Map source

The online map of average annual cold wave frequency 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.

Map description

In the high latitude area of the cold wave, strong cold air explodes southward, and weather such as severe temperature drop, strong wind, and thunderstorm occurs in the place it passes. When the temperature drop and the extreme minimum temperature reach a certain standard, it is called a cold wave. Strong cooling and strong winds often cause crops, fruit trees, vegetables, etc. to suffer low temperature and freezing damage and snow disasters, boats blow over, trees uprooted, houses damaged, and people's lives and property suffer losses. The frequency distribution of annual cold wave in China is characterized by more in the north and less in the south. The frequency of cold wave in Northeast China, the West and north of North China, the north and central part of Northwest China, most of Tibet and Inner Mongolia is more than 4 times a year on average. Among them, there are generally 10 ~ 15 times in some areas in the East and north of Northeast China, most of Inner Mongolia and Northern Xinyi, and more than 15 times in some areas.
