Dr. Poterjoy presented a seminar titled “Regional Weather Prediction Using an ‘Iterative’ Local Particle Filter”. ABSTRACT: Particle filters (PFs) are sequential Monte Carlo methods that can solve data assimilation problems characterized by non-Gaussian error distributions for prior model variables or measurements. From the perspective of a geoscientist, PFs contain several theoretical properties that make them […]
NOAA scientists flew multiple missions into Hurricane Michael in the days before landfall, closely observing the rapid intensification of the storm. Their tools included a small uncrewed aircraft, called the Coyote, which flew into the strongest winds of the eyewall as the storm intensified to a category 4 on the Saffir-Simpson scale. NOAA has […]

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 […]
Tuesday, October 9, 2018: NOAA42: The NOAA/NCEP/Environmental Modeling Center (EMC) has tasked the P-3 for an operational mission into Hurricane Michael. Take off from Lakeland, FL will be at 4:00 PM EDT. Four HRD scientists will be on this mission. The flight track of the mission is shown below. The goal is to collect Doppler […]
Monday, October 8, 2018: NOAA42: The NOAA/NCEP/Environmental Modeling Center (EMC) has tasked the P-3 for operational missions into Hurricane Michael, currently located east of the Yucatan Peninsula. Take off from Lakeland, FL, will be at 4:00 PM EDT. Three HRD scientists will be on this mission. The flight track of the mission is shown below. […]
Sonia was named Team Member of the Month for her work providing part-time support to NOAA’s Aircraft Operations Center (AOC) as a software engineer and troubleshooter. Sonia programs complex code that is executed aboard NOAA aircraft and spent the past year working to ensure that AOC’s aircraft weather messages were properly assimilated into the weather […]

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 […]
