Study on the best way to improve forecasts using a proposed satellite-based Doppler Wind Lidar published in Monthly Weather Review

~ noaahrd ~ 6 Comments

This study investigates how to get the largest improvements to tropical cyclone forecasts from wind profiles obtained from a proposed new instrument, a Doppler Wind Lidar, on polar-orbiting satellites.  Wind profiles have the largest impact when the tropical cyclone’s structure was changing rapidly and when the measurements were taken close to the tropical cyclone center. … Continue reading Study on the best way to improve forecasts using a proposed satellite-based Doppler Wind Lidar published in Monthly Weather Review

Paper on the impact of dropwindsondes from the Global Hawk on forecasts published in Monthly Weather Review

~ noaahrd

Summary:  A drone, what we call an unmanned aircraft system, can collect data in tropical cyclones (TCs) to improve forecasts.  Scientists have used the Global Hawk drone that can fly at an altitude of up to 60,000 feet for over 24 hours at a time since 2010. The Global Hawk releases dropwindsondes that measure wind, … Continue reading Paper on the impact of dropwindsondes from the Global Hawk on forecasts published in Monthly Weather Review

Highlights from the 2014 hurricane season

~ noaahrd

The Atlantic hurricane season will officially end November 30, and will be remembered as a relatively quiet season as was predicted.  Still, the season afforded NOAA scientists with opportunities to produce new forecast products, showcase successful modeling advancements, and conduct research to benefit future forecasts. Despite the quiet Atlantic season, NOAA, and especially HRD, had an … Continue reading Highlights from the 2014 hurricane season
