New study on how changes in ocean temperature near the coast during landfall can intensify hurricanes released online in Geophysical Research Letters
This study uses a state-of-the-art hurricane modeling system developed at the NOAA/Atlantic Oceanographic and Meteorological Laboratory’s Hurricane Research Division, the Basin-Scale Hurricane Weather Research and Forecast (HWRF-B) model, to demonstrate a link between an oceanographic process called coastal downwelling and the intensification of tropical cyclones (TCs or hurricanes) near landfall. We show that coastal downwelling … Continue reading New study on how changes in ocean temperature near the coast during landfall can intensify hurricanes released online in Geophysical Research Letters

Paper describing ocean gliders and saildrones for hurricane observations published in Oceanography
Autonomous underwater gliders and uncrewed surface vehicles such as saildrones are revolutionizing both our understanding of and ability to forecast hurricane track and intensity. These observing systems are becoming critical components of operational forecasting systems in the United States. Extreme weather (short-wing) Saildrone and its measurement capabilities (https://www.saildrone.com/news/what-is-saildrone-how-work).

Study on using neural networks to estimate tropical cyclone intensity using satellite imagery published in IEEE Transactions on Geoscience and Remote Sensing
The intensity of most tropical cyclones around the world are estimated by using satellite images. This study designed and evaluated convolutional neural network (CNN) models for estimating tropical cyclone intensity using geostationary satellite images. The selection of infrared channels was found to significantly affect the performance of these models. This work pointed out the best … Continue reading Study on using neural networks to estimate tropical cyclone intensity using satellite imagery published in IEEE Transactions on Geoscience and Remote Sensing

Study on improvements to NOAA’s hurricane forecast model and the way it predicts the region closest to the surface published in Weather and Forecasting
We modified the way NOAA’s new hurricane model forecasts what happens in the lowest part of the atmosphere based on observations from Hurricane Hunter research flights. The new scheme produced track forecasts that were up to 20% better than from the older scheme, a 15% improvement in detection of rapid intensification events, and smaller tropical … Continue reading Study on improvements to NOAA’s hurricane forecast model and the way it predicts the region closest to the surface published in Weather and Forecasting
