Animation of Thirty-Day Average Geopotential Height Anomaly at 250 hPa

This map shows a 90-day animation of thirty-day average geopotential height and anomalies at the 250 hPa pressure level in the atmosphere using the 1981-2010 base period.

Thirty-day average geopotential height values are shown as grey contours with a contour interval of 75 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.
