Abstract: he frequencies of atmospheric blocking in both winter and summer and the changes in them from the twentieth to the twenty-first centuries as simulated in 12 models from phase 5 of the Coupled Model Intercomparison Project ...

Abstract: his paper generalizes and applies recently developed blocking diagnostics in a two-dimensional (2D) latitude?longitude context, which takes into consideration both mid- and high-latitude blocking. These diagnostics identify ...

Abstract: The frequency of persistent atmospheric blocking events in the 40-yr ECMWF Re-Analysis (ERA-40) is compared with the blocking frequency produced by a simple first-order Markov model designed to predict the time evolution ...
