Selection of representative stations by means of a cluster analysis for the BAMAR region in the PIDCAP period

A cluster analysis procedure is presented that allows to select stations that are typical for different meteorological conditions. The estimations of mean daily minimum and maximum air temperatures, and also mean daily precipitation were used as parameters of the classification procedure. The means are calculated using verified synoptic data which are collected in the course of interval from August to October 1995 at 950 synoptic sites allocated on the Baltex Model Area (BAMAR) region. As a result 83 representative stations are selected, and used for validation of the LM-model at PIK.
