The SMH has been weakening in recent decades, which appears to correlate with the negative phase of NAO/AO due to increased warm air advection over the Eurasian continent and the resultant reduction in snow cover. However, it is not clear that this recent decrease in the EAWM intensity is unique in the most recent 400 years. Periodical cold air outbreaks that cause high-impact weather are associated with the intra seasonal and synoptic variation of the SMH, and they often continue as cold monsoonal surges into the tropics and affect the tropical component of the EAWM. There is some evidence that intraseasonal variability has decreased in 1990s although extreme weather events in the past few years counter this trend. An important mechanism for the intraseasonal and higher frequency enhancement of the SMH comes from upper level blocking ridges over the Atlantic and the Pacific. The Atlantic blocking triggers a Rossby wave train that has a downstream effect of enhancing the SMH. The Pacific blocking forces the SMH through slow retrogression of the blocking center.
