Persistent Circulation Regimes and Preferred Regime Transitions in the North Atlantic

Abstract:

The persistent regime behavior of the eddy-driven jet stream over the North Atlantic is investigated. The North Atlantic jet stream variability is characterized by the latitude of the maximumlower tropospheric wind speed of the 40-yrECMWFRe-Analysis (ERA-40) data for the period 1 December 1957-28 February 2002. A hidden Markov model (HMM) analysis reveals that the jet stream exhibits three persistent regimes that correspond to northern, southern, and central jet states. The regime states are ...
