Map source

The online map of the average number of cold damage processes of rice in spring in southern 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

Low temperature chilling injury refers to the occurrence of one or more low-temperature weather processes during crop growth and development, resulting in the delay of crop growth period or the obstruction of physiological activities. In serious cases, some tissues are damaged, resulting in the reduction of crop yield and quality.

Low temperature and chilling injury of rice in spring refers to one or more low-temperature weather processes during the sowing and planting period of early rice along the Yangtze River and its south, resulting in a large area of rotten seedlings and dead seedlings. The number of cold injury processes in spring in Hunan, Hubei, Northwest Jiangxi, Fujian and northern Guangdong is generally more than 1.0 times, and more than 1.5 times in some areas; Most of South China and Eastern Jiangnan are less than 1.0 times, including less than 0.5 times in southern South China, southern Zhejiang and southern Jiangsu.
