In late August 2022, both NOAA P-3s and its G-IV jet are engaging in a series of missions to examine an area of disturbed weather over the tropical Atlantic. As part of the Impact of Targeted Observations on Forecasts (ITOFs) project scientists are examining such tropical waves to learn why some of them form into […]
On August 27, 2022, the City of Homestead in conjunction with the Cybrarium and Town Hall Museum will host a commemoration of the 30th Anniversary of Hurricane Andrew. The Category 5 hurricane had profound effects on Homestead, the Air Force Base, and the people of southern Miami-Dade County. AOML’s Hurricane Research Division will participate in […]
Hurricane Andrew made landfall on August 24, 1992, near Homestead, Florida, becoming one of the most catastrophic hurricanes in U.S. history. It had an extremely low central pressure of 922 millibars and maximum sustained wind speeds estimated at 165 miles per hour. The storm rapidly intensified less than 36 hours before landfall, leaving most residents less […]
Physical parameterizations in computer models need to consider the unique structures of tropical cyclones. The study helps us understand turbulent mixing to advance how we account for it in our forecast model parameterizations to improve forecasts. Summary: Tropical cyclones are fueled by the heat from the warm ocean below. This heat energy moves upward into […]
This study uses the observations from Hurricane Hunter aircraft to investigate the inflow of warm, moist air into the tropical cyclone (TC) center that fuels the circulation. Specifically, the inflow angle is the difference between the wind direction and the direction of a circular wind that does not flow into the center. The study found […]
HRD director Frank Marks participated in WeatherBrains podcast 864 to discuss the Lakeland High School Weather Club’s impact on the field of meteorology in the U.S.. In October 1967, Weatherwise magazine ran an article entitled, “Meteorology at Lakeland High School,” about an advanced high school Weather Club, and in January 2022 Weatherwise provided a 55 year […]
August’s science meeting consisted of two presentations: Henry Winterbottom (ESRL/PSL): “Simulating Tropical Cyclones Within the Unified Forecast System (UFS): The Impacts of Nesting and TC Relocation” Stanley Goldenberg: “August Update for NOAA’s Outlook for the 2022 Atlantic Hurricane Season: Methodology and Forecast” Copies of the two presentations are available here.
As part of the Impact of Targeted Observations on Forecasts-East (ITOFs-East) project project, NOAA’s G-IV jet “Gonzo” has conducted three missions on subsequent days sampling the area of disturbed weather (AL97) and the Saharan Air Layer (SAL) to its north. With AL97 decaying, the August 11th mission is simply to release 8 dropsondes in the […]
On August 9, 2022, NOAA’s G-IV jet “Gonzo” completed its first ever mission from the Cabo Verde Islands in the eastern Atlantic. The mission was part of the Impact of Targeted Observations on Forecasts-East (ITOFs-East) project, which seeks to examine African Easterly Waves as they move off the western African coast over the tropical Atlantic […]
