In a recent study published in AGU’s Journal of Geophysical Research – Oceans, scientists at AOML identified key ocean features that supported the rapid intensification of Hurricane Michael (2018), despite unfavorable atmospheric conditions for development. The study demonstrates the importance of using realistic ocean conditions for coupled (ocean-atmosphere) hurricane models in order to achieve the most accurate hurricane intensity forecasts.
In a recent study published in Weather and Forecasting,* AOML researchers and their colleagues used NOAA’s HWRFHYCOM operational hurricane forecast model to quantify the impact of assimilating underwater glider data and other ocean observations into the intensity forecasts of Hurricane Gonzalo (2014). Gonzalo formed in the tropical North Atlantic east of the Lesser Antilles on October […]
Underwater gliders observations reveal the importance of salinity effects during passage of Hurricane Gonzalo (2014)
Hurricanes are known to drive the cooling of surface waters as they travel over the ocean, leaving a cooling swath where they pass. The sea surface cooling is mostly caused by mixing forced by the strong winds of the hurricane, which occurs as the mixture of warm surface waters with colder waters that can be as deep as 100 m below the surface.
