What are the characteristics of the summer climate from solstice to solstice?
In most parts of China, the summer solstice season is plum rain in the middle and lower reaches of the Yangtze River and the Jianghuai Valley, with frequent rainstorms, which are easy to cause floods and even threaten people's lives and property. Therefore, attention should be paid to strengthening flood control. After the summer solstice, relevant departments should pay attention to the adverse effects of rain on transportation and tourism, and do corresponding preventive work; Please walk slowly and carefully on the way to work, and pay attention to the road conditions and weather changes in time.
(1) Convective weather: After the summer solstice, the ground is strongly heated and the air convection is strong, and thunderstorms often form in the afternoon to evening. This kind of hot thunderstorm comes and goes, and the rainfall range is small. People call it summer rain over the mountains. Liu Yuxi, a poet in the Tang Dynasty, skillfully used this weather to write a famous poem: Rising in the East and Falling in the West, the Tao is sunny or sunny. The heavy precipitation brought by convective weather is not always as beautiful as described in the poem, and it often brings local disasters.
(2) Rainstorm weather: During the summer solstice, most parts of China have high temperature, abundant sunshine, rapid growth of crops and more physiological and ecological water demand. At this time, precipitation has a great influence on agricultural output. There is a saying that raindrops from summer solstice are worth thousands of dollars. At this time, the precipitation in the middle and lower reaches of the Yangtze River can generally meet the needs of crop growth. In most cases, during the summer solstice, the middle and lower reaches of the Yangtze River and the Jianghuai basin are rainy and frequently rainstorm, which is easy to cause floods and even threaten people's lives and property. Attention should be paid to strengthening flood control.
(3) Meiyu in Jianghuai: Summer solstice is the rainy season in Jianghuai area. At this time, it is the yellow ripening period of plums in Jiangnan, and the air is very humid. Cold and warm air masses meet here, forming a trough of low pressure, leading to rainy weather. In this weather, the utensils are moldy and the human body feels uncomfortable. Some mosquitoes breed quickly, and some intestinal bacteria are easy to breed. At this time, we should pay attention to drinking water hygiene and try not to eat cold food to prevent the occurrence and spread of infectious diseases.
(4) High temperature sauna. The summer solstice means that the hot weather officially begins and then gets hotter and hotter, so there is a folk saying that the summer solstice is not too hot. From summer to the future, although the direct point of the sun gradually moves southward, the days in most parts of the northern hemisphere are shorter and the nights are longer, but the heat radiated by the sun to the ground is still more than the heat radiated from the ground to the air, so the temperature will continue to rise in the future.
