The online map of average annual high temperature days in China from 1981 to 2010 comes from China Severe Weather and Climate Atlas (1961-2015). This atlas is compiled by the National Climate Center and published by the meteorological publishing house.
This atlas is compiled based on the statistics of national meteorological observation data, including 16 kinds of disastrous weather and climate graphic analysis products affecting China, including typhoon, rain and waterlogging, snow disaster, cold wave, gale, sandstorm, low temperature and cold damage, high temperature, drought, lightning, hail, frost, freezing, fog, haze and acid rain, such as the spatial distribution map of annual and seasonal occurrence frequency, the spatial distribution map of certain characteristic values, the national and regional frequency of the changes over the years (1961-2015), the national and regional frequency of the monthly changes, etc., a total of more than 300 Width.
In addition, the disaster information change maps of major meteorological disasters such as typhoon, rain and waterlogging, low-temperature freezing damage and snow disaster, drought, lightning and hail are compiled, and individual cases of major historical disaster events such as typhoon, rain and waterlogging, sandstorm, low-temperature freezing damage and snow disaster, high temperature and drought are selected. In order to facilitate readers' reading and comprehension, this atlas not only provides a large number of intuitive graphics, but also provides text descriptions of the main features.
This atlas is a reference book for understanding China's disastrous weather and climate. It can be used by business, scientific research, teaching and other personnel in the fields of meteorology, agriculture, water conservancy, geography, education, environment, land and resources, as well as by relevant departments such as disaster prevention and reduction, construction planning and so on.
The daily maximum temperature is defined as high temperature day in high temperature meteorology; The daily maximum temperature ≥ 38 ℃ is called a very hot day. A high-temperature process is defined as a high-temperature process, also known as high-temperature heat wave, when the maximum temperature ≥ 35 ℃ for 3 consecutive days or more or ≥ 35 ℃ for 2 consecutive days and ≥ 38 ℃ for one day. Continuous high temperature has a certain impact on people's daily life and health; It will also intensify water evaporation and crop transpiration and accelerate the development of drought; This has led to a sharp increase in the demand for hydropower and a shortage of energy supply.
There are two high value areas for annual high temperature days in China: one is located in Jiangnan, northern South China, Northern Hainan, Chongqing and other places, generally 20-30 days, and more than 30 days in some areas; The other is located in southern Xinjiang, Junggar Basin and Western Inner Mongolia for 30-50 days, and Turpan Basin for more than 50 days.
