Hurricane Field Program Update — Tuesday, August 20, 2019

HRD successfully completed their last research NOAA P-3 mission into Invest 95E, located in the East Pacific, today collecting valuable data that will help towards better understanding how tropical storms develop. The data from the flight reveals the complicated circulation structure in developing storms and their link to precipitation (rainfall) processes, which are critical to … Continue reading Hurricane Field Program Update — Tuesday, August 20, 2019

HRD Seminar – Jonathan Martinez, Colorado State University – 20 August 2019

Jonathan presented a two-part seminar with titles; Part I: "Axisymmetric Potential Vorticity Evolution of Hurricane Patricia (2015)" and Part II: "On the Contributions of Incipient Vortex Circulation and Environmental Moisture to Tropical Cyclone Expansion”. Part I: Axisymmetric Potential Vorticity Evolution of Hurricane Patricia (2015) Abstract Operational numerical models failed to predict the record-setting rapid intensification and … Continue reading HRD Seminar – Jonathan Martinez, Colorado State University – 20 August 2019

Hurricane Field Program Update — Monday, August 19, 2019

HRD and the National Center for Atmospheric Research (NCAR) / National Science Foundation (NSF) Organization of Organization of Tropical East Pacific Convection (OTREC) East Pacific Convection (OTREC) Experiment team (see for details: https://www.eol.ucar.edu/field_projects/otrec) flew a joint research mission yesterday (Sunday) with the NCAR/NSF G-V high-altitude airplane flying a lawnmower pattern around the disturbance environment associated … Continue reading Hurricane Field Program Update — Monday, August 19, 2019

Hurricane Field Program Update — Monday, August 19, 2019

HRD and the NOAA Hurricane Hunters successfully flew the first hurricane formation (aka, genesis) research mission out of Costa Rica yesterday into the disturbance identified as Invest 95E by the National Hurricane Center (NHC). The NOAA P-3 (NOAA42, “Kermit”) flew a complete “lawnmower” pattern encompassing the broad circulation observed in the Invest. HRD has tasked […]

Hurricane Field Program Update — Saturday, August 17, 2019

HRD has tasked the NOAA P-3 (NOAA42, aka "Kermit") to fly research missions into a potentially developing storm in the East Pacific, currently identified as Invest 95E by the National Hurricane Center. The P-3 ferried down to Costa Rica yesterday. Operating missions out of Liberia, Costa Rica, the goal of our research missions will be … Continue reading Hurricane Field Program Update — Saturday, August 17, 2019

Hurricane Field Program Update — Friday, July 12, 2019

A NOAA P-3 ("Kermit") mission into Tropical Storm Barry this morning successfully sampled the structure of the storm and completed data collection objectives for NOAA/NCEP Environmental Modeling Center (EMC). Shown below, they completed a rotated Figure 4 pattern, four passes through the center, dropping dropsondes throughout the pattern and collecting valuable Doppler radar data. The … Continue reading Hurricane Field Program Update — Friday, July 12, 2019

Hurricane Field Program Update — Thursday, July 11, 2019

The second EMC-tasked NOAA P-3 (NOAA 42, aka "Kermit") mission into Tropical Storm Barry successfully completed their flight objectives this morning, landing back in Lakeland, FL around 11 am EDT. Below shows the completed flight pattern, in which the crew flew a "butterfly" pattern sampling multiple legs through the developing center of the storm. After the … Continue reading Hurricane Field Program Update — Thursday, July 11, 2019

Hurricane Field Program Update — Wednesday, July 10, 2019

The first NOAA P-3 mission of the 2019 hurricane season is scheduled to take off from Lakeland, FL at 4 pm EDT (2000 UTC) this afternoon to sample Potential Tropical Cyclone Two in the northeastern Gulf of Mexico. The P-3 "Kermit" (NOAA42) will fly a lawnmower pattern (shown below) to collect data for NOAA's National … Continue reading Hurricane Field Program Update — Wednesday, July 10, 2019
