- Abstract
The article presents a study to improve the capability of hurricane intensity and structure forecasts by radar data assimilation using the landfall data of Hurricane Isabel in the U.S. on September 18, 2003. It says that tropical cyclone (TC) track improves well over the past years, but TC intensity forecasts have been recorded for its errors. This study will prove that the use of land-based Doppler radar observations in a mesoscale numerical weather prediction (NWP) model can improve TC intensity forecasts. An overview of the landfall data of hurricane Isabel is offered, along with the conducted radar observations. Meanwhile, the study finds out that the use of radar data assimilation has a potential for improving hurricane intensity and structure forecasts.
