Monthly Velocity Potential Anomaly

This map shows the monthly velocity potential climatology and anomalies at the 925 and 250 hPa pressure levels in the atmosphere for the given month over the 1991-2020 base period.

Monthly 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 and are also expressed in units of m2/s.
