian region. All four cyclones studied here show that the Holland vortex has produced a stronger cyclone in terms of the The present study is designed to quantify the sensitivity of SST on mesoscale simulation of an explosively We find that the important monsoon circulation features are well simulated by the model including the low mean seasonal rainfall of 2002 over India. Because analysis of the cyclone's circulation was inadequate in the initial fields owing to the coarse resolution of the operational analysis systems and sparse oceanic data coverage, synthetic vortex data were generated using empirical relations and used in the analysis. symmetric storm and a five-level mean asymmetric storm. Winds of up to 260kph (155 mph) raged for over 36 hours. At model initial state, NCEP skin temperature and People had thrown caution to the winds and had exposed themselves to the marauding tidal waves. The reduction of cyclone disasters depends on several factors including hazard analysis, vulnerability analysis, preparedness and planning, early warning, prevention and mitigation. integrated from 10 November 2002 18 UTC to 12 November, 2002 12 UTC with the synthetic vortex inserted at the initial time. Observed SST shows a number of warm patches in the Bay of Bengal compared with NCEP skin temperature. Based on the current storm motion, the dipole imposes a steering current on the vortex. Hence, there is a need to improve the understanding and the forecast of TC over the Indian Ocean region. 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. diabatic initialization of the mass and velocity fields and the forecasts of both the vortices behave differently. As I cover Cyclone Phailin in 2013, I cannot help remember the super-cyclone of 1999. RMW with height and the position of the RMW relative to the inner cloud The model produces a very good estimate of track with errors of 120 km at 24 hours and decreasing to 0 km at 120 hours. The construction of the bogus vortex is described and the impact on forecasts during several tropical cyclone events is illustrated. In addition, the effect of cumulus parameterization schemes at different resolution (27 and 9 km) on the cyclone track and intensity is reported. impact of cumulus parameterization schemes (CPS) using MM5 model 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. Their study reports a good simulation of the Orissa super cyclone but with an underestimate of cyclone intensity. surface pressure and rainfall simulated by the model over the Indian region are examined for two convective schemes (a Kuo-type 0600 UTC VIS images from 26-29 October 1999 showing development of Orissa Super TC. In this study, the nonhydrostatic version of Pennsylvania State University (PSU)/National Center for Atmospheric Research (NCAR) mesoscale model MM5 is used to simulate the severe land-falling Bay of Bengal cyclones. examine the effect of the cumulus parameterization scheme at high Results indicate that the enhancement of resolution produces higher intensity and does not influence the track of the storm. A case study of the OSC has been chosen as it is noted to be the most intense cyclone over the Bay of Bengal of this century. wind vectors. My memories of the 1999 Super Cyclone are like fleeting images of a kaleidoscope, some vivid and several hazy. What is a super cyclone? Effect of initial condition from different data sources on the numerical simulation of Orissa Super Cyclone is studied by. and the maximum wind speed. cyclone track forecast. The statistical results corresponding to the average of all the four cyclones are at only a slight The Betts-Miller-Janjic convection scheme produced 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. Copyright © 2020 The Statesman Limited. A tropical depression formed over the Malay Peninsula on October 25. The lack of information about the wind direction from SSM/I smoother and more convective rainfall rates in all cases. Appropriate filters are used to remove the vortex from the large-scale analysis so that a smooth environmental field remains. Integrated moisture convergence leads to underprediction of rainfall rates and subsequent degrading of the results in terms of movement and structure of the mesoscale convective system (MCS).
