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 Centers for Environmental Prediction (NCEP) Environmental Modeling Center (EMC). The data collected on the mission — which includes dropsondes (measuring the humidity and wind in the atmosphere) and a Doppler radar (measuring the 3D rainfall and wind structure) — will be assimilated into the Hurricane Weather Research and Forecasting (HWRF) model to help produce a better representation of the atmosphere in the northern Gulf of Mexico at the start of its forecast run.

Subsequent missions, tasked by EMC, will be flown at 4 am EDT (0800 UTC) Thursday morning, 4 pm EDT (2000 UTC) Thursday afternoon and 4am EDT Friday morning. HRD will have 3 to 4 scientists on each mission supporting data collection.
