Why are there no severe-winter climates in the southern hemisphere?

Answer 1

From Wikipedia:

"GROUP D: Continental/microthermal climate
These climates have an average temperature above 10 °C in their warmest months, and a coldest month average below −3 °C (or 0 °C in some versions, as noted previously). These usually occur in the interiors of continents, or on their east coasts, north of 40° North latitude. In the Southern Hemisphere, Group D climates are extremely rare due to the smaller land masses in the middle latitudes and the almost complete absence of land between masses south of 40° South latitude, existing only in some highland locations in New Zealand that get heavy winter snows."

Answer 2

Because most of the land masses in the South are closer to the Equator than in the North.

Answer 3

There are. As you get further from the equator the severity of the winters increases.

Answer 4

There are. Visit Tierra del Fuego in Chile. It's probably the worst-named area on the planet.

Answer 5

There is, it's called Antarctica.
