Arctic weather observations can improve hurricane track forecast accuracy
Comparison of mid-range forecast model accuracy of Atlantic hurricane tracks from 2007 to 2019 revealed that when strong winds associated with upper-level troughs caused hurricanes to move northward, track forecast accuracy was lower. The accuracy of track forecasts in such cases was improved by including data collected over the Arctic Ocean in 2017, by reducing the error in forecasting upper-level troughs. Therefore, additional data collection at high latitudes can improve mid-latitude hurricane track forecasting. (2020-10-08)
