Paper on a new, improved way to get temperature and humidity data from GPS satellites into forecast models released online in Monthly Weather Review

Atmospheric temperature and moisture can be measured accurately using radio signals from any Global Navigation Satellite System (GNSS) like the familiar Global Positioning System (GPS). The process, called “radio occultation,” measures changes in radio signals between satellites as they pass through the atmosphere. When incorporated into computer weather models, these data improve forecasts. However, when … Continue reading Paper on a new, improved way to get temperature and humidity data from GPS satellites into forecast models released online in Monthly Weather Review

HRD participates in American Meteorological Society Annual Meeting

Hurricane Research Division scientists participated in the NOAA 2022 Postseason Aircraft Operations Hotwash at the Aircraft Operations Center in Lakeland, FL, on January 18. Hurricane researchers met with staff from the NOAA's National Hurricane Center, the Environmental Modeling Center, and the Aircraft Operations Center, as well as from the Air Force, to examine both the … Continue reading Scientists participate in post-season aircraft observations meeting

Paper on the importance of radiation in predicting hurricane intensity released online in Geophysical Research Letters

Better prediction of radiative heating in hurricane forecast models leads to better forecasts of tropical cyclone (TC) intensity. This is the first study to evaluate the importance of this radiation effect on TC forecast guidance; we found that better radiation forecasts improve prediction of hurricane intensification and genesis. Tropical cyclones (TCs) behave like heat engines, … Continue reading Paper on the importance of radiation in predicting hurricane intensity released online in Geophysical Research Letters

Study on estimating rain rate in hurricanes published in Geophysical Research Letters

The study significantly reduced the estimated errors and uncertainties of the rain rate by combining observed raindrop size and radar reflectivity using machine learning. Flooding from rainfall is one of the most damaging and deadly hazards associated with tropical cyclones, so estimating rainfall amounts is important to keep people and property safe.  Forecasters use weather … Continue reading Study on estimating rain rate in hurricanes published in Geophysical Research Letters

Study that shows improvements to hurricane models predict how the energy from the ocean transfers to the atmosphere underneath hurricanes released online in Weather and Forecasting

This study examined how changes to the planetary boundary layer (PBL) scheme based on information from large-eddy simulations affected hurricane model forecast performance during the 2021 Atlantic hurricane season. The modified PBL scheme produced more realistic storm structures, on average, when compared to best-track information and observations from Hurricane Hunter Aircraft. The modified PBL physics … Continue reading Study that shows improvements to hurricane models predict how the energy from the ocean transfers to the atmosphere underneath hurricanes released online in Weather and Forecasting

HRD employees recognized at NOAA Research Awards ceremony

NOAA Research held its annual awards ceremony on 7 December virtually, and many HRD employees were recognized. Sim Aberson earned the EEO/Diversity Award for Exemplary Service as part of the OAR Diversity & Inclusion Advisory Committee, for the group's diligent efforts to expand Diversity, Equity, Inclusion, and Accessibility activities and awareness by establishing five working … Continue reading HRD employees recognized at NOAA Research Awards ceremony

NOAA news release about the end of the 2022 hurricane season

"This season, NOAA Hurricane Hunter aircraft flew over 582 mission hours to collect atmospheric data that is critical to hurricane forecasting and research, passing through the eye of a hurricane 65 times and deploying over 1,700 scientific instruments. NOAA’s Gulfstream IV-SP also flew a research mission from Cabo Verde, Africa, in August. This historic mission … Continue reading NOAA news release about the end of the 2022 hurricane season
