AOML Hurricane Scientists Facilitate Leap in Hurricane Modeling and Prediction Systems

Hurricane scientists at NOAA’s Atlantic Oceanographic and Meteorological Laboratory have created a new, advanced moving nest model within the Unified Forecast System, the bedrock of NOAA’s weather prediction applications . AOML’s Hurricane Modeling and Prediction Team developed the high resolution moving nest model for the FV3 dynamical core, laying the foundation for next generation advancements in hurricane forecasting.

Drones that hunt hurricanes? NOAA puts some to the test

Originally Published January 25th, 2021 at NOAA.Gov

“We’re hopeful this new technology, once it can be successfully tested in a hurricane environment, will improve our understanding of the boundary layer and advance NOAA forecast models used in forecasts,” said Joseph Cione, lead meteorologist at NOAA’s Atlantic Oceanographic and Meteorological Laboratory Hurricane Research Division. “Ultimately, these new observations could help emergency managers make informed decisions on evacuations before tropical cyclones make landfall.”

A New Study Connects Greater Amounts of Cloud Ice in Tropical Cyclones to Intensification

A new study published in Geophysical Research Letters looks at the relationship between how fast a tropical cyclone intensifies and the amount of ice in the clouds that make up the storm. Hurricane scientists found that tropical cyclones with greater amounts of cloud ice are likely to intensify faster than those with less cloud ice.

New Study Looks at How Different Techniques to Model the Hurricane Boundary Layer Can Improve Forecasts

In a new study published in Atmosphere, hurricane scientists looked at how turbulent mixing in the boundary layer affects the intensity and structure of hurricanes in NOAA’s Hurricane Weather Research and Forecasting (HWRF) model. They found that turbulent mixing affects where thunderstorms in hurricanes occur, and how fast air flows towards the center of a storm.

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.
