RISSecondary Eyewall Formation and Eyewall Replacement Cycles in a Simulated Hurricane: Effect of the Net Radial Force in the Hurricane Boundary Layer
Publisher: American Meteorological Society
Abstract: ultiple secondary eyewall formations (SEFs) and eyewall replacement cycles (ERCs) are simulated with the fifth-generation Pennsylvania State University (PSU)?National Center for Atmospheric Research (NCAR) Mesoscale Model ...
Verification of Mesoscale NWP Forecasts of Abrupt Cold Frontal Wind Changes
Publisher: American Meteorological Society
Abstract: During a wildfire, a sharp wind change can lead to an abrupt increase in fire activity and change the rate of spread, endangering firefighters working on what had been the flank of the fire. In southeastern Australia, ...
Revised Parameterization of Air–Sea Exchanges in High Winds for Operational Numerical Prediction: Impact on Tropical Cyclone Track, Intensity, and Rapid Intensification
Publisher: American Meteorological Society
Abstract: n high-wind conditions, sea spray, in conjunction with a generally decreasing drag coefficient for increasing winds, greatly modulates surface heat and momentum fluxes. It has been suggested that the process can be ...
Prediction and Diagnosis of the Motion and Rapid Intensification of Typhoon Sinlaku during Tropical Cyclone Structure Experiment 2008 (TCS08)
Publisher: American Meteorological Society
Abstract: he impact of initial structure on storm evolution is examined for the case of a tropical storm entering rapid intensification. At the onset of rapid intensification, satellite cloud signatures suggest that the structural ...
ACCESS-TC: Vortex Specification, 4DVAR Initialization, Verification, and Structure Diagnostics
Publisher: American Meteorological Society
Abstract: he Australian Community Climate and Earth System Simulator (ACCESS) has been adapted for operational and research applications on tropical cyclones. The base system runs at a resolution of 0.11° and 50 levels. The domain ...
