Grain Rain refers to the increase in rainfall, which is greatly beneficial to the growth of cereal crops. Grain Rain occurs on April 20 or 21 every year when the sun reaches 30° of the ecliptic longitude. The temperature is relatively high during Grain Rain, and it rains frequently. After the Grain Rain, the rainfall increases and the rainfall is sufficient and timely.2. Rainwater indicates the beginning of precipitation and the amount of rainfall gradually increases. The weather during the Rain Water solar term is unpredictable and is one of the seasons with the most cold waves throughout the year, with sudden changes from hot to cold. 3. The Rain Water solar term falls around February 18th of the Gregorian calendar every year. At this time, the sun reaches 330 degrees of ecliptic longitude, marking the beginning of the "Rain Water" solar term. Rainwater has two meanings. One is that the weather is warming up and the precipitation is gradually increasing. The other is that in the form of precipitation, there is less snow and more rain. 4. The name Guyu refers to the climate conditions. But it is different from the Rain Water Festival. Yu Shui means "spring rain is coming"; while Gu Yu connects rain and grain together. According to the ancients' explanation, it means "rain gives birth to hundreds of grains." The Origin of GuyuGuyu means "rain brings forth all kinds of grains" and it occurs when the sun reaches 30° of the ecliptic longitude on April 20 or 21 every year.During the Grain Rain season, in southern China, "the poplar flowers have all fallen, the cuckoos are crying", willow catkins are flying, the cuckoos are crying at night, the peonies are blooming, and the cherries are ripe. The natural scenery tells people that it is late spring. At this time, the temperature in the south rises rapidly. Generally, the average temperature in late April, except for northern South China and some western areas, has reached 20℃ to 22℃, which is more than 2℃ higher than mid-month. In the eastern part of South China, the temperature often rises above 30 degrees for one or two days, making people begin to feel the heat. The low-altitude river valley areas have also entered summer. In ancient China, Grain Rain was divided into three stages: "The first stage is when duckweed begins to grow; the second stage is when cuckoos flap their feathers; the third stage is when hoopoes descend on mulberry trees." This means that after Grain Rain, rainfall increases, duckweed begins to grow, then cuckoos begin to remind people to sow seeds, and finally hoopoes begin to be seen on mulberry trees. During the Grain Rain solar term, the high-altitude westerly jet stream in East Asia will once again weaken significantly and move northward. The warm and humid air mass in South China will be relatively active, the westerly belt will circulate frequently from west to east, and the low pressure and Jianghuai cyclone activities will gradually increase. Under its influence, there will be continuous rain or strong winds and rainstorms in the Jianghuai region. Grain Rain is the last solar term in spring. At this time, the seedlings in the fields are first planted and the crops are newly planted, which need rain the most. That is why it is said that "spring rain is as precious as oil." |
