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 takeoff 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 Centers … Continue reading Hurricane Field Program Update — Wednesday, July 10, 2019

HRD Seminar – Jeff Steward, UCLA / National Central University in Taiwan – 25 June 2019

Jeff presented a seminar titled “Solving the Ensemble Square-Root Kalman Filter equations using matrix functions without an actual matrix - the "perfect" large-scale, scalable parallel method to assimilate all-sky satellite radiances in an ensemble” ABSTRACT: All-sky (clear or cloudy) satellite radiances are difficult to assimilate, but have a huge potential to improve NWP forecasts such … Continue reading HRD Seminar – Jeff Steward, UCLA / National Central University in Taiwan – 25 June 2019

HRD Seminar – Addison Alford, University of Oklahoma – 17 June 2019

Addison presented a seminar titled "Radar Observations of Landfalling Hurricanes: Synthesizing Three Years of SMART Radar Missions" ABSTRACT: The Shared Mobile Atmospheric Research and Teaching radars observed five landfalling tropical cyclones (TCs) from 2016-2018. The observations were largely targeted toward understanding asymmetric convective and dynamic processes. Such processes are thought to lead to the intensification … Continue reading HRD Seminar – Addison Alford, University of Oklahoma – 17 June 2019
