Hurricane Field Program Update – Wednesday, October 10, 2018

The NOAA P-3 completed its last mission into Hurricane Michael this morning, passing through the storm four times. As in the previous three missions, we provided critical measurements of the 3-D wind, precipitation, and thermodynamic (temperature and humidity) structure of the storm from our Doppler radar, dropsondes, and flight level measurements. The data was not … Continue reading Hurricane Field Program Update – Wednesday, October 10, 2018

55th Anniversary of Hurricane Flora

On the night of October 3, 1963, Hurricane Flora smashed into the southern coast of Haiti.  It raked the country with 145 mph (230 km/hr) winds and dumped tremendous downpours on its mountains.  It would become one of the deadliest and wettest Atlantic hurricanes on record. Flora began as an African easterly wave, moving over … Continue reading 55th Anniversary of Hurricane Flora

HRD Seminar – Saiprasanth Balachandran, Purdue University – 5 September 2018

Mr. Balachandran presented a seminar titled “Spatial, temporal, and spectral characteristics of convective asymmetries driving rapid intensity changes in tropical cyclones”. ABSTRACT: Understanding the role of convective asymmetries in influencing a change in tropical cyclone (TC) intensity is a challenging task. The inherent difficulty is because asymmetries can arise from different sources, occur at different … Continue reading HRD Seminar – Saiprasanth Balachandran, Purdue University – 5 September 2018

HRD researchers discussed the results from the 4 G-IV and 4 P-3 missions into Central Pacific Hurricane Lane (19-23 August 2018) representing the first NOAA P-3 mission to fly a Central Pacific storm. The agenda for the discussion was: Agenda: Storm Overview (Jon Zawislak) Missions Overview (Jon Zawislak) Deployment Overview (Jon Zawislak) CPHC Feedback (Tom Birchard, … Continue reading HRD Debrief for missions into Hurricane Lane – 30 August 2018

Paper on low-level downdrafts and their impact on intensity released online in Monthly Weather Review

Summary: In this study, we looked at radar, thermodynamic (temperature and humidity), and sea surface temperature data from the National Oceanic and Atmospheric Administration Hurricane Hunter and National Aeronautics and Space Administration aircraft in Hurricane Earl (2010). We found that there are different types of downdrafts (air moving downward) near the strongest part of the … Continue reading Paper on low-level downdrafts and their impact on intensity released online in Monthly Weather Review

35th Anniversary of Hurricane Alicia

In the early morning hours of August 18, 1983, Hurricane Alicia made landfall at San Luis Pass, Texas, just southwest of the Galveston area.  Its 115 mph (185 km/hr) winds slammed the high rises of Houston leaving billions of dollars in damage in its wake. Like many tropical storms that form during low-activity years, Alicia … Continue reading 35th Anniversary of Hurricane Alicia
