HRD Seminar – Dr. David Ryglicki, Naval Research Laboratory – 17 August 2017

Dr. Ryglicki presented a seminar titled  “The Kinematics of Rapidly Intensifying Hurricanes in Moderate Vertical Wind Shear”. Abstract: A select group of tropical cyclones (TCs) which unexpectedly undergo rapid intensification in moderate vertical wind shear are identified, analyzed, and modeled. Geostationary satellite and reanalysis data are used to identify features and environmental parameters of these TCs. […]

25th anniversary of first tropical cyclone track forecast from NOAA’s Global Model

At 00 UTC, a new implementation of NOAA’s global spectral model, then called the Aviation Model, produced a track forecast for Tropical Storm Andrew in the Atlantic.  Earlier in the year, the model was upgraded so that it now had a resolution of about 210 km, and it had 18 levels in the vertical.  Compare […]

Review of extratropical transition released online in Monthly Weather Review

Summary: When tropical cyclones move out of the tropics toward the poles, they reach areas where fronts exist and where the ocean, whose warm water fuels tropical storms, is relatively cool. When this happens, the storms go through extratropical transition (ET) and become like other storms in the mid latitudes. The storms can cause catastrophic […]
