Association of the Zonal Migration of North Pacific Storm Track With the East Asian Monsoon in Boreal Wintertime

Abstract

The change in atmospheric circulation in the midlatitudes is manifested as a conspicuous synoptic-scale disturbance, which is associated with the formation, evolution, and dissipation of daily weather systems. Located in areas where cyclones, anticyclones, and baroclinic waves occur frequently (Penny et al., 2013), the storm track refers to the region where the maximum variance of synoptic-scale (2.5-6 days) disturbance occurs (Blackmon, 1976; Blackmon et al., 1977) and indicates the synoptic-scale transient wave itself, which is called the "baroclinic waveguide" (Wallace et al., 1988). The storm track redistributes heat, moisture, and angular momentum (Mbengue & Schneider, 2018), helping to maintain the global temperature distribution and the basic characteristics of atmospheric circulation, as well as playing an important role in modulating extreme weather events in the midlatitudes (

The Guiding Role of Rossby Wave Energy Dispersion Theory for Studying East Asian Monsoon System Dynamics

“…The results show that the variabilities of the East Asian winter and summer monsoon systems are the variablities of circulation seeing from their phenomena, but these variabilities are also the variations of quasi-stationary planetary waves according to their mechanisms. Currently, this theory is developing and expanding, and it has wide applications not only in the study on atmospheric circulation dynamics at middle and high latitudes but also in the study on the dynamics of typhoon genesis and evolution in tropical regions [46][47][48][49][50][51]. Moreover, the nonlinear effects of the energy dispersion of Rossby wave in atmosphere and the nonlinear interactions of different quasi-stationary planetary wave trains also need to be further investigated.…”
