Weather forecasters use computer models to make predictions. These forecasts of the future depend on knowing what is happening now, what we call initial conditions. However, we can't measure the weather at every location on earth all the time, so we don't know exactly what these initial conditions are. Therefore, we run forecast models many … Continue reading Paper on how Hurricane Michael (2018) intensified rapidly in the Gulf of Mexico released online in Monthly Weather Review

Paper on differences in rainfall between tropical disturbances that form into tropical cyclones and those that don’t published in Monthly Weather Review
Summary: Many weather satellites are outfitted with instruments that can see through clouds to sense where and how hard it is raining (the rain rate), and how much of the rain is occurring in deep convective clouds (cumulus and cumulonimbus clouds that form when warm air rises). They can also see tropical disturbances, which are usually … Continue reading Paper on differences in rainfall between tropical disturbances that form into tropical cyclones and those that don’t published in Monthly Weather Review

Hurricane Field Program Update — Friday, July 12, 2019
A NOAA P-3 ("Kermit") mission into Tropical Storm Barry this morning successfully sampled the structure of the storm and completed data collection objectives for NOAA/NCEP Environmental Modeling Center (EMC). Shown below, they completed a rotated Figure 4 pattern, four passes through the center, dropping dropsondes throughout the pattern and collecting valuable Doppler radar data. The … Continue reading Hurricane Field Program Update — Friday, July 12, 2019
55th Anniversary of Hurricane Flora
On the night of October 3, 1963, Hurricane Flora smashed into the southern coast of Haiti. It raked the country with 145 mph (230 km/hr) winds and dumped tremendous downpours on its mountains. It would become one of the deadliest and wettest Atlantic hurricanes on record. Flora began as an African easterly wave, moving over … Continue reading 55th Anniversary of Hurricane Flora

35th Anniversary of Hurricane Alicia
In the early morning hours of August 18, 1983, Hurricane Alicia made landfall at San Luis Pass, Texas, just southwest of the Galveston area. Its 115 mph (185 km/hr) winds slammed the high rises of Houston leaving billions of dollars in damage in its wake. Like many tropical storms that form during low-activity years, Alicia … Continue reading 35th Anniversary of Hurricane Alicia
