- Air-sea interaction
- Air-land interaction
- Local responses
The linear modelling approach is based on
identification of joint modes of variability linking predictor and
- A subset of CCA pairs representing two fields
is used to build a regression model (Von Storch, 1995) to estimate the
anomalies of predictand (SLP, geopotential height at 500 hPa) from the
anomalies of the predictor (May SST, November air surface temperature).
- The performance of the model is sensitively
dependent on the number of EOFs and CCA pairs used in the regression
- Here, the CCA based models have been been
trained for the interval 1961-1986 and were independently tested in the
interval 1987-2001. Both models use 4 CCA modes derived from 6 EOFs from
the paired fields.
