What are the characteristics of the climate during the rainy season?

During the rainy season, the direct point of the sun is approached from the southern hemisphere towards the equator. At this time, the general trend of the national climate is the transition from cold in late winter to warm in early spring. The time of snowfall has passed in most parts of the country, the rain has begun, and the temperature has risen, but the rain is still mainly drizzle.

After the rain arrived, the temperature in most parts of China rose to above 0 degrees Celsius, and the average daily temperature in the Huanghuai Plain reached about 3 degrees Celsius, and the Jiangnan was about 5 degrees Celsius. However, at this time, the atmospheric circulation is in the adjustment stage, and it is also one of the periods when the cold wave occurs the most throughout the year.

In addition to rain, there are also many solar terms that reflect the characteristics of the climate. For example, valley rain, light snow, and heavy snow also reflect precipitation or snowfall. White dew, cold dew, and frost reflect the phenomenon of water vapor condensation and condensation.

The so-called spring rains are as expensive as oil, which refers to the importance of spring rains to agricultural production. Chen Xin introduced that the wintering crops in the winter seedlings are small, slow growth, water demand is not large, and the general winter drought has little impact on normal growth. However, before and after the rain season, the growth of crops is gradually vigorous, and the water demand gradually increases.

Winter wheat, for example, has a significantly higher demand for water when it grows back to green, so spring rain is as precious as oil. There are similar proverbs: "When the rain rains, the crops are good, the big spring and the small spring are a treasure", "Storing water is like hoarding grain, and the water is enough to fill the warehouse".

"Rain" is the second of the 24 solar terms, the ice and snow melt and scatter into rain, marking the beginning of precipitation, so it is called rain. With the arrival of the rainy season, in addition to the northeast and northwest are still cold, the temperature in many places in China has begun to rise. After the "rains", most of our country rose back above 0, and spring really came.

Rain, like light snow and heavy snow, is a solar term that reflects the phenomenon of precipitation. It indicates the beginning of precipitation, with a gradual increase in rainfall. In fact, rain has two meanings, one is that the weather is warmer, and the precipitation is gradually increasing; Second, in the form of precipitation, there is less snow and more rain.

The rainy solar term signifies the beginning of spring in the meteorological sense. At this time, in the Northern Hemisphere, the number and intensity of sunshine gradually increase, and the temperature begins to rise. In most parts of the south, peach and plum buds begin to bloom, and cherry blossoms bloom.

Regions such as the northwest and northeast are still in the cold. But the general trend across the country is to shift from the cold of late winter to the warmth of early spring.

The characteristics of the rainy season: the temperature rises, the sunlight is warm, the warm and humid air is active, and the precipitation increases.

Rain is the second of the 24 solar terms. Rain, like the solar terms such as valley rain, small man, light snow, and heavy snow, is a solar term that reflects the phenomenon of precipitation, and is a reflection of the festivals in ancient farming culture. As the saying goes, "spring rain is as expensive as oil", and suitable precipitation is important for the growth of crops.

Entering the rainy season, South China is full of spring and flowers are in full bloom. If "Beginning of Spring" is the first movement of spring, "Sonata": spring germinates and spring is cold.

After the rain, it is time for the second movement of spring, "Variations": the temperature rises, the cold is warm, the warm and humid air is active, and the precipitation increases.

The rain solar term is mostly due to the fact that the direct sun point is gradually approaching the equator from the southern hemisphere at this time, and in the northern hemisphere at this time, the daylight hours are gradually increasing, the sunshine hours and intensity are increasing, the temperature rises rapidly, and the warm and humid air from the ocean begins to be active and advances northward. Before the cold air completely receded, the confluence of cold and warm airflows produced rainfall, so the rainfall in Yanling gradually increased.

The significance of the rain solar term:

With the arrival of the rainy season, the snowflakes are flying, the cold weather is gradually disappearing, and the spring breeze is blowing, the snow and ice are melting, and the moist air, mild sunshine and light drizzle days are coming to us.

Du Fu has a poem: "Good rain knows the season, when spring happens." Dive into the night with the wind, moisturizing things silently.

The poet vividly describes spring as the season when all things sprout and grow, and when the rain is needed, it comes, and this spring rain is accompanied by the wind, and when night falls, it quietly, silently, and delicately moistens all things.

The poet uses anthropomorphism to personify the rain, saying that it "knows the season" and knows how to meet objective needs. In the spring, when everything sprouts and grows, when the rain is needed, it starts to rain.

It is often said: "The beginning of spring is getting warmer, and the rain is busy sending fertilizer." "The plan of the year lies in the spring, and how to look at the rain in the spring. For farmers, rain is a critical period for the management of the spring and the preparation for the spring season, and our lives are full of new hope.
