We studied how Hurricane Hunter aircraft observations can improve tropical cyclones forecasts from the National Oceanic and Atmospheric Administration's Hurricane Weather Research and Forecast (HWRF) model. Important Conclusions: Hurricane Hunter aircraft data generally improve HWRF forecasts. These improved forecasts are mainly in weak storms, since, without the data, HWRF often forecast storms that are too … Continue reading Paper on the impact of using Hurricane Hunter data in the HWRF model published in Monthly Weather Review
Summary: Though tropical cyclones (TCs) are usually hundreds of miles across, the strongest wind occurs in gusts that can be smaller than 100 yards across, or the size of a football field. We call features that cover such a small area the “turbulent scale.” Other features that are important in forecasting TCs can be as … Continue reading Paper on how getting turbulence correct in forecast models can improve intensity forecasts in sheared storms published in Monthly Weather Review
