Scientists Sample Multiple Storms as Tropics Enter Peak for Hurricane Formation

Hurricane scientists at AOML sampled multiple storms this summer as the ­Atlantic entered its peak period for hurricane ­formation. From Elsa to Sam, the observations they gathered supported NOAA’s mission of preparing the public for severe weather by providing critical data for ­accurate, up-to-date forecasts.

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.

Modeling Michael: Using NOAA’s HFV3 to predict rapid intensification in Hurricane Michael

In a recently published study, AOML hurricane researchers used multiple computer model forecasts to gain a better understanding of how Hurricane Michael, which made landfall in the panhandle of Florida with winds up to 162 mph, rapidly intensified despite strong upper-level wind shear which usually weakens hurricanes. By contrasting two sets of forecasts, the study found that Michael only rapidly intensified when rainfall completely surrounded Michael’s center, and when the eye of the storm itself was located in nearly the same place at different heights.
