AOML reviews science conducted during Hurricane Hunter missions into Laura

Hurricane scientists at AOML provided guidance and data support for National Hurricane Center (NHC) and Environmental Modeling Center (EMC) tasked reconnaissance into Hurricane Laura, identifying critical information about the system’s location, development, and intensification. Beginning on August 20th, 11 P-3 and 6 G-IV missions were conducted, capturing the complex lifecycle of Laura until its eventual … Continue reading AOML reviews science conducted during Hurricane Hunter missions into Laura

Lifesaving NOAA Support Following the Sinking of the Bourbon Rhode

The National Oceanic and Atmospheric Administration (NOAA) provided critical assistance during the international search and rescue (SAR) and recovery efforts that followed the sinking of the M/V Bourbon Rhode in Hurricane Lorenzo last fall.  This intra-agency NOAA effort included Hurricane Hunters from the Aircraft Operations Center (AOC), scientists from the National Environmental Satellite, Data, and … Continue reading Lifesaving NOAA Support Following the Sinking of the Bourbon Rhode

HRD Debrief for missions into EP95/Pre-Ivo in collaboration with OTREC – 3 March 2020

HRD researchers and our collaborators from the NSF-sponsored Organization of Tropical Eastern Pacific Convection (OTREC) experiment discussed the results from the 4 P-3 and 3 NCAR G-V HIAPER missions into EP95 which eventually became Hurricane Ivo in the Eastern Pacific. IFEX flew 4 P-3 missions from Liberia, Costa Rica into the disturbance that became Ivo, … Continue reading HRD Debrief for missions into EP95/Pre-Ivo in collaboration with OTREC – 3 March 2020

Paper on how tropical cyclones can intensify in high shear published in Monthly Weather Review

When the wind within about 150 miles of the center of a tropical cyclone (what we call the near environment) is very different at the bottom and the top of the storm (what we call wind shear), the storm usually weakens, especially if the storm is already weak. However, sometimes this doesn't happen, and the … Continue reading Paper on how tropical cyclones can intensify in high shear published 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
