Global Circulation Animations: Means and Anomalies (Operational Data)
The means and anomalies in the table below are from the NCEP operational dataset. The operational climatology used to produce the anomalies is based on data from 1985-95. During this period, the assimilating general circulation model underwent many changes. An alternative to the NCEP operational dataset is the NCAR/NCEP Reanalysis dataset which has been produced with an unchanging assimilation model. This data is available about 1.5 months after the operational data.
