Climate
China is situated in the eastern part of the Asian Continent,
facing the Pacific, the world's largest ocean, thus having a
prominent monsoon climate. It also sees various other types of
climate due to its vast territory, complicated topography and a
great disparity in elevation. Climate zones from south to north
appear in this order: tropical zone, subtropical zone, temperate
zone, medium temperate zone and frigid temperate zone. There is
also a vertical climatic zone on the Qinghai-Tibet Plateau.
Temperature
The Mohe area of Heilongjiang Province at the northernmost tip
of China, located north of Latitude 53°N, has a frigid temperate
climate. Zengmu Ansha in Hainan Province at the southern end, only
400 km from the equator, is dominated by the equatorial climate.
Thus, there is great temperature difference between the south and
the north.
In winter, most areas in China are cold and the temperature
varies greatly between northern and southern parts. In Mohe, the
temperature in January averages -30℃, while that in Sanya, Hainan,
is above 20℃.
In summer, the days are long in the northern part because the
sun is directly over the Northern Hemisphere at this time. The
northern areas get almost as much heat from sunlight as the
southern part. Therefore, the temperature is high nationwide,
except for the Qinghai-Tibet Plateau with an exceptional elevation,
and temperature difference is small between the north and the
south.
Precipitation
Influenced by the oceanic warm and humid air current, most areas
in China have rich rainfall. But the rainfall is unevenly
distributed both regionally and seasonally. The east has more rain
than the west and rainfall is concentrated in the summer. The rainy
season in the south is long, lasting from May to October, while
that in the north is short, spanning July and August. The amount of
precipitation differs greatly from year to year, with some years
having more rainfalls than others.
Sunshine
Most parts of China are located north of the Tropic of Cancer.
In winter, the incident angle of the sunlight is small, resulting
in short duration of sunshine. Therefore, the amount of heat from
sunshine is comparatively small in these regions, decreasing
further north one goes. In summer, these regions have more heat
from sunlight with long days because the sun's rays directly
radiate on the Northern Hemisphere in this season.
