Detailed Data Collection in Meiyu Season

The rainy season is a continuous stage of regional climate phenomenon. Because it is roughly equivalent to the ripening time of plums, it is named.

Chinese name: Nature of rainy season: duration of climate phenomenon: climate phenomenon: cloudy or rainy in June and July every year, distribution, causes, time, characteristics, related terms, life guides, and related poems. Meiyu, also known as Huangmeitian, refers to the middle and lower reaches of the Yangtze River in China, Taiwan Province Province, south-central Japan and South Korea. From the middle and late June to the first half of July every year. Because plum rains occur when plums are ripe in the south of the Yangtze River, China people call this climate phenomenon "plum rains" or "plum rains season". During the rainy season, the air humidity is high, the temperature is high, and clothes are easy to get moldy, so some people call the rainy season "moldy rain" with the same sound. Meiyu mainly occurs in the middle and lower reaches of the Yangtze River in China, Taiwan Province Province, the southern tip of the Korean Peninsula and south-central Japan in the subtropical monsoon climate zone, while there is no Meiyu in other parts of the world at the same latitude. Although there is no obvious phenomenon of plum rain in South China, the influence of plum rain is also great. Causes Every year from late May to early June, cold air from the north and warm air from the south meet in South China, forming a quasi-static front in South China. By the end of June, the influence of warm air was strengthened, and the quasi-static front moved northward to Jianghuai area, becoming the quasi-static front of Jianghuai (also known as Meiyu front). Because the warm air from the south carries a lot of water vapor, when it meets the cold air mass, it will produce a lot of convection activities. Because the cold and warm air forces are similar during this period, the front stays in the Jianghuai area. To put it simply, it is related to the subtropical high in the western Pacific: during the rainy season, the cold air in the north often goes south, and the warm and humid airflow in the southwest goes deep into the north, and the cold and warm air meet, generally forming a rain belt. In normal times, it will be fine if it rains, but it happened that the western Pacific subtropical high system moved northward and pushed this rain belt to the above areas. On the first day after planting, plum blossoms are the first before sunrise in Xia Hou. May always comes on June 6~ 15, and May always comes on July 8~ 19. There is an obvious rainy season in eastern China, with a long rainy season and relatively concentrated rainfall. Generally speaking, the higher the latitude, the later the meiyu begins. Taiwan Province Province entered Mei in mid-May and came out in mid-June. Japan entered Mei in late May and came out in late July. In the middle and lower reaches of the Yangtze River in China, plum blossoms enter in mid-June and come out in early July on average. But there are some differences in specific places. In Zhejiang, plum blossoms enter the plum blossom in May of the lunar calendar. Specifically, plum blossoms enter the plum blossom in the morning after the awning, and they rise on the solstice of summer. The most obvious feature of the rainy season is continuous rainfall, high temperature and high humidity. Related terms China's almanac records the beginning and the whole day of Meiyu: the first day is called "Plum Blossom" (or "Plum Blossom") and the last day is called "Plum Blossom" (or "Plum Blossom Break"). The range, duration and rainfall of Meiyu vary greatly every year. In some places where there should be plum rain, if there is no plum rain in some years, this phenomenon is called empty plum rain. After the rainy season in Huangmei, it usually clears up and enters the hot summer. If it turns rainy again at this time and lasts for a long time, it seems that it has returned to the plum season, which is called "heavy plum". There is a folk proverb that says, "Little Summer Thunder, plum blossoms bloom." Life guide Meiyu is sometimes called "mildew rain", because during Meiyu, the temperature and humidity are "two high" and things are easy to get moldy. So, what should we pay attention to in the rainy season? 1, do not eat overnight dishes. The rainy season is often characterized by high temperature, high humidity and low air pressure, which is suitable for mold growth and reproduction. Mycotoxin can cause acute poisoning, chronic poisoning, teratogenesis and carcinogenesis, so rainy season is also a high incidence period of bacterial food poisoning. In diet, we should pay attention to the separation of raw and cooked food to avoid cross-infection; At room temperature, food is generally stored for no more than 2 hours, and it is best not to eat fresh vegetables overnight or every other meal. Usually eat light and digestible foods, such as melon, loofah, bitter gourd and mung bean soup. 2, travel without washing the car into the rainy season, not only rain, heavy rain, lightning and other disastrous weather began to increase. When traveling, the visibility is low, the road surface is slippery, and vehicles are easy to slip, so drive carefully. Pay attention to the weather forecast in time before going out, and make preventive preparations in advance. For car owners, there is no need to spend money and time washing cars in recent days. 3, seize the opportunity to dry clothes at home. Since plum rain is also called "mildew rain", it is naturally stuffy and wet. Carpets, cotton-padded clothes, furniture, etc. May be attacked by moisture and mold. Furniture should remove surface moisture in time; During the interval of precipitation, put on sofas, carpets, quilts, etc. Dry in the sun. Such as hair dryer, electric iron, etc. Can be used to remove moisture. Don't forget the dehumidification function of the air conditioner. When the room temperature drops to about 22℃, the relative humidity can be reduced by about 50%. Keeping home appliances on standby at the right time can also get rid of moisture. The related poem "Plum Rain" (Du Fu), xipu Road, Nanjing, is ripe in April. Zhan Zhan arrived at the Yangtze River, and the drizzle came. Hair is sparse and easy to wet, and clouds are dense and difficult to open. Unexpectedly, Longxi, vortex shore home. "Plum Rain" (Liu Zongyuan) Shi Mei welcomes the rainy season, which is infinitely valuable in late spring. I am so worried that I can't sleep at night. Monkeys cry at night, and good dreams easily wake chickens. Rain and fog spread from a corner of the sea to the end of the Antarctic, and Jiang Tao flooded the ferry from the north with a bang. White clothes are dyed by plum rains in the south of the Yangtze River, but not by the dust in Beijing. "You Yue" (Zhao Shixiu) It rains at home in Huangmei season, and frogs are everywhere in the grass pond. It's past midnight, and the invited guests haven't come yet. I tapped the chess pieces bored and shook the wick of an oil lamp. Song: rainy season singer: Ningning &; Poet's Album: High School Musical (China Edition) Lyrics: Poet: I don't know why I look at the sky in a daze, as if I have lost something. I don't quite understand. The dust covered with memories is slowly blown away by the wind. I don't understand why there is always a faint sadness. When the raindrops fall and you turn away, I suddenly understand that there is a deep love in my heart. Ningning: I don't know why I looked at the sky in a daze, as if I had lost something. Memories I don't quite understand are like moonlight on the sea. I am young and frivolous. I don't understand why there is always a faint sadness. When the raindrops fall and you turn away, I suddenly understand that there is a love poet in my heart. Why are the days no longer wonderful? Why am I wandering alone in the rainy season? Because your thoughts have spread. Ningning: Why is the sky so cloudy? Why am I wandering alone in the rainy season? I want to have it. Poet: I'm a little mature, and I've learned to see how wonderful the past time will be tomorrow. After the rain, there will be blue sky. Ningning: I learned to be gentle and considerate. What a wonderful time in the past, there will be blue sky after rain and smog. You are a rainbow.
