A regional hurricane model is used to conduct the most comprehensive assessment of the impact of dropsondes on tropical cyclone (TC) forecasts to date. Dropsonde data can improve many aspects of TC forecasts if they are assimilated with sufficiently advanced techniques. Particularly notable is the impact of dropsonde data on TC-significant-wind-radii forecasts, since improving those […]

Evaluating the impact of observing systems, new modeling systems, or model upgrades on forecasts of tropical cyclones (TCs) is vital to ensure optimal forecast improvements. Differences between observations (what really happened) and forecasts are calculated and are called forecast errors. Historically, analyzing these errors involved just looking at average errors. Yet doing so can lead […]
