Is there cold air in Shandong?

Shandong has really felt the obvious cold weather these days. The influence of this cold air is mainly related to the change of atmospheric circulation. Cold air moving from north to south will affect Shandong. At the same time, the influence of topography on climate is also an important factor.

First of all, since the winter of this year, especially recently, the temperature has been significantly lower than that of the same period last year, and this cold situation will continue for some time. The weather forecast also predicts that the temperature will continue to drop, and it may even drop to a few degrees below zero at night. In such weather conditions, everyone needs to keep warm and try to avoid outdoor activities.

In addition, the cloud cover in the sky has increased recently, and the precipitation has also increased. It is difficult for the water on the surface and in the air to evaporate quickly, further reducing the temperature. In this environment, the human body feels colder, so you will find that even indoors, it will feel cold.

In terms of clothing preparation, it is recommended to wear some warm clothes, such as down jackets and sweaters. Shoes also need to choose good thermal performance, such as wool boots. Indoor, you can consider using heating equipment to raise the room temperature, but you must pay attention to safety and avoid fire hazards.

The cause of cold weather

Latitude factor: the latitude of the earth has a great influence on temperature. In high latitudes, the temperature is relatively low because of less solar radiation. With the increase of latitude, the intensity of solar radiation gradually weakens, resulting in a drop in temperature. Therefore, in winter, high latitudes are usually colder than low latitudes.

2. Atmospheric circulation: Atmospheric circulation is an important factor affecting temperature. In winter, Siberian high often controls the northern part of the Asian continent, causing cold air to go south and bring cold weather. This high-pressure system will lead to lower temperature, stronger wind and less precipitation. Therefore, atmospheric circulation is one of the important reasons for the cold weather.

3. Land and sea distribution: The sea and land also have great influence on the temperature. The ocean usually has a high specific heat capacity, which means that the ocean responds slowly to temperature changes. In contrast, the specific heat capacity of land is low and it responds quickly to temperature changes. Therefore, in winter, the land surface temperature drops rapidly, while the ocean surface temperature drops slowly. This difference makes it easier for cold air to accumulate on land, thus forming colder weather.
