Storm tracks are based on an algorithm developed at the Climate Diagnostics Center (CDC) [Serreze (1995), and Serreze et al. (1997)]. Storm tracks are identified by locating grid points in which the sea level pressure (SLP) is less than its surrounding grid points. The threshold used here is 1 mb. 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.

Storm tracks for the past 10, 30, and 90 days. Fields of total precipitation, low-level vector wind anomalies, ocean wave heights, and sea ice are also included with the storm tracks for reference. In addition, cyclogenesis/cyclolysis locations are displayed. |
