Introduction: Dahan is one of the 24 solar terms, and it is also an important solar term. So is Dahan the coldest time of the year? Analysis of the climate characteristics of Dahan! The twelfth month of the lunar calendar is the twelfth month, commonly known as the end of the year, and is also known as Ladong, Candong, Qiongdong, Layue, and Bingyue. Let’s go to Shuimoxiansheng.com to check out the relevant content for the twelfth month of the lunar calendar in 2018.Is the Great Cold the coldest time of the year?The Great Cold is theoretically the coldest time, but the actual situation may not be that.In fact, the winter solstice is the day with the shortest day and the longest night in the year. From the winter solstice, we enter the coldest days of winter, which means that every day thereafter may create the lowest temperature of the winter. During the winter solstice, the earth's surface receives the least sunlight and heat, but there is still heat supplement from deep in the soil, so it is not yet the coldest time of the year. After the "Winter Solstice", the heat deep in the soil is gradually depleted. Although the amount of sunlight and heat increases slightly, it is still not enough to cover the expenditure. Therefore, the lowest temperature of the year is most likely to occur during this period. Data from the Meteorological Bureau show that from statistics on the national average temperatures during the Lesser Cold and Greater Cold seasons from 1951 to 2015, it was found that in 42% of the years the Lesser Cold was colder than the Greater Cold, in 28% of the years the Greater Cold was colder than the Lesser Cold, and the remaining 30% of the years were the same, with a similar degree of coldness. Analysis of the characteristics of the severe cold climate!Widespread rain and snow, strong winds and cooling <br /> During the Great Cold period, the atmospheric circulation is relatively stable, and the circulation adjustment cycle is about 20 days. When this circulation adjusts, large-scale rain, snow, strong winds and cooling temperatures often occur. When there is a long wave ridge west of 80 degrees east longitude and a large coastal trough in East Asia, my country will experience sustained low temperatures due to the control of northwesterly airflow and the continuous replenishment of cold air. In some parts of my country, the Great Cold is not as cold as the Lesser Cold. However, in some years and a few coastal areas, the lowest temperature of the year still occurs during the Great Cold. Therefore, we should continue to protect crops from the cold, and special attention should be paid to protecting livestock from the cold.The least rainfall in the year <br /> During the Great Cold, the average temperature in most parts of southern China is 6℃ to 8℃, which is nearly 1℃ higher than the Lesser Cold. The proverb "Lesser Cold and Greater Cold, it's extremely cold" indicates that the Greater Cold is also a cold period of the year. Lesser Cold and Greater Cold are the periods with the least rainfall in a year. During the Great Cold season every year, rainfall in most parts of southern China increases only slightly compared with the previous period, 5 to 10 mm in most parts of south China, and only 1 to 5 mm in the northwestern plateau and mountainous areas. Frequent cold waves <br /> During the Great Cold period, cold waves frequently move southward, making it a relatively cold period of the year in most parts of China. Railway, post and telecommunications, petroleum, and maritime transport departments should pay special attention to taking early measures to prevent disastrous weather such as strong winds, cooling temperatures, and heavy snow. In agriculture, we must strengthen the protection of livestock and overwintering crops against cold and frost.
