The Central Meteorological Observatory issued the first high-temperature red warning in history. Why is this happening? What impact will it bring?

It is understood that the Central Meteorological Observatory officially issued the first high-temperature red warning on the afternoon of August 12. You should know that the high temperature red warning is the highest level of weather warning. Under the high temperature conditions of 20 13 and 20 17, the high temperature warning issued by the Central Meteorological Observatory is only an orange warning, and the red warning issued this time has been above the orange warning. The reason why the Central Meteorological Observatory issued the high-temperature red warning is because the temperature this summer has exceeded the historical value of the same period, which is not only the highest and strongest, but also has a particularly large duration and scope, which has had a certain impact on all aspects of people's daily life.

Under normal circumstances, China's high temperature warning is divided into three levels, from low to high, yellow, orange and red respectively, of which high temperature red warning is the highest level. The Central Meteorological Observatory issued the first high-temperature red warning, which means that the range and intensity of high-temperature weather in China have reached a relatively large level, and the temperature in many areas has reached above 40℃. It is expected that this rare high temperature weather will continue.

The continuous high temperature weather not only affects people's lives, but also brings a huge blow to agriculture. If people are in a high temperature environment for a long time, they will often feel irritable and sultry, and their body temperature will also rise, and they don't like to engage in various outdoor activities. Especially for some elderly people, high temperature weather will have a great impact on the body, because the body's temperature regulation function is relatively poor, so high temperature weather can easily lead to various diseases of the elderly.

Generally speaking, high temperature weather in normal climate will not affect agriculture, but if there is abnormal high temperature, it will undoubtedly bring a huge blow to agriculture. Because the temperature is too high and there is little rain, the water in the ground and soil will decrease. Once there is water shortage and drought, it will inevitably seriously affect the growth of crops. Farmers must irrigate crops, which will naturally increase costs, reduce farmers' profits and ultimately affect the prices of crops.
