A 2007 estimate of snow cover over the Northern Hemisphere suggested that, on average, snow cover ranges from a minimum extent of 2 million square kilometres (0.77 × 10 ^ 6 sq mi) each August to a maximum extent of 45 million square kilometres (17 × 10 ^ 6 sq mi) each January or nearly half of the land surface in that hemisphere.

Accumulations of snow and ice are commonly associated with winter in the Northern Hemisphere, due to the large land masses there. In the Southern Hemisphere, the more maritime climate and the relative lack of land south of 40°S make the winters milder; thus, snow and ice are less common in inhabited regions of the Southern Hemisphere.
The glaciations that occurred during the glacial period covered many areas of the Northern Hemisphere. Northern hemisphere glaciation during the last ice ages. The setup of 3 to 4 kilometer thick ice sheets caused a sea level lowering of about 120 m. The Arctic is a region around the North Pole (90° latitude). Its climate is characterized by ...
During these early months of Northern Hemisphere spring most of the Arctic is still experiencing winter conditions, but with the addition of sunlight. The continued low temperatures, and the persisting white snow cover, mean that this additional energy reaching the Arctic from the sun is slow to have a significant impact because it is mostly ...
At 4:20 a.m. ET, the solstice will take place, marking "the beginning of winter in the Northern Hemisphere and summer in the Southern Hemisphere," according to NASA.
Because Christmas occurs during the summer in the Southern Hemisphere, white Christmases are especially rare events there, apart from Antarctica, which is generally uninhabited. A white Christmas elsewhere in the Southern Hemisphere is approximately equivalent to having snow in the Northern Hemisphere on 25 June.
Visualization of the ice and snow covering Earth's northern and southern polar regions Northern Hemisphere permafrost (permanently frozen ground) in purple. The polar regions, also called the frigid zones or polar zones, of Earth are Earth's polar ice caps, the regions of the planet that surround its geographical poles (the North and South Poles), lying within the polar circles.
Lake effect snow is forecast to wallop the already snow-buried Great Lakes region, ... Parts of Pennsylvania could get hit with 6 to 15 inches of snow in Northern Erie and South Erie.
