Monthly Geopotential Height Anomaly at 500 hPa

This map shows the monthly geopotential height climatology and anomalies at the 500 hPa pressure level in the atmosphere using the 1981-2010 base period for the month shown.

Monthly geopotential height climatology values are shown as grey contours with a contour interval of 60 geopotential meters (gpm). Positive geopotential height anomalies are shown in yellow and orange, and negative anomalies are shown in shades of blue and are also expressed in units of gpm.
