What month does it usually take to return to Nantian from Guangdong?

In what month does Hui Nan Tian in Guangdong usually end?

Hui Nan Tian in Guangdong usually occurs from February to March.

The main reason for the return to the south is that after the cold air moves away, the warm and humid air quickly counterattacks, causing the temperature to rise and the air humidity to increase. When the surface of some cold objects encounters the warm and humid air, it is easy to produce water droplets. . The phenomenon of returning to the south is more serious in the south, which is related to the fact that the south is close to the sea and the air is humid. When "Hui Nan Tian" appears, the air humidity is close to saturation, and water will appear on the walls and even the ground. There is a wet scene everywhere, and water seems to be squeezed out of the air. The dense fog is the most distinctive appearance of "Returning to the South Sky".

According to statistics, when the phenomenon of returning to the south is severe, the visibility can be reduced to 50 meters. In the weather back in the south, some items or food are easily affected by moisture and may become moldy and rotten. Therefore, appropriate moisture-proof measures must be taken.

From a meteorological point of view, after a long period of low temperature, the surface and inside of the object are completely cold, and when the temperature of the object is less than or equal to the dew point temperature, the water vapor in the air reaches saturation. , it begins to condense on the surface of the object, forming water droplets, and the phenomenon of returning to the south arises. The so-called dew point temperature refers to the temperature when the air temperature drops to the point where the air reaches saturation under the condition that the water vapor content and air pressure in the air remain unchanged. The main reason is that after the cold air passes, the warm and moist airflow quickly counterattacks, causing the temperature to rise and the air humidity to increase. When the surface of some cold objects encounters the warm and moist airflow, it is easy to produce water droplets.

Things to note when traveling back to Nantian:

Wipers

Wipers can play a big role in the humid "Hui Nantian". When "Hui Nan Tian" is driving on the road, water mist is easily attached to the outside of the window glass, thus affecting the driving vision. At this time, we should turn on the wipers to sweep away the water mist on the windshield. Therefore, when the "return to the south" is approaching, car owners should remember to check the wipers frequently to see if they can work normally and whether the wiper strips can be wiped clean. If any problems are found, they should be solved as soon as possible.

Fog lights

In the foggy weather of "Back to the South", the role of fog lights is also very important. Because fog lights have strong penetrating power, they can ensure that vehicles are more easily noticed by other vehicles in foggy weather, thereby avoiding traffic accidents. Therefore, it is particularly important to ensure the normal operation of fog lights in "back to the south" or foggy weather.

Vehicle Electronic Systems

Moisture is a natural nemesis for electronic devices. When the humidity in "Hui Nan Tian" is severe, when we turn on the TV, we will find that the screen has become blurry due to moisture. Similar to televisions, this situation may also occur in vehicle electronic systems - if they are severely affected by moisture, they may not be able to display or play properly after being turned on, or even cause a short circuit in the circuit.

Battery

When "returning to Nantian", some vehicles will have trouble starting. At this time, the owner should pay attention to check whether the battery is in normal condition. If the battery is more than two years old, the battery may self-discharge in humid weather and may consume too much power, making it difficult to start the car.

Pay attention to whether there is water in the spare tire tank

Since the spare tire tank is not a sealed design, it is easy to get damp or even water in the event of a "return to the south" or constant rain. . During wet weather, it is necessary for car owners to check the spare tire well to avoid getting wet.
