The Central Meteorological Observatory issued the first high temperature red warning in history. Why did this happen? What are the impacts?
It is understood that the Central Meteorological Observatory officially issued the first high temperature red warning on the afternoon of August 12. You must know that the high temperature red warning is the highest level weather warning. Under such hot conditions in 2013 and 2017, the high temperature warning issued by the Central Meteorological Observatory was only an orange warning. The red warning issued this time is already above the orange warning. The reason why the Central Meteorological Observatory issued a high-temperature red warning is mainly because the temperature this summer has exceeded the historical value for the same period. Not only is the temperature the highest and strongest, but it is also extremely long-lasting and wide-ranging. It has caused serious consequences to all aspects of people's daily lives. some impact.
Usually, my country's high temperature warning is divided into three levels, from low to high, which are yellow, orange and red. Among them, the high temperature red warning is the highest level. The Central Meteorological Observatory issued the first high-temperature red warning, which means that the scope and intensity of high-temperature weather in our country have reached a relatively large extent. The temperature in many areas has reached above 40°C. It is expected that this rare event will follow. The hot weather will continue.
Persistent high temperature weather not only affects people's lives, but also has a huge blow to agriculture. If people stay in a high temperature environment for a long time, they will often feel irritable and stuffy, their body temperature will also rise, and they will not like to engage in various outdoor activities. Especially for some elderly people, high temperature weather will have a greater impact on the body, because the body temperature regulation function of the elderly is relatively poor, so high temperature weather is likely to cause various diseases in the elderly. .
Generally speaking, high temperature weather in normal climate will not have an impact on agriculture, but if abnormal high temperatures occur, it will undoubtedly bring a huge blow to agriculture. Because the temperature is too high and there is little rain, the moisture 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 and reduce profits for farmers. The final impact will naturally be on the price of crops.
