SHA and SHR

Sea Height Anomaly (SHA)

The figures below show the weekly and monthly SHA (upper and middle plots, respectively) in the El Niño Southern Oscilation 1.2 (ENSO 1.2). The details of the monthly SHA for the last 3 to 4 years are shown in the lower panel. Each bar in the plots represent the mean SHA in the corresponding week (upper figure) or month (middle and lower plots). The SHA data in these figures are referenced to the 1993-1999 mean.

These time series are updated monthly.

Sea Height Residuals (SHR)

The figures below show the weekly and monthly SHR (upper and middle plots, respectively) in the El Niño Southern Oscilation 1.2 (ENSO 1.2). The details of the monthly SHR for the last 3 to 4 years are shown in the lower panel. The monthly SHR for each month is the difference between the mean SHA for that specific month and the mean SHA value for that month since October 1992.

These time series are updated monthly.
