Plots of Zonal Means: Time Series or Seasonal Cycle

The following form allows you to make plots of either "time series of zonal means" or "seasonal cycle of zonal means".

Note: Depending on your input choices, plots may take 5-10 seconds to generate. Please be patient.

Plot Type:
months
Time Interval:
Base Period:
 

Input Elements

  • Mean period: time series of n-month running mean anomalies are displayed; enter n
  • Time interval: years which are displayed (pick round numbers since they are automatically extended to a multiple of a decade)
  • Base period: time interval to which anomalies are relative

Input Sources

  • Data Sources: Land
  • Data Sources: Ocean
    • None: NO ocean temperature data are used
    • ERSST_v3b: NOAA/NCEI's Extended Reconstructed Sea Surface Temperature (ERSST) v. 3b
    • ERSST_v4: NOAA/NCEI's Extended Reconstructed Sea Surface Temperature (ERSST) v. 4
    • Hadl/Reyn_v2: SST 1880-present -- 1880-11/1981: Hadley HadISST1, ship and buoy data (Rayner 2000); 12/1981-present: OISST v. 2, satellite data (Reynolds-Rayner-Smith 2001)
