Summary: The main model that forecasters use to predict what a hurricane will do is the Hurricane Weather Research and Forecast (HWRF) model. Because we cannot measure what is currently happening in the hurricane exactly, we run the model many times at once with different measurements to get an idea of the different forecasts that …

Paper on the rapid intensification of Hurricane Earl published in the Journal of the Atmospheric Sciences
Hurricanes sometimes change intensity very quickly, and if this happens when they approach land, it can suddenly cause a lot of damage or kill many people. This so-called Rapid Intensification (RI) is very hard to forecast. For the first time, the Hurricane Weather Research and Forecast (HWRF) model that NOAA uses to forecast where a …
