Global Circulation Means and Anomalies (Operational Data)
Plot update date is: Monday, 10-Nov-2025 12:00:05 MST
The means and anomalies in the table below are from the NCEP operational dataset. The operational climatology used to produce the anomalies is now based on data from 1991-2010. During this period, the assimilating general circulation model underwent many changes.
FORMAT:
- (1) Mean and Anomaly plots are combined into ONE Two-panel plots.
- (2) The One-panel mean and anomaly plots are available and accessible from the Two-panel web pages.
