Summary: The energy that fuels tropical cyclones comes from the heat and moisture in the warm ocean water below. In a classical theory for tropical cyclone intensification, called Wind Induced Surface Heat Exchange or WISHE, an increase in surface wind speed allows for greater energy transfer from the ocean to the atmosphere (Fig. 1a). This […]
March’s science meeting consisted of three presentations. Michael Fischer: “How are TC convective and vortex characteristics related to TC intensity?” Josh Wadler: “The Effects of Environmental Wind Shear Direction on Tropical Cyclone Boundary Layer Thermodynamics and Intensity Change from Multiple Observational Datasets” Lew Gramer: “Coastal downwelling and landfalling hurricane intensification” Copies of the three presentations are available […]
Dr. Masters presented a seminar titled “Collecting surface wind and water data in extreme hydrodynamic conditions during tropical cyclone landfall: The Sentinel Project”. ABSTRACT: The presentation will describe a new effort to measure surface wind, hydrodynamic, erosion, and water quality conditions in the hurricane core at the coastal transition. In this region, storm surge and […]
February’s science meeting was hosted by NHC and consisted of nine presentations. The first two presented an overview of the proposed Tropical Marine Testbed (TMT) from a NWS and OAR perspective, and the remaining seven presentations were from NHC and HRD researchers describing potential projects that the TMT might tackle: Overview of Tropical Marine Testbed […]
Numerical weather forecast models run on a grid, or regularly spaced group of points that cover the particular area of interest. These models combine weather observations with equations that explain the motions in the atmosphere and ocean. Two types of models are used to make the most accurate forecasts possible. Global models analyze and forecast […]

An important tool that forecasters use to predict the weather is a set of computer models that forecast things such as the wind, temperature, moisture, and pressure on a set of places called grid points. In NOAA’s models to predict hurricanes, the distance between these points is about 1-3 km. Although hurricanes are hundreds of […]
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 […]
