CIMAS celebrates its achievements with awards ceremony

The Cooperative Institute for Marine and Atmospheric Studies, a NOAA Center of Excellence responsible for carrying out much of the basic research in NOAA, held an awards ceremony on 11 February to celebrate individual and group accomplishments during the past year and a half. About half of those who work inside the AOML building on … Continue reading CIMAS celebrates its achievements with awards ceremony

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

HRD scientists participate in the 101st American Meteorological Society Annual Meeting

Paper on the accuracy of an experimental airborne instrument to measure temperature and humidity published in Atmospheric and Oceanic Technology

The Global Hawk, a drone or autonomous aircraft system, has been used since 2010 to gather data to improve weather forecasts. The Global Hawk releases dropsondes that measure temperature, pressure, humidity, and wind up to four times every second between 60,000 feet and the surface, providing thousands of measurements. The Global Hawk also has the … Continue reading Paper on the accuracy of an experimental airborne instrument to measure temperature and humidity published in Atmospheric and Oceanic Technology

Paper on forecasting how raindrops, snowflakes, and ice form, grow, and fall released online in Monthly Weather Review

Summary:  Tropical cyclones (TCs) are made up of clouds and thunderstorms, and thus drop large amounts of rain. The clouds are made up of cloud particles such as raindrops, snowflakes, and ice.  Knowledge of the ways these particles form, grow, and fall (what we call cloud microphysics) is very important for accurate TC rainfall forecasts, … Continue reading Paper on forecasting how raindrops, snowflakes, and ice form, grow, and fall released online in Monthly Weather Review
