Paper on the direct measurement of important air-sea interaction parameters in tropical cyclones published in the Journal of Geophysical Research

Summary:Friction is what happens when two things rub up against each other; when this happens, they release heat. When this happens in the atmosphere, we call it “dissipative heating.” Tropical cyclones (TCs) mainly gather energy from the warm ocean at the boundary layer, the region from the surface of the ocean to an altitude of …

HRD Seminar – Bill Ramstrom, Verisk Weather Solutions – 6 August 2018

Mr. Ramstrom presented a seminar titled "Damage Rates from Insurance Claims for Coastal and Inland Areas in Hurricanes Harvey and Irma". ABSTRACT: Insurance claims data provides a highly detailed view of the geographic patterns of damage in hurricanes. This talk will cover analytics that correlate claims percentages with maximum winds and rainfall during the landfalls …

2018 Hurricane Field Program now available

Since 1956, the Hurricane Research Division has carried out an annual field program in which data on Atlantic hurricanes is collected from a variety of platforms, primarily NOAA aircraft.  Since the early 1970s plans for particular experiments were documented prior to the start of the season, to better allocate resources and personnel. This year's plan …

Paper on Hurricane Patricia, the most intense hurricane ever recorded in the Western Hemisphere, published in the Bulletin of the American Meteorological Society

In October 2015, off the west coast of Mexico, Hurricane Patricia became the strongest hurricane ever recorded in the western hemisphere, intensifying faster than any other storm on record. A unique set of observations were collected in Patricia. National Oceanic and Atmospheric Administration (NOAA) and National Aeronautics and Space Administration/Office of Naval Research (ONR) aircraft …
