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 […]
