Paper on the likely impact of new satellites on forecasts published in Monthly Weather Review

The Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS) mission is a group of satellites that will provide observations of temperature, moisture, rainfall, and water particles in the atmosphere.  Planned for launch in 2022, the satellites will provide measurements that will be particularly important for studying tropical cyclones because …

Jason Dunion, Frank Marks, and Rob Rogers participate in the WMO-sponsored Tropical Cyclone-Probabilistic Forecast Products Workshop

The World Meteorological Organization (WMO) hosted a three-day virtual workshop on June 15, 17, and 18 to chart a path forward for evaluating, developing, and improving tropical cyclone probabilistic forecast products (TC-PFP). Co-led by Jason Dunion (NOAA/AOML/HRD and UM/CIMAS), Munehiko Yamaguchi (Japanese Meteorological Agency), and Hui Yu (Shanghai Typhoon Institute) as part of the WMO Working …

HRD scientists participate in the 34th American Meteorological Society Conference on Hurricanes and Tropical Meteorology

34th Conference on Hurricanes and Tropical Meteorology Virtual Meeting The 34th AMS Conference on Hurricanes and Tropical Meteorology was held virtually 10-14 May after being postponed from 2020. This is the premiere meeting for operational and research scientists who work on understanding and forecasting tropical cyclones and other tropical weather around the world. HRD scientist …

Paper that reviews what we know about intensity change published in Atmosphere

This paper is an overview of what we currently know about processes important in tropical cyclone intensity change and the research that has been done during the past 15 years using aircraft data. The paper describes the eye and eyewall and how they change in time, the region close to the ocean surface where the …

You can catch Jon Zawislak, Rob Rogers, Joe Cione, and Shirley Murillo talking about hurricanes, or listen in on recordings of panels on coasts and coral reefs, and ocean research, and even a panel …

Paper describing how tropical cyclones in shear rapidly develop published in the Journal of the Atmospheric Sciences

Tropical Cyclones (TCs) occur over warm water in the ocean, and this warmth and moisture is what feeds the engine that keeps the TC going.  They are made up of thunderstorms, what we call deep convection, and within the convection, there are both convective updrafts and convective downdrafts.  The temperature in the atmosphere goes down …
