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

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 – Dr. Isaac Moradi, ESSIC, University of Maryland & NASA/GSFC/GMAO – 19 April 2019

Dr. Moradi presented a seminar titled "Assimilation of Satellite Microwave Observations in the Rainband of Hurricanes Using Bayesian Monte Carlo Technique". ABSTRACT: We propose a novel Bayesian Monte Carlo Integration (BMCI) technique to retrieve the profiles of temperature, water vapor, and cloud liquid/ice water content from microwave cloudy measurements in the rainbands of tropical cyclones … Continue reading HRD Seminar – Dr. Isaac Moradi, ESSIC, University of Maryland & NASA/GSFC/GMAO – 19 April 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
