AUTOREGRESSION ESTIMATES OF THE RELATION BETWEEN SURFACE AIR TEMPERATURE FIELDS AND LARGE-SCALE ATMOSPHERIC CIRCULATION

E. A. Rybak and O. O. Rybak

The relation between atmospheric circulation features and the surface air temperature field is considered in the context of global climate change. One- and two-dimensional autoregression analysis is used to analyze observational time series. The time series of temperature and circulation patterns contain a statistically significant linear trend. The estimates of correlation and spectral characteristics give insight into some general features of variability of climatic parameters.
