Study on the impact of the new CYGNSS satellites on hurricane forecasts released online in Monthly Weather Review

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

Flights continue in Hurricane Ida

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

HRD Monthly Science Meeting of July 2021

July's science meeting consisted of five presentations: Sophie Grimsley (Lapenta Intern): "Project Check-in: Hurricane Intensity Change and Boundary Layer Processes" Nick Mesa (Lapenta Intern): "Investigating Intensity Changes Related to Thermodynamic Processes Using Near-coincident Aircraft and Satellite Observations" Laura Ko: "A Consensus Machine Learning Model for Hurricane RI Probabilistic Predictions" Sim Aberson: "Including High-Resolution AMVs in … Continue reading HRD Monthly Science Meeting of July 2021

Paper on the likely impact of new satellites on forecasts published in Monthly Weather Review

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

HRD Monthly Science Meeting of June 2021

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

HRD scientists participate in the 34th American Meteorological Society Conference on Hurricanes and Tropical Meteorology

34th Conference on Hurricanes and Tropical Meteorology Virtual Meeting The 34th AMS Conference on Hurricanes and Tropical Meteorology was held virtually 10-14 May after being postponed from 2020. This is the premiere meeting for operational and research scientists who work on understanding and forecasting tropical cyclones and other tropical weather around the world. HRD scientist … Continue reading HRD scientists participate in the 34th American Meteorological Society Conference on Hurricanes and Tropical Meteorology

Paper on how the ocean allowed for the intensification of Hurricane Michael to category-5 status before landfall published in the Journal of Geophysical Research – Oceans

Ocean observations showed very warm water at the surface and below, and computer simulations show that these ocean conditions supported intensification despite unfavorable atmospheric conditions.
