What are the highest and lowest temperatures in summer and winter in China?

The highest summer temperature in China occurs in Turpan Basin, Xinjiang, with an average temperature of 32.7℃ and an extreme temperature of 49.6℃ in July.

The lowest temperature in winter in China appears in Mohe, Heilongjiang, with a monthly average temperature of -30.9℃, 1 monthly extreme temperature of -52.3℃.

In China, the absolute maximum temperature appeared in Turpan, Xinjiang Uygur Autonomous Region, reaching 48.9℃. The absolute minimum temperature of Mohe River in Heilongjiang Province is-52.3 degrees Celsius.

The aperiodic change of temperature is always influenced by atmospheric movement, so sometimes the actual change of temperature is not as simple as the periodic change mentioned above.

For example, in the south of China, after March, it is the season of warm spring in bloom, but it often turns cold suddenly because of the activity of cold air. In autumn, when the air is crisp in autumn, it often suddenly warms up because of the arrival of warm air.

Extended data:

The temperature is influenced by the following human factors:

1, the influence of the characteristics of urban underlying surface (the contact surface between atmospheric bottom and surface)

A large number of artificial structures in the city, such as paving the ground and various building walls, have changed the thermal properties of the underlying surface. Urban surface water content is less, and more heat enters the air in the form of sensible heat, which leads to air warming. At the same time, the absorption rate of sunlight on the urban surface is higher than that on the natural surface, which can absorb more solar radiation, so that the air can get more heat and the temperature will rise.

2. Urban air pollution

Motor vehicles, industrial production and a large number of people's activities in cities produce a lot of nitrogen oxides, carbon dioxide, dust and so on, which can absorb a lot of energy from the thermal radiation in the environment, produce a well-known greenhouse effect, and cause further warming of the atmosphere.

3, the influence of artificial heat source

Factories, motor vehicles, residents' lives, etc. Burning all kinds of fuels consumes a lot of energy and countless stoves are burning and emitting heat.
