Improving the prediction of weather events is always an important research area and challenging task to meteorologists since it poses a major impact on human life, properties countries economy. The operational centers around globe have been working better understand multiscale interactions involved advance severe including Tropical Cyclones thunderstorm predictions. present review article focuses activities with specific emphasis Numerical Weather Prediction (NWP) methods that led...
An attempt is made to delineate the relative performances and credentials of GFS, FNL, NCMRWF global analyses/forecast products as initial boundary conditions (IBCs) WRF-ARW model in simulation four Bay Bengal tropical cyclones (TCs). The results suggest that FNL could simulate horizontal advection vorticity maxima at 850 hPa; hence, tracks are more realistic with least errors compared GFS NCMRWF. mean landfall for 24-, 48-, 72-hour forecasts 73, 41, 72 km, respectively. TC intensity well...
In the present satellite era, remote-sensing data are more useful to improve initial condition of model and hence forecast tropical cyclones (TCs) when they in deep oceans, where conventional observations unavailable. this study, an attempt is made assess impact remotely sensed satellite-derived winds on initialization simulation TCs over North Indian Ocean (NIO). For purpose, four TCs, namely, 'Nargis', 'Gonu', 'Sidr' 'KhaiMuk', considered, with 13 different conditions. Two sets numerical...
This article describes a unique field experiment on Severe Thunderstorm Observations and Regional Modeling (STORM) jointly undertaken by eight South Asian countries. Several pilot experiments have been conducted so far, the results are analyzed. The will continue through 2016. STORM program was originally conceived for understanding severe thunderstorms known as nor'westers that affect West Bengal northeastern parts of India during pre-monsoon season. cause loss human lives damage to...
Abstract North Indian Ocean (NIO), which comprises of Bay Bengal (BoB) and Arabian Sea (AS) basins, is one the highly potential regions for Tropical Cyclones (TCs) in world. Significant improvements have been achieved prediction movement TCs, since last decade. However, sudden intensity changes becomes a challenging task research operational meteorologists. Hence, present study focuses on finding climatological characteristics such over NIO regions. Rapid Intensification (RI) defined as 24-h...
The present study is carried out to investigate the performance of different cumulus convection, planetary boundary layer, land surface processes, and microphysics parameterization schemes in simulation a very severe cyclonic storm (VSCS) Nargis (2008), developed central Bay Bengal on 27 April 2008. For this purpose, nonhydrostatic mesoscale model (NMM) dynamic core weather research forecasting (WRF) system used. Model-simulated track positions intensity terms minimum mean sea level pressure...
Improving the Tropical cyclone (TC) prediction is always an important research area and challenging task to meteorologists since it poses a major impact on human life, properties countries economy.The operational centers around globe have been working better understand multiscale interactions involved advance TC predictions.Mohanty Gupta (1997) elaborated different statistical dynamical methods for track of TCs over North Indian Ocean (NIO) basin.The present review article focuses activities...
Abstract Urbanization alters local climates and exacerbates urban heat islands. Understanding addressing the impacts of urbanization on regional high impact weather systems is critical. This study examines feedback loop between heatwaves (HWs) in inland coastal Indian cities Hyderabad Bhubaneswar which have been profoundly affected by temperature extremes. Observational analysis reveals that during pre‐monsoon season, daytime nighttime air anomalies, frequency 90th percentile days, increased...
The thunderstorms are typical mesoscale systems dominated by intense convection. Mesoscale models essential for the accurate prediction of such high-impact weather events. In present study, an attempt has been made to compare simulated results three thunderstorm events using NMM and ARW model core WRF system validated with observations. Both performed well in capturing stability indices which indicators severe convective activity. Comparison model-simulated radar reflectivity imageries...
