Rainwater solar terms in recent years

As the second solar term in the twenty-four solar terms, rain usually occurs on the fifteenth day of the first month of each year (February 18-20. So when is the specific time of rainy season in recent years? Let's have a brief look at Bian Xiao's works.

Climatic characteristics of rain solar terms

The direct point of the rain solar term is that it gradually approaches the equator from the southern hemisphere. At this time, in the northern hemisphere, the sunshine hours and intensity are increasing, the temperature is rising rapidly, and the warm and humid air from the ocean is becoming active and gradually moving northward. At the same time, cold air is not to be outdone in the weakening trend, and it frequently competes with warm air, unwilling to quit its hegemony and refuse to take away the residual cold. At this time, the atmospheric circulation is in the adjustment stage, and the general trend of climate characteristics throughout the country is from cold in late winter to warm in early spring.

1. Middle and Lower Yellow River (North China)

At this time, the confrontation between cold and warm air did not bring about the sudden drop of temperature and the flying of snowflakes, but the arrival of spring breeze and spring rain. At this time, the average temperature in this area has risen above 0℃, and even the extreme maximum temperature during the day can reach above 20℃. There is no condition for snowfall, even if the ancestors were named after the first spring rain? Rain? , is also appropriate. In the rainy season, wheat has entered the stage of turning green, and at this time, wheat has higher requirements for water. At this time, it is the least rainy time of the year. From the surface climate data of China (197 1 ~ 2000), we calculated that the average rainfall in Shijiazhuang, Taiyuan and Beijing in February was only 7.4 mm, 5.2 mm and 4.9 mm respectively. Spring rain is as expensive as oil? .

2. Northwest and Northeast China

In the rainy season, the northwest and northeast of China are still not out of the category of winter. Judging from the average temperature in February, the monthly average temperatures in Lanzhou, Xining, Urumqi and Shenyang are-65438 0.0℃, -3.9℃, -9.7℃ and -6.9℃ respectively. It can be seen that these places have not got rid of the cold in winter, the weather is still dominated by cold, and the precipitation is dominated by snow.

In some places, the winter is still cold, and the weather is still mainly cold, and the precipitation is mainly snowfall.

3. Southwest and Jiangnan areas

During rainy days, except for the spring scenery in southern Yunnan, most places in the southwest and south of the Yangtze River are still a scene of early spring: the sun is warm, it is wet and cold in the morning and evening, the fields are green and the springs are warm. According to the division standard of four seasons: where is the average daily temperature for five consecutive days? 10℃-? At 22℃, spring begins. Generally speaking, the real "spring" in these places will come in late March, which is the "vernal equinox" season a month later. But there are also some special cases, such as Wuhan February 10, Changsha February 1 1, Nanchang February 1 1, and Nanjing February 2004 13. The time is fully advanced 1 month.

According to the multi-year average rainfall of 65438 10 and February, Wuhan is 43.4 mm and 58.7 mm, Changsha is 66. 1 mm and 95.2 mm, Nanchang is 74.0 mm and 100.7 mm, and Fujian is 48.0 mm and 86.6 mm, which shows the rainfall ratio of the above places in February.

4. South China

In the rainy season, South China is full of spring and flowers are in full bloom.

The annual average temperatures in the following cities in South China in February are: Guangzhou 14.5℃, Nanning 14. 1℃, Haikou 18.7℃. The average precipitation in the above cities in February was 69.4 mm, 42.6 mm and 35.0 mm respectively. Although the rainfall is several times more than that in the middle and lower reaches of the Yellow River, there is still water shortage due to high temperature and large evaporation. Especially in southern South China and parts of Hainan Island, the rainfall during this period is still relatively small, and spring droughts often occur. If the average temperature is lower than 10℃ under the influence of strong cold air, it is very unfavorable for early rice seedling raising.
