Part of the difficulty of forecasting tropical cyclone (TC) track and intensity (where the TC is going and how strong it will be) stems from the lack of frequent, accurate observations over tropical oceans where TCs form and develop. While Hurricane Hunter aircraft can collect vital observations in and near TCs, those observations are limited … Continue reading Study on the impact of the new CYGNSS satellites on hurricane forecasts released online in Monthly Weather Review
NOAA has so far completed five flights into and around Hurricane Ida as it crossed over the Cayman Islands and western Cuba toward its forecast landfall along the Louisiana coast. Two synoptic surveillance missions were conducted by the NOAA G-IV high-altitude aircraft to gather dropwindsonde and Doppler radar data around the hurricane to be ingested … Continue reading Flights continue in Hurricane Ida
NOAA Hurricane Hunters completed 6 missions into Tropical Storm Fred, and 11 and 7 missions in and around Hurricanes Grace and Henri, respectively. The first mission into Fred occurred before the system had a well-defined center and was not yet named a tropical depression. Subsequent missions sampled the dry air and wind shear around Fred … Continue reading NOAA Hurricane Hunters fly into and around Fred, Grace, and Henri, and gear up for the next system

The Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS) mission is a group of satellites that will provide observations of temperature, moisture, rainfall, and water particles in the atmosphere. Planned for launch in 2022, the satellites will provide measurements that will be particularly important for studying tropical cyclones because … Continue reading Paper on the likely impact of new satellites on forecasts published in Monthly Weather Review
June's science meeting consisted of six presentations: Nick Mesa (HRD): “Investigating intensity changes related to thermodynamic processes using near-coincident aircraft and satellite observations” Sophie Grimsley (HRD): “Hurricane Intensity Change and Boundary Layer Processes” Chris Landsea (NHC): "Was 2020 a Record-Breaking Hurricane Season? Yes, but… (Why did the new average number of Named Storms go up … Continue reading HRD Monthly Science Meeting of June 2021
