Abstract:

Large eddy simulations (LESs) of Hurricane Isaac using Weather Research and Forecasting (WRF) model forced by the sea surface temperature (SST) from Unified Wave INterface - Coupled Model (UWIN-CM)that includes the storm-induced SST cooling and by the SST from NCEP FNL analysis without the storm-induced SST cooling. The data includes meteorological variables and hydrometeor mixing ratio at the horizontal resolution of 74 m from 23:00 UTC, 08-27-2012 to 12:00 UTC, 08-28-2012.
