HRD observation team monthly meeting – 16 November 2017

The purpose of the observation team meetings is to bring together the people who use observations in their research on a regular basis to discuss issues they’re having, provide updates on observations they’re analyzing or collecting, and any other information that may be of interest to the broader group.  These meetings are also an excellent …

Paper on Hurricane Patricia, the most intense hurricane ever recorded in the Western Hemisphere, published in the Bulletin of the American Meteorological Society

In October 2015, off the west coast of Mexico, Hurricane Patricia became the strongest hurricane ever recorded in the western hemisphere, intensifying faster than any other storm on record. A unique set of observations were collected in Patricia. National Oceanic and Atmospheric Administration (NOAA) and National Aeronautics and Space Administration/Office of Naval Research (ONR) aircraft …

35th Anniversary of first Synoptic Flow mission

On September 14, 1982, NOAA42 flew the first Synoptic Flow Experiment around Hurricane Debby.  The idea behind the experiment was to fly a large-scale pattern around a hurricane while releasing dropwindsondes at regular intervals.  This would create a three-dimensional map of the winds steering the storm.  The data would be entered into hurricane track forecast …

25th Anniversary of Hurricane Andrew striking South Florida

In the early morning hours of August 24, 1992, Category-Five Hurricane Andrew roared across southern Florida leaving behind a trail of devastation that stunned the nation.  Andrew was the first hurricane of this ferocity to hit the continental United States since Hurricane Camille in 1969, and repercussions of its landfall were felt in the world …

Review of extratropical transition published in Monthly Weather Review

Summary: When tropical cyclones move out of the tropics toward the poles, they reach areas where fronts exist and where the ocean, whose warm water fuels tropical storms, is relatively cool. When this happens, the storms go through extratropical transition (ET) and become like other storms in the mid latitudes. The storms can cause catastrophic …
