The concurrence of atmospheric rivers and explosive cyclogenesis in the North Atlantic and North Pacific basins
Abstract. The explosive cyclogenesis of extratropical cyclones and the occurrence of atmospheric rivers are characteristic features of a baroclinic atmosphere, and are both closely related to extreme hydrometeorological events in the mid-latitudes, particularly on coastal areas on the western side o...
