Coherent vortices in the vicinity of the tropopause, referred to as tropopause polar vortices (TPVs), may be extracted from high latitudes in conjunction with high-latitude upper-level ridge amplification. Once extracted, TPVs may interact with and strengthen midlatitude jet streams, as well as act as precursor disturbances for the development of intense midlatitude cyclones. Cold pools that may accompany TPVs as they are transported to middle latitudes may lead to widespread cold air outbreaks (CAOs), which may result in significant socioeconomic impacts. The purpose of this study is to investigate 1) the equatorward transport of TPVs and cold pools to middle latitudes and 2) the dynamical linkages between TPVs, cold pools, and CAOs.
