Dwb climate

The Dwb climate, a subtype of the humid continental climate, is characterized by large seasonal temperature variations, featuring hot summers and cold winters. This climate is primarily found in the Northern Hemisphere, specifically in central and eastern North America and Asia, between approximately 30° and 60° N latitude. It is a region where polar and tropical air masses frequently interact.1

A key feature of the Dwb climate, particularly in eastern Asia, is its monsoonal variant. This means it experiences a distinct precipitation maximum during the summer months, often due to convective showers when warm, moist tropical air moves northward. Conversely, winters are cold and dry, heavily influenced by dry, continental polar air masses originating from nearby anticyclones. Precipitation in these regions is generally ample throughout the year, with winter precipitation often falling as snow, which can accumulate for several months. Annual temperature ranges in these climates are significant.12
