METHODOLOGY OF REGIONAL METEOROLOGICAL NETWORK RATIONALIZATION

O. M. Pokrovskii

Aspects of rationalization of regional meteorological networks are considered. A general methodology is discussed, including the following main stages of the practical solution of the problem: statistical regionalizing of the area covered by a Hydrometeorological Service Department (HSD), selecting information-homogeneous zones (IHZ), estimating informativeness of IHZ and of observation points (OP), and developing minimum and sufficient networks. Expressions are obtained for the response functions used for numerical solution of the optimization problems. As an illustration, optimization of the network in the Kamchatka HSD is proposed, with results for the main stages of solution. Maps are presented of the HSD area regionalizing. Schemes are given for minimum and sufficient observation networks. The priority stations are taken into account.
