Physico-statistical method of decomposition of hydrometeorological fields and its comparison with the method of empirical orthogonal functions
The article describes two methods of fields decomposition - the physico-statistical method and EOF as exemplified by air temperature fields. The results of decomposition of space-time series of mean monthly air temperature are presented for the period 1886 - 2004 for 116 stations over the territory of the former USSR. The advantage of using the physico-statistical method in comparison with the EOF decomposition method is shown.
