AOML Scientists Assess Hurricane Delta’s Rapid Intensification

NOAA aircraft reconnaissance continued for Major Hurricane Delta on October 6, capturing the system’s quick maturation overnight. P-3 and G-IV missions are scheduled every 12 and 24 hours from Lakeland, FL. The National Hurricane Center (NHC) tasked NOAA’s Hurricane Hunters to identify the location and strength of the circulation center, and to survey the atmospheric conditions nearby and ahead of Delta. Instrumentation onboard the aircraft have sampled the system’s development, revealing a 55 knot rapid intensification in just 24 hours.

Sally Intensifies Near the Gulf Coast as Observed by NOAA Reconnaissance

NOAA’s G-IV and two P-3 Hurricane Hunter aircraft took off from Lakeland, FL at 10:30 AM, 1:30 PM and 4:30 PM EDT on September 14th to investigate Hurricane Sally’s circulation. AOML scientists providing onboard and remote support for these missions ensure that Tail Doppler Radar, dropsonde, and Stepped Frequency Microwave Radiometer (SFMR) measurements allow for adequate coverage of the storm environment.

NOAA’s Multi-Storm HWRF-B Model Uses Atmosphere/Ocean Interactions to Improve Tropical Cyclone Forecasts

A recent paper published in Atmosphere introduces a new update to the Basin-Scale Hurricane Weather Research and Forecasting (HWRF-B) model, which pairs an atmospheric model with an ocean model via new coupling technology to forecast several tropical cyclones simultaneously. This model, shown to improve forecast skill, was developed at AOML in collaboration with NOAA’s Environmental Modeling Center and the Developmental Testbed Center.
