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

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, …

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 …

HRD Seminar – Dr. Michael Vellinga, Met Office, United Kingdom – 12 March 2018

Dr. Vellinga presented a seminar titled “The impact for tropical storm forecasts of upgrades to UK Met Office prediction systems”. Abstract The past two years have seen various upgrades to the UK Met Office's operational prediction systems, including a near-doubling of horizontal resolution in the global deterministic forecast model to 10 x 12km. I will …
