Abstract
Parameters of blocking anticyclones (their number, duration and frequency) in the European region, calculated by NCEP/NCAR re-analysis data by seasons for 1948–2012, were analyzed. It is shown that the maximal intensity of blocking anticyclones are observed mainly in winter and spring, and the minimum intensity – in autumn. Their linear trends in 1948–2012 are characterized by positive sign in winterspring period and negative in summer. Change of parameters of blocking anticyclones and air temperature anomalies in the European region associated with two El Nino types (differentiated by spatial and temporal dynamics) are analyzed. Comparison of analyzed El Nino types shows that their manifestations are different significantly by the number of blocking events in autumn-winter, and by the sign of air temperature anomalies in spring-summer
