Paper on how Hurricane Michael (2018) intensified rapidly in the Gulf of Mexico released online in Monthly Weather Review

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
