However, not everyone gets what they want. Regarding summer, many people have heard of the dog days. So what are the dog days of summer? What are the climatic characteristics of the dog days of summer? Let’s follow the editor to learn more about it. Mr. Shui Mo has carefully compiled a special topic about the sixth month of the lunar calendar. Friends who want to know more about the sixth month of the lunar calendar can read the relevant articles in this topic for reference!Definition of Dog DaysA collective name for the first, middle and last dog days. The first and last dog days of each year last 10 days each, while the middle dog days lasts from 10 to 20 days. The specific dates of the Three Fu are determined by the combination of the dates of the solar terms and the dates of the Ganzhi calendar. Geng is the seventh among the Heavenly Stems and belongs to gold in the Five Elements. Gold is afraid of fire and its energy will gradually decrease during the dog days. Therefore, the ancients used Geng days to count the "dog days". According to my country's traditional calculation method, the third Geng day and the fourth Geng day after the summer solstice are the starting dates of the first and middle Fu periods respectively, and the first Geng day after the beginning of autumn is the first day of the last Fu period. The length of the dog days is not exactly the same every year. If the middle dog days ends after the Beginning of Autumn, it is 30 days; if it ends before the Beginning of Autumn, it is 40 days (20 days in the middle dog days).Climate characteristics of dog daysIt is the hottest time of the year with high temperature, low air pressure, high humidity and low wind speed. This is because the days in summer are longer than the nights, and the daytime hours are long, and the sunshine time is also long. The heat absorbed by the surface is much greater than the expenditure, which makes the heat accumulated in the ground increase day by day, and the temperature continues to rise. In midsummer, that is, during the dog days of summer, the accumulation of surface heat reaches its peak. There is a lot of rain in summer and the air humidity is high. The heat capacity of water is much greater than that of dry air. This is also one of the important reasons for the hot and humid weather.The ancients lived in a harsh environment without air conditioning or electric fans. Imagine if they studied literature and martial arts under such difficult conditions, wouldn’t it be a great test of their willpower? No wonder they say “train hard during the hottest days of summer”. Summary: Through the above article, we have a certain understanding of the definition and climate characteristics of the dog days. I hope that everyone can have a deep understanding of the dog days! |
