  1. located 45 to 55 degrees north.
  2. cyclonic storms near polar.

Location that differs and why

The southern hemisphere doesn't have any DWB regions, because the southern hemisphere has no large landmasses in its middle latitudes. So, it does not allow hot summers with one month of sub-freezing temperatures.

In south east Siberia, ther is also a Dwc region. It differs from the Dwb region because it has a more cold and short summer, while the Dwb region has a moderate summer.

Floral/Faunal adaption

Couple of the Floral and Faunal adaptions include:

  • Fur coats that are shed during the summer and grow in the winter
  • Conifer trees have needles so it doesn't lose as much water
