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 ...
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 ...
South Africa has typical weather for the Southern Hemisphere, with the coldest days in June–August. On the central plateau, which includes the Free State and Gauteng provinces, the altitude keeps the average temperatures below 20 °C (68 °F); Johannesburg, for example, lies at 1,753 metres (5,751 ft). In winter temperatures can drop below ...
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
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.
The climate is warm in the north, cool in the center, and cold in the southern parts, that experience frequent frost and snow. Because the southern parts of the country are moderated by the surrounding oceans, the cold is less intense and prolonged than areas at similar latitudes in the northern hemisphere. Spring and autumn are transition ...
The average snow to liquid ratio across the contiguous United States is 13:1, meaning 13 inches (330 mm) of snow melts down to 1 inch (25 mm) of water. [11] The El Niño-Southern Oscillation affects the precipitation distribution, by altering rainfall patterns across the West, Midwest, the Southeast, and throughout the tropics. [12] [13] [14] [15]
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.
