イベント概要 講演者 Paul Prikryl ( University of New Brunswick, Canada )
要旨 Wilcox effect, a relation between solar wind magnetic sector boundary structure and mid-latitude upper tropospheric vorticity [1], was confirmed [2] pointing to a possibility that coupling between the solar wind and the Earth’s magnetosphere, and ultimately the ionized and neutral atmosphere, can influence development of tropospheric weather [3,4,5]. It is observed that explosive extratropical cyclones and rapid intensification of tropical cyclones, tend to follow arrivals of high-speed solar wind streams from coronal holes or coronal mass ejections, when large amplitude magneto-hydrodynamic waves couple to the magnetosphere-ionosphere-atmosphere (MIA) system generating sources of medium-scale atmospheric gravity waves in the lower thermosphere at high latitudes.
