Weekly OLR Anomaly

This map shows weekly outgoing longwave radiation anomalies for the globe.

This map shows weekly outgoing longwave radiation (OLR) anomalies in units of Watts/m2. The period used for computing the climatology is 1991-present. Negative anomalies in green on the map imply increased cloudiness and enhanced likelihood of precipitation. Positive anomalies in brown imply decreased cloudiness and precipitation. The relationship between OLR anomaly and precipitation is most reliable in tropical regions.

These data are from the NOAA NCEP Climate Prediction Center.
