摘要：

We quantified the seasonal/regional patterns and changes in cyclone activity in the atmosphere of the Northern Hemisphere and determined the contribution of extratropical cyclones to the formation of corresponding patterns and precipitation changes. It is ascertained that the contribution of extratropical cyclones to the total amount of precipitation exceeds 60% on the whole; for regions with a high cyclone frequency, it attains 75% in winter and 65% in summer. Intense cyclones contribute the most: 60% in winter and 35% in summer.
