In the cold winter months, people often discuss the question: which is colder, the small cold or the big cold?
After many years of meteorological records, we can conclude that Xiaohan is the hottest day of the year, and only a few years when the temperature of Dahan will be lower than Xiaohan.
First of all, let's take a look at the two winter solar terms, Xiaohan and Dahan.
Xiaohan is the twenty-third of the 24 solar terms in the lunar calendar.
And the Great Han is the last of the 24 solar terms in the lunar calendar.
These two solar terms mark the arrival of winter and bring severe cold weather to people.
According to many years of meteorological records, Xiaohan is usually the coldest day of the year.
This is because in the cold season, the direct point of the sun in the northern hemisphere is close to the Tropic of Capricorn, the solar radiation energy is weak, and the water vapor in the atmosphere is also less, resulting in rapid heat dissipation on the ground and a sharp drop in temperature.
Therefore, the temperature during the small cold period is often very low, which brings great inconvenience to people's lives.
However, we can't ignore the effect of the cold on temperature.
While the Great Cold usually follows the Little Cold, in some years, the Great Cold may have lower temperatures than the Little Cold.
This is because climate change is a complex process that is influenced by a variety of factors.
For example, ocean temperature, atmospheric circulation, topography, etc., all have an impact on air temperature.
As a result, even during the Great Cold period after the Little Cold, the temperature may still be lower than the Little Cold in some years.
In addition to the change in temperature, the small cold and the big cold also brought other changes.
In the cold season, the earth begins to freeze, rivers and lakes freeze, and plants and trees wither, making it a cold scene.
In the cold season, the cold is even more severe, and the ice and snow cover the land, bringing greater challenges to people's lives.
In the face of such cold weather, people need to take a series of measures to protect themselves.
First of all, keep warm and wear thick clothing, especially on the areas of your head, hands and feet that are prone to cold.
Secondly, to keep the temperature in the room right, you can use heating equipment such as heating equipment or electric blankets to provide a warm environment.
In addition, it is also necessary to pay attention to eating a healthy diet and eat more warm foods, such as hot soups, hot drinks, etc., to increase the body's calories.
In addition to personal protection measures, society should also strengthen its response to cold weather.
* More investment in heating facilities can be made to ensure that people can live a warm winter.
At the same time, it can also strengthen the monitoring and early warning of cold weather, release weather information to the public in a timely manner, and remind people to prepare for the cold.
In short, Xiaohan and Dahan are both cold solar terms in winter, but according to many years of meteorological records, Xiaohan is usually the hottest day of the year, and only a few years when the temperature of Dahan will be lower than Xiaohan.
In the face of such severe cold weather, people need to take a series of measures to protect themselves and society, and also need to strengthen the response to cold weather.
Only in this way will we be able to have a warm, safe winter. Xiao Han
