Paper on the impact of new satellite wind velocity data on hurricane forecasts published in Monthly Weather Review

Summary: The CYclone Global Navigation Satellite System (CYGNSS) was launched into space on December 15, 2016, to improve hurricane (tropical cyclone) forecasts by measuring wind speed on the ocean surface. Since the tropical cyclones mostly occur over oceans where other wind data are usually not available, the new observations can measure their wind speeds. This …

Paper on calculating and using wind speed and direction from the new NASA CYclone Global Navigation Satellite System (CYGNSS) released online in the Journal of Atmospheric and Oceanic Technology

Summary:  The NASA CYclone Global Navigation Satellite System (CYGNSS) measures wind speed, but not direction, at the ocean surface. To test the impact of new observations before such a satellite system is launched, observations like those from the satellite are created from a weather model. This study uses these “simulated” observations to learn how to …

Paper on the best way to input very large numbers of observations into weather models published in Monthly Weather Review

Summary: Almost all weather forecasts for times longer than a few hours in the future are made using complicated computer apps working together on the largest computers. This is known as numerical weather prediction, or NWP for short. One of the most important NWP apps takes all kinds of data and mixes them together to …
