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. In this region, snow occurs every year in elevated regions such as the Andes, the Great Dividing Range in Australia, and the mountains of ...
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.
In the Northern Hemisphere the snow line on the north-facing slopes is at a lower elevation, as the north-facing slopes receive less sunlight (solar irradiance) than south-facing slopes. [3] The converse will occur in the Southern Hemisphere.
The most snow in a season in New Orleans is only 2.7 inches, which took place in 1963-64. In Houston, the highest seasonal snowfall total is 4.8 inches in 1973-73. 4) Don't Forget the Ice
s: A dry summer—the driest month in the high-sun half of the year (April to September in the Northern Hemisphere, October to March in the Southern Hemisphere) has less than 30 millimetres (1.18 in)/40 millimetres (1.57 in) of rainfall and has exactly or less than 1 ⁄ 3 the precipitation of the wettest month in the low-sun half of the year ...
Snow accumulation on ground and in tree branches in Germany Snow blowing across a highway in Canada Spring snow on a mountain in France. Classifications of snow describe and categorize the attributes of snow-generating weather events, including the individual crystals both in the air and on the ground, and the deposited snow pack as it changes over time.
Some parts of the Arctic are covered by ice (sea ice, glacial ice, or snow) year-round, especially at the most poleward parts; and nearly all parts of the Arctic experience long periods with some form of ice or snow on the surface. Average January temperatures range from about −40 to 0 °C (−40 to 32 °F), and winter temperatures can drop ...
In Australia, the polar vortex, known there as a "polar blast" or "polar plunge", is a cold front that drags air from Antarctica which brings rain showers, snow (typically inland, with blizzards occurring in the highlands), gusty icy winds, and hail in the south-eastern parts of the country, such as in Victoria, Tasmania, the southeast coast of ...
