September's science meeting consisted of three presentations: Andy Hazelton - "HAFSV0.1B (HAFS-globalnest) performance for Hurricane Laura: Verification and Evaluation of TC structure"Evan Forde - “Identification of Atlantic Basin Tropical Cyclones in Proximity to Significant Dry Air Events in Total Precipitable Water Imagery (1987-2015)”Sim Aberson - "In Search of the Elusive Eyewall Me/iso-scale ?" The three presentations are … Continue reading HRD Monthly Science Meeting of September 2020
Our very own Jason Dunion was recently featured on the Netflix show Connected: The Hidden Science of Everything. He took journalist Latif Nasser aboard a NOAA Hurricane Hunter aircraft to look at how the Saharan Air Layer influences hurricane development.The Saharan Air Layer is a mass of very dry, dusty air that forms over the Sahara … Continue reading Jason Dunion on Connected: The Hidden Science of Everything
After a busy start to the 2020 Atlantic hurricane season, AOML scientists prepare for upcoming tropical cyclone activity that may pose a threat to the U.S. and its territories. Close collaboration among AOML hurricane scientists, the National Hurricane Center (NHC), and the Environmental Modeling Center (EMC) allows for a comprehensive consideration of potential tropical cyclone targets for NOAA aircraft … Continue reading AOML monitors tropics for potential hurricane development
NOAA’s P-3 aircraft named “Miss Piggy” will continue Environmental Modeling Center (EMC) tasked reconnaissance into Hurricane Isaias by penetrating the core of its circulation multiple times in order to obtain the most reliable measurements of its environmental conditions. The aircraft took off from Lakeland, FL today at 4:00 PM. AOML scientists acquire and process data … Continue reading Hurricane scientists at AOML provide support for missions into Hurricane Isaias
As we move through the 2020 Atlantic Hurricane Season, you will no doubt hear a lot about the Saharan Air Layer—a mass of very dry, dusty air that forms over the Sahara Desert during the late spring, summer and early fall. This layer can travel and impact locations thousands of miles away from its African … Continue reading The Saharan Air Layer: What is it? Why does NOAA track it?
Both NOAA43 and NOAA49 are now in Barbados prepared for missions into Hurricane Lorenzo. NOAA49 will conduct a NESDIS Satellite Validation and Diurnal Cycle Experiment, takeoff from Barbados 0800 AST/EDT (1200 UTC). The goal is to sample the region around Lorenzo, including the Saharan Air Layer, and regions deemed sensitive to future forecasts. There will … Continue reading Hurricane Field Program Update — Thursday, September 26, 2019, 5pm EDT
NOAA49 will conduct a mission in and around Tropical Depression 10, departing Barbados at 0900 local time (1300 UTC), and returning there about 8 hours later. The aircraft will perform a lawnmower pattern to sample the environment and a circumnavigation of the system about 120 n mi from the center. The goal is to sample … Continue reading Hurricane Field Program Update — Tuesday, September 17, 2019, 10pm EDT
