A better way to get GPS radio occultation into forecast models published in Monthly Weather Review

■ Summary:  The Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC) are a set of satellites launched in 2006 that orbit the earth about 500 miles above ground.  They use radio signals from Global Positioning System (GPS) satellites in a process called “radio occultation” to measure temperature and moisture with high accuracy.  These data … Continue reading A better way to get GPS radio occultation into forecast models published in Monthly Weather Review

AOML Hurricane Scientists Facilitate Leap in Hurricane Modeling and Prediction Systems

Hurricane scientists at NOAA’s Atlantic Oceanographic and Meteorological Laboratory have created a new, advanced moving nest system within the Unified Forecast System, the bedrock of NOAA’s weather prediction applications.  AOML’s Hurricane Modeling and Prediction Team developed the high-resolution moving nest for the FV3 dynamical core, laying the foundation for next-generation advancements in hurricane forecasting. HAFS forecast showing Hurricane … Continue reading AOML Hurricane Scientists Facilitate Leap in Hurricane Modeling and Prediction Systems

Paper about how a new forecast model for hurricanes performed during 2019 released online in Weather and Forecasting

This paper summarizes forecasts from an experimental forecast model called the Hurricane Analysis and Forecast System (HAFS) made during the 2019 Hurricane Season. HAFS is being developed for future use as an operational hurricane model to help forecasters predict what a hurricane is going to do. HAFS forecasts the weather on a set of points … Continue reading Paper about how a new forecast model for hurricanes performed during 2019 released online in Weather and Forecasting

Study on the rapid intensification of Hurricane Dorian near the Eastern Caribbean published in Atmosphere

Summary:  We look at why Hurricane Dorian was able to intensify in the Eastern Caribbean when many forecasts suggested that it would stay weak and perhaps die out. To help answer this question, we use a forecast model called the Hurricane Analysis and Forecast System (HAFS).  Specifically, we use an ensemble, a group of forecasts … Continue reading Study on the rapid intensification of Hurricane Dorian near the Eastern Caribbean published in Atmosphere

Paper on the relationship between African dust and hurricane activity published in Atmospheric Chemistry and Physics

Dust layer associated with the Saharan Air Layer.  Photo taken from the NOAA G-IV northeast of Barbados during a Saharan Air Layer Experiment mission into Hurricane Helene on Sep 16, 2006.  Small cumulus clouds can be seen poking through the tops of the dust layer, which is seen as a milky white haze.  Photo credit: … Continue reading Paper on the relationship between African dust and hurricane activity published in Atmospheric Chemistry and Physics

HRD Scientists participate in 2020 Hurricane Forecast Improvement Project Annual Meeting

The 2020 HFIP Annual Meeting was held virtually from 17-19 November. The primary objective of the meeting was to discuss the key HFIP strategies as documented in the HFIP Strategic plan, including development of the next-generation Hurricane Analysis and Forecast System (HAFS) within NOAA's Unified Forecast System. The current state of operational hurricane modeling capabilities … Continue reading HRD Scientists participate in 2020 Hurricane Forecast Improvement Project Annual Meeting

Rob Rogers participates in the 2020 HIWeather Workshop

HIWeather is a World Meteorological Organisation research project, developing warning capabilities for weather-related hazards, to increase resilience worldwide. HIWeather participants form an international network of scientists, in a wide variety of disciplines, all concerned with aspects of the production and communication of weather-related warnings.  The workshop is aimed at anyone interested in improving weather-related warnings, … Continue reading Rob Rogers participates in the 2020 HIWeather Workshop
