Seasonal Standardized Geopotential Height Anomaly

These maps show the seasonal geopotential height climatology and standardized anomalies at the 250, 500, and 925 hPa pressure levels in the atmosphere using the 1991-2020 base period for the season shown.

Seasonal geopotential height climatology values are shown as grey contours with a contour interval of 60 geopotential meters (gpm). Positive standardized geopotential height 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.
