Wind structure in the hurricane boundary layer shows pronounced asymmetries over water and at landfall. Aircraft observations have noted significant changes in the nature of these asymmetries prior to and during Hurricane Ida’s landfall. Such changes can have important implications for damage patterns during TC landfall, and understanding the physical processes underlying these changes can […]

This research investigates how the distribution of different types of precipitation are related to tropical cyclone (TC) intensity change. Even though deep convection – the tallest clouds – is the least frequent type of precipitation in TCs, the amount of deep convection, especially when it is evenly distributed around the TC center, has the strongestrelationship […]

The Global Positioning System dropwindsonde has provided thousands of high-resolution soundings of wind velocity, temperature, moisture, and humidity in and around tropical cyclones (TCs) since 1997. These data have revolutionized the understanding of TC structure, improved forecasts, and validated observations from remote-sensing platforms like satellites. About 400 peer-reviewed studies on TCs using these data have […]

The new Hurricane Analysis and Forecast System (HAFS) became operational (i.e., used by the National Hurricane Center in their official forecasts) for the 2023 hurricane season. HAFS was run during the 2022 hurricane season in the Atlantic and East Pacific to test it before designing the final version. We found encouraging track forecasts results, including […]

AOML/HRD supported 19 operationally tasked NOAA NHC/EMC P-3 Tail Doppler Radar and G-IV Synoptic Surveillance missions into Hurricane Lee from the time it became a category-5 hurricane to its extratropical transition and landfall in Nova Scotia. HRD collaborated with partners in AOML/Physical Oceanography Division, the Office of Naval Research, NOAA’s National Environmental Satellite, Data, and […]
