A comparison of HWRF, ARW and NMM models in Hurricane Katrina (2005) simulation. [PDF]
Int J Environ Res Public Health, 2011 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 ...
