Seasonal Velocity Potential Anomaly

These maps show the seasonal (3-month average) velocity potental climatology and anomalies at the 925 and 250 hPa pressure levels in the atmosphere using the 1991-2020 base period for the season shown.

Seasonal velocity potential climatology values are shown as grey contours with a contour interval of 1.0E+06 m2/s; dashed contours represent negative values and solid contours represent positive values. Positive velocity potential anomalies are shown in yellow and orange, and negative anomalies are shown in shades of blue.
