On June 1922+10/October 16, 2006, -50. 1℃ was observed crossing the river in Miandu, Daxinganling, Inner Mongolia Autonomous Region. It is the lowest temperature recorded before the founding of New China. After the founding of New China, Fuyun Meteorological Station in northern Xinjiang broke the record of crossing the river at a low temperature of -50.7℃ for the first time on 19601October 20th, and then set a new national record at 65438+2 1.5℃ on1October 20th. The northernmost weather station in China, Mohe weather station in Heilongjiang Province, measured a temperature of -50.9℃ on the morning of February 27th. 1February, 969 13, Mohe finally gave birth to the extreme lowest temperature record in the existing meteorological data in China-52.3℃.
Extended data
The temperature in a certain place changes periodically not only because of the change of solar radiation, but also because of the movement of the atmosphere rather than periodically. The change of actual temperature is the result of the joint action of these two aspects. If the former plays a big role, the temperature changes periodically; On the contrary, it shows an aperiodic change.
However, from the general trend and most cases, the periodicity of daily and annual temperature changes is still the main one. Various components in the heat balance, such as radiation difference, latent heat and sensible heat exchange, are affected by different control factors. Astronomical factors such as latitude and season have obvious zonal and periodic characteristics.
However, the nature, topography and weather conditions of the underlying surface, such as cloud cover and atmospheric humidity, all have non-zonal characteristics. At the same time, the influence of these factors is different in different places, so the temperature distribution caused by the change of heat budget is also uneven.
