Abstract:

Separation of principal components characterized by a long-term climate dynamics and their application to diagnostics and prognosis is considered. Principal factors are multicomponent 4D (space and time) constructions. They are calculated based on many-year data on the climatic system behavior and sensitivity characteristics using factor analysis algorithms. Reanalysis NCEP/NCAR 40-year database is invoked into calculations. Two types of principal components of global and regional scale are constructed. The results of comparative analysis of their information quality are given. The principles of construction of climatic and ecological scenarios with the use of databases, factor solutions, and numerical models of the processes under study are formulated.
