Paper on the impact of using Hurricane Hunter data in the HWRF model published in Monthly Weather Review

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

Paper on how getting turbulence correct in forecast models can improve intensity forecasts in sheared storms 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
