Regional extrapolation of meteorological data in a distributed hydrological model

The following tasks are considered: (a) obtaining the regional dependencies for climatic norms of air temperature, precipitation and humidity as functions of altitude, latitude and longitude; (b) preparing a regional information database; and (c) developing a method of extrapolation of longterm series of temperature, precipitation and humidity measurements on a basic network into arbitrary points in the Central Asian region. The estimated quality of computed long-term series of precipitation, humidity and air temperature at fourteen control points turned out to be satisfactory.
