Standardized Change in Sea Surface Temperature (SST) Anomaly from Previous Month

Data:   Monthly sea surface temperature anomaly (deg. C) on a 1.0 x 1.0 deg. lat/lon grid (1950-present) Base Period for Climatology:  1951-1980 Base Period for Standardization:  1950-present Data Source: Kaplan v2 Description:  Change in sea surface temperature anomaly from the previous month divided by (standardized) the standard deviation of change for the given month over the base period indicated. Contours drawn at intervals of 0.5 starting at +/- 1. Shading starts at +/- 1 standard deviation.
