HOME > Climate & Weather Linkage > Alaska Storm Track Monitoring

Storm tracks are based on an algorithm originally developed at the Earth System Resource Laboratory (ESRL) [Serreze (1995), and Serreze et al. (1997)]. Storm tracks are identified by locating grid points in which the mean sea level pressure (MSLP) is less than its surrounding grid points by at least 1 hPa. The storms are tracked by analyzing the position of systems between time steps and applying a maximum distance threshold between candidate pairings (800 km) and additional other quality control checks. Red/blue dots indicate active storms as of 18 UTC for the respective plot ending date.
