Abstract

The global meteorological observing system is extremely expensive and in the present economical situation some conventional observations such as radiosondes begin to be severely reduced. At the same time improved satellite systems become available (Kondratyev et al., 1996). The operational observing network, which uses both conventional and satellite measurements, influences the weather forecast accuracy through the initial atmospheric state uncertainty (Beliavsky and Pokrovsky, 1983; Ghil et al., 1979; Pokrovsky, 1984; Pokrovsky, 2000). Therefore, there is an urgent necessity to investigate the importance of different observing subsystems on numerical weather forecasting performance (Epstein, 1969; Kondratyev et ai, 1996; Pokrovsky and Denisov, 1985).
