Monthly Standardized Velocity Potential Anomaly

This map shows the monthly velocity potental climatology and standardized anomalies at the 250 hPa pressure level in the atmosphere using the 1981-2010 base period for the month shown.

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 standardized velocity potential anomalies are shown in yellow and orange, and negative anomalies are shown in shades of blue, with shading starting at +/-1 standard deviations and a contour interval of 0.5 standard deviations.
