The climate of China

China is a vast country with diverse climatic patterns. The climate ranges from tropical monsoon in the northeast (Köppen climate classification Am, Aw) to temperate type (Köppen variations of Cw, Cf, Dw, Ds, Df) in the east and south. The northwest is arid (Köppen BSh, BSk), while the high mountains in the west and southwest exhibit a tundra type climate (Köppen ET). China occupies a large part of East Asia and shares borders with fourteen countries on land plus four on water. The latitudes, high mountain ranges, monsoonal rains, and proximity to seas in the east, influence the climate.

China has a diverse topography with high plateaus, snow-capped mountains, rolling plains, broad river valleys, and vast deserts. The southern coasts and eastern plains have the most fertile lands in the country. The north and west have arid lands, massifs, sunken basins, and the highest tableland of Tibet in the world. Eastern China consists of plains in the northeast and north and hills in the south. The Xinjiang-Mongolia region in the northwest contains the vast Taklamakan Desert. The highlands in the west and southwest consist of the world's highest mountain peaks, such as Mount Everest (8848 meters) and K2. Major rivers such has the Yangzte, Yellow, Heilongjiang, Zhujiang, and Liaohe flow from west to east, into the Pacific Ocean. Seas such as the Yellow, East China, and South China are parts of the Pacific Ocean. Shishapangma is the tallest peak to lie entirely in China with a height of 8013 meters in the Tibetan Himalayas.

Summers are hot everywhere in China except for the high mountains and highlands. Winters are cold in the north and mild in the south. Manchuria, the northeast part of China, has hot, rainy summers and frigid, dry winters. July is the hottest, while January is the coldest month of the year. The northwest is arid with hot summers and freezing winters. Turpan is the hottest region in China, with an average high temperature of 40°C (104°F) in July. The mountain ranges in the west, including the Himalayas, Pamir, Karakoram, and the Tian Shan remain cold, even in the summer. The average temperatures on Mount Everest are between -18.9°C (-2°F) to -36.1°C (-33°F) in January. Snowfall occurs through much of winter, and even in the summer. The mountains are relatively warm in the southern province of Yunnan. January average highs register at 15.6°C (60.1°F) at the height of 2000 meters. The southern border with Burma and Vietnam sees heavy rainfall during the hot and humid summers. Winters are very cold in the central region, with average temperatures between -10°C (14°F) to 0°C (32°F) in January. Summer is hot and humid in the capital city of Beijing. The eastern coastal areas have a temperate climate with mild summers and winters. Shanghai receives up to 1168.4mm (46") of rain annually.

The annual rainfall in China ranges from a scarce 254mm (10") in the northwest to more than 1524mm (60") in the southeast. The monsoonal rains arrive during the hot summer, which is the period of the highest humidity. The southeast is the rainiest, while the northwest is the driest region. June to August is the period of the highest rainfall. Precipitation frequently occurs in May and September in many places. Sunshine is ample and registers between 1800 hours to 2800 hours.

A substantial amount of snowfall occurs on the high mountain peaks. Snow is evident in the highlands in the winter but is scarce in the lower plateaus and the lower half of the country.
