For more details about the 2018 lunar calendar for March, please visit the Fortune Teller website for consultation!Will it rain during the Grain Rain solar term in 2018?There is a high chance of rain.Weather characteristics of Guyu: "Rain brings forth all kinds of grains"The ancients made the judgment that "rain brings forth all kinds of grains" based on thousands of years of experience in climate. According to the weather characteristics of previous Grain Rains, the amount of rainfall during the Grain Rain solar term increases, so it is likely to rain during the Grain Rain.Generally speaking, during the Grain Rain solar term, the high-altitude westerly jet stream in East Asia will once again significantly weaken 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." At this time, most of the eastern part of southern my country has abundant rainfall, with annual rainfall in late April being about 30 to 50 mm. The first heavy rain of each year usually occurs during this period, which is beneficial to rice planting and the growth of corn and cotton seedlings. However, the rest of South China received less than 30 mm of rainfall, so irrigation measures are needed to mitigate the effects of drought. The northwestern plateau and mountainous areas are still in the dry season, with precipitation generally only 5 to 20 mm. The rainfall before and after Grain Rain in South China often "sneaks into the night with the wind, moistening everything silently". This is because "Night Rain in Bashan" is most likely to occur in April and May. "It often rains at night in Shu, but the river bank is clear in the morning." This kind of weather with rain at night and clear days is quite suitable for the growth of major spring crops and the harvest of minor spring crops. However, it should also be noted that it does not necessarily rain during Grain Rain. Grain Rain just means that there is a higher probability of rain. Whether it will rain in each area every day should be judged based on the actual situation. We should know that weather forecasts may also have false alarms, not to mention an agricultural proverb from thousands of years ago. According to meteorological records, the probability of rain on the day of "Guyu" in a certain area is 58%, that is, there is rain on Guyu in 35 years out of 60 years, and 46% of them have higher annual precipitation; in the 25 years without rain on Guyu, 48% of them meet the phenomenon of "no rain on Guyu and lower annual precipitation". Therefore, some meteorological experts believe that whether it rains during the Guyu period cannot accurately predict the amount of rainfall in the later part of the year. What is the difference between Guyu and Rainwater?Grain Rain is one of the 24 solar terms. 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.Rainwater - indicates that precipitation has begun and the amount of rainfall is gradually increasing. 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. 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. The name Guyu, at first glance, indicates that it 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." After the beginning of spring, the climate is always changing, sometimes warm and sometimes cold, with a wind every three days and a cold wave every five days. During the Grain Rain Festival, the temperature across the country rose rapidly and then stabilized. As the temperature rises. There was also plenty of rain, and various crops had good growing conditions and became increasingly thriving. South of the Yangtze River, there is more rain and rainbows have appeared. The early rice seedlings have grown two or three leaves, the rapeseed is blooming and forming pods, and bees and butterflies are flying.
