A Comparison of HWRF, ARW and NMM Models in Hurricane Katrina (2005) Simulation
The life cycle of Hurricane Katrina (2005) was simulated using three different modeling systems of Weather Research and Forecasting (WRF) mesoscale model. These are, HWRF (Hurricane WRF) designed specifically for hurricane studies and WRF model with two different dynamic cores as the Advanced Research WRF (ARW) model and the Non-hydrostatic Mesoscale Model (NMM). The WRF model was developed and...
متن کاملComparison of Thunderstorm Simulations from WRF-NMM and WRF-ARW Models over East Indian Region
The thunderstorms are typical mesoscale systems dominated by intense convection. Mesoscale models are essential for the accurate prediction of such high-impact weather events. In the present study, an attempt has been made to compare the simulated results of three thunderstorm events using NMM and ARW model core of WRF system and validated the model results with observations. Both models perfor...
متن کاملP2B.10 Comparison and validation of WRF-ARW cloud microphysics schemes during C3VP/CLEX-10 field experiment
Better understanding of the vertical structures of clouds in the atmosphere is essential for more accurate radar, lidar, satellite retrievals, climate/weather numerical modeling, and even aviation safety issues regarding icing conditions (Fleishauer et al., 2002). However, an accurate estimate of liquid and ice phase hydrometeors in the clouds is still very challenging, and our limited knowledg...
متن کاملSimulation of rainfall temporal distribution pattern using WRF Model (case study of Parsian dam basin)
During the rainfall, the intensity of precipitation varies. Changes in the amount of precipitation during an event of rainfall are effective in the resulting of flood and its intensity. Knowledge of how rainfall changes over time during rainfall is determined by temporal distribution pattern of rainfall. For this purpose, availability of short-term time scales rainfalls data are important that ...
متن کاملPerformance Evaluation of Convective Parameterization Schemes of WRF-ARW Model in the Simulation of Pre-monsoon Thunderstorm Events over Kharagpur using STORM Data Sets
Thunderstorms associated with severe gusty winds and lightening cause loss of life and property even though they last for an hour or so. Forecasting of these severe weather events is highly essential due to their impact on socioeconomic conditions of affected regions. Kharagpur (22°30′ N, 87°20′ E) is in the region of Gangetic West Bengal (GWB) affected by high frequency of occurrence of thunde...
