Paper on how downdrafts in hurricanes affect intensity published in Monthly Weather Review

Summary: This study looks at differences between tropical cyclones that strengthen and those that do not using data collected by dropsondes, small instruments released from hurricane hunter aircraft that measure wind, temperature, and moisture as they fall to the surface. Important Conclusions: 1. The fuel that supports tropical cyclones is the heat and moisture from … Continue reading Paper on how downdrafts in hurricanes affect intensity published in Monthly Weather Review

HRD observation team monthly meeting – 15 August 2019

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 … Continue reading HRD observation team monthly meeting – 15 August 2019

HRD Seminar – George “Trey” Alvey, CIMAS/HRD – 16 July 2019

Trey presented a seminar titled “How do sheared tropical cyclones evolve towards symmetry before rapid intensification?" ABSTRACT: In seemingly similar environments, some moderately sheared tropical storms undergo rapid intensification (RI) evolving towards more symmetrical precipitation structures but others do not. What role do the vortex tilt, humidification, and precipitation symmetry play in helping distinguish those … Continue reading HRD Seminar – George “Trey” Alvey, CIMAS/HRD – 16 July 2019

2019 Hurricane Field Program Plan now available

One of the key aspects of NOAA’s Mission is, “To understand and predict changes in the climate, weather, oceans, and coasts...” with a long-term goal of achieving a, “Weather-ready Nation,” in which society is able to prepare for, and respond to, weather-related events. This objective specifies the need to improve the understanding and prediction of … Continue reading 2019 Hurricane Field Program Plan now available
