The cool summer subtype is marked by mild summers, long cold winters and less precipitation than the hot summer subtype; however, short periods of extreme heat are not uncommon. Northern Japan has a similar climate.
Dwa = Monsoon-influenced hot-summer humid continental climate; coldest month averaging below 0 C (32 F) (or −3 C (27 F)), at least one month's average temperature above 22 C (71.6 F), and at least four months averaging above 10 C (50 F).
  Regions where the continental climates (Dfa, Dfb, Dfc, Dfd) are found. Dfa = Hot-summer humid continental climate; coldest month averaging below 0 °C (32 °F) (or −3 °C (27 °F)), at least one month's average temperature above 22 °C (71.6 °F), and at least four months averaging above 10 °C (50 °F).
A humid continental climate is marked by variable weather patterns and a large seasonal temperature variance, cold and often very snowy winters, and warm summers. Places with more than three months of average daily temperatures above 10 °C (50 °F) and a coldest month temperature below −3 °C (27 °F) and which do not meet the criteria for ...
It may refer to: Humid continental climate (Köppen Dfa/b), a climatic type typified by four distinct seasons and large seasonal temperature differences Humid subtropical climate (Köppen Cfa), a zone of climate characterized by hot and humid summers, and cool to mild winters Equatorial or tropical rainforest climate. (Köppen Af).
A humid subtropical climate is a temperate climate type characterized by hot and humid summers, and cool to mild winters. These climates normally lie on the southeast side of all continents (except Antarctica), generally between latitudes 25° and 40° and are located poleward from adjacent tropical climates.
The cool summer subtype is characterized by mild summers (no month averaging over 22 C), cold winters and less precipitation than the hot summer sub-type. Mean temperatures range from -24 °C (January) to +25 °C (August). Average annual precipitation is 390 mm. Flora and fauna
