Paper on differences in rainfall between tropical disturbances that form into tropical cyclones and those that don't released online 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 released online in Monthly Weather Review

AOML Flies Science Missions into Succession of Atlantic Storms

“Many of the storms we flew in 2019 were ‘living on the edge,’ in that they were weak, vertically sheared, but also unpredictable. In previous years, we saw these storms intensify, such as Hurricane Michael in 2018. This season, many struggled to intensify. As we continue to build a dataset of these sheared storms, we … Continue reading AOML Flies Science Missions into Succession of Atlantic Storms

2019 Hurricane Field Program Season in Review and Hotwash, 13 November 2019

The purpose of the season review and "hotwash" is to review the highlights from the season and discuss what went right / what went wrong / and what could be done better in the future with respect to Hurricane Field Program operations/plans/logistics, as well as provide feedback to AOC about the aircraft and their operations. … Continue reading 2019 Hurricane Field Program Season in Review and Hotwash, 13 November 2019

Scientists show how Hurricane Edouard in 2014 rapidly intensified despite wind shear and dry air in paper released online in The Journal of the Atmospheric Sciences

Summary:  Tropical cyclones (TCs) usually weaken when there is a large change in the wind speed or direction with height (wind shear) or when there is dry air in the core.  Some TCs, like Hurricane Edouard (2014) can intensify, even rapidly, under these conditions. We use a series of model runs to understand how a … Continue reading Scientists show how Hurricane Edouard in 2014 rapidly intensified despite wind shear and dry air in paper released online in The Journal of the Atmospheric Sciences

Paper on how downdrafts in hurricanes affect intensity published in Monthly Weather Review

Summary: This study looks at differences between tropical cyclones that strengthen and those that do not using data collected by dropsondes, small instruments released from hurricane hunter aircraft that measure wind, temperature, and moisture as they fall to the surface. Important Conclusions: 1. The fuel that supports tropical cyclones is the heat and moisture from … Continue reading Paper on how downdrafts in hurricanes affect intensity published in Monthly Weather Review
