Atmospheric mid-latitude circulation is dominated by a zonal, westerly flow. Such a flow is 8 generally symmetric, but it can be occasionally broken up by blocking anticyclones. The subsequent 9 asymmetric flow can persist for several days. In this paper, we apply new mathematical tools based 10 on the computation of an extremal index in order to reexamine the dynamical mechanisms responsible 1...
Abstract Arctic daily warming is gradually garnering the attention of academics. Here we discuss an interdecadal change around mid-1980s in role Central Pacific El Niño-Southern Oscillation (CP ENSO) occurrence frequency events triggered by Atlantic storms winter (called pattern-Arctic rapid tropospheric (A-RTDW) event) and possible mechanism. Before mid-1980s, Niño/La Niña weakened/strengthene...
