Climatic characteristics of summer solstice 24 solar terms.

Introduction: It's summer, which means it's hot. In this season of rising temperature, we should prevent the troubles caused by high temperature, and also be careful not to be bored, otherwise it is easy to get angry. So, what are the climatic characteristics of summer solstice? What are the climatic characteristics of the 24 solar terms during the summer solstice? If you want to know, please take a look at my introduction.

Climatic characteristics of summer solstice

1. Climatic characteristics of solar terms from summer solstice: rainy season.

Summer solstice season is the "Meiyu" season in Jianghuai area. At this time, it is the ripe 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.

2. Climatic characteristics of solar terms from summer to solar terms: convective weather.

After the summer solstice, the ground is heated strongly and the air convection is strong, and thunderstorms are often easy to form in the afternoon to evening. This kind of hot thunderstorm comes and goes, and the rainfall range is small. People call it "dividing fields in summer and rain". Liu Yuxi, a poet in the Tang Dynasty, skillfully used this weather to write a famous poem, "The east rises and the west falls, and the road is sunny and sunny." The heavy precipitation brought by convective weather is not always as beautiful as described in the poem, and it often brings local disasters.

Climatic characteristics of summer solstice solar terms: high temperature sauna

Like the winter solstice, the summer solstice is also a solar term reflecting the changes of the four seasons. Astronomy stipulates that the summer solstice is the beginning of summer in the northern hemisphere. After the summer solstice, although the direct point of the sun began to move southward from the Tropic of Cancer, the days in the northern hemisphere became shorter and the nights became longer. For the Tropic of Cancer and its northern area, the height of the sun is also decreasing day by day. However, because the heat radiated by the sun to the ground is still more than that radiated from the ground to the air, the temperature will continue to rise in the future, so there is a saying that the summer solstice is not too hot. According to the data of 195 1 to 2006, the historical extremes of many cities in the north appeared after the summer solstice.

Climatic characteristics of summer solstice solar terms: rainstorm weather.

In most cases, during the "summer solstice" period, 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 work. 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.

Climatic characteristics of summer solstice in 24 solar terms

The summer solstice, also known as the summer season and the summer solstice festival, is the tenth solar term among the 24 solar terms and the middle of May among the 24 solar terms. From the name, the arrival of summer solstice represents the arrival of hot summer.

The summer solstice is the northernmost day of the year, and it is also the longest sunshine day in the northern hemisphere. However, after the summer solstice, the direct point of the sun is gradually difficult to move away from the tropic of cancer, and the days in the northern hemisphere begin to shorten.

Summer solstice is characterized by heavy rain, rainy weather, high temperature and high humidity. In other words, after the summer solstice, the ground is heated strongly, which is easy to form convective weather. For example, thunderstorms with a relatively small rainfall range are prone to occur.

In addition, there will be "Meiyu" weather in Jianghuai area of China. At this time, the air is very humid, and the cold and warm air masses meet here to form a trough of low pressure, and rainy weather will occur.

At this time, the moisture in the air increases and becomes more humid. At this time, we should pay attention to moisture-proof hygiene, and high temperature and humidity are easy to breed bacteria.

In addition, with the arrival of the summer solstice, the most obvious weather change is that the temperature will continue to rise for some time. For the summer solstice, there is a folk saying that the summer solstice is not too hot.

When is the hottest in summer?

July and August are the hottest months, and "three volts" refers to the first, middle and last three volts, which is about from mid-July to mid-August every year. After the summer solstice, although the days are getting shorter and the nights are getting longer, the days are longer than the nights in a day. Every day, the ground absorbs more heat than it emits, and the temperature near the ground is getting higher every day. During the "three volts" period, the heat absorbed by the ground is almost less than the heat emitted, and the weather is the hottest.

After that, the heat absorbed by the ground began to be less than the heat emitted by the ground, and the temperature gradually decreased. Therefore, the hottest time of the year generally appears in the "dog days" from the summer solstice.

The hottest day in summer is 2-3 pm. At this time, although the sun sets in the west, the altitude angle is still very large, and the heat stored on the surface is still greater than the heat released, which makes the temperature continue to rise, the local surface heat balance, and the surface temperature reaches its peak. After that, the surface releases more heat than it stores, which makes the surface temperature lower.
