Hurricane Field Program Update — Sunday, September 29, 2019, 10pm EDT

All three NOAA aircraft flew in and around Hurricane Lorenzo today, with both P3s flying the same tracks (at 8 and 10 kft) through the storm within 15 minutes of each other. The G-IV departed the storm just as the P3s were entering. The G-IV flew an HRD research mission in support of the NESDIS … Continue reading Hurricane Field Program Update — Sunday, September 29, 2019, 10pm EDT

Hurricane Field Program Update — Saturday, September 28, 2019, 11pm EDT

All three NOAA hurricane hunter aircraft were airborne at the same time today, in and around Hurricane Lorenzo. The G-IV flew a successful HRD research mission in support of the NESDIS Satellite Validation experiment, flying around Lorenzo in a star pattern that sampled the environmental interaction and aligning the pattern with an NOAA-20 overpass to … Continue reading Hurricane Field Program Update — Saturday, September 28, 2019, 11pm EDT

Hurricane Field Program Update — Friday, September 27, 2019, 5pm EDT

All three aircraft, NOAA42, NOAA43, and NOAA49, are now in Barbados due to Hurricane Lorenzo.  NOAA43 spent today conducting a search-and-rescue mission for the tug supply vessel Bourbon Rhode, while NOAA49 conducted its mission as scheduled.  For tomorrow, NOAA42 will conduct another search-and-rescue mission for the tug, while NOAA43 and NOAA49 conduct research missions. NOAA49 will … Continue reading Hurricane Field Program Update — Friday, September 27, 2019, 5pm EDT

Hurricane Field Program Update — Thursday, September 26, 2019, 5pm EDT

Both NOAA43 and NOAA49 are now in Barbados prepared for missions into Hurricane Lorenzo.  NOAA49 will conduct a NESDIS Satellite Validation and Diurnal Cycle Experiment, takeoff from Barbados 0800 AST/EDT (1200 UTC).  The goal is to sample the region around Lorenzo, including the Saharan Air Layer, and regions deemed sensitive to future forecasts.  There will … Continue reading Hurricane Field Program Update — Thursday, September 26, 2019, 5pm EDT

Hurricane Field Program Update — Friday, August 29, 2019, 7pm EDT

We remain very busy with Hurricane Dorian.   NOAA42 is currently conducting a NHC- and EMC-tasked reconnaissance flight into Dorian.  On their first pass, they found that Dorian was rapidly intensifying and now had a minimum central pressure of 951 mb from dropsonde, and the stepped-frequency microwave radiometer reported surface wind speed of 112 kt … Continue reading Hurricane Field Program Update — Friday, August 29, 2019, 7pm EDT

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

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
