When will Guangdong return to Nantian? When will Guangdong return to Nantian?

Guangdong huinantian usually appears in February-March.

The appearance of returning to the south sky is mainly due to the rapid counterattack of warm and humid airflow after the cold air leaves, which leads to the increase of temperature and air humidity. Some cold objects are easy to produce water droplets when they encounter warm and humid airflow. The tropic of Capricorn is more serious in the south, which is related to the sea and humid air in the south. When Return to the South Sky appeared, the air humidity was close to saturation, and the walls and even the ground would "bubble". Everywhere is wet, and the air seems to be able to wring water out. 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 serious, the visibility can be reduced to 50 meters. In the return weather in the south, some items or food are easy to get wet, and then moldy and rotten. Therefore, appropriate moisture-proof measures should be taken.

From the meteorological point of view, after a long period of low temperature, the surface of the object is completely cold. When the temperature of the object is less than or equal to the dew point temperature, the water vapor in the air reaches saturation and begins to condense on the surface of the object, producing water droplets and returning to the south. The so-called dew point temperature refers to the temperature when the air temperature drops to 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 humid airflow quickly counterattacks, resulting in an increase in temperature and air humidity. Some cold objects are easy to produce water droplets when they encounter warm and humid airflow.

Matters needing attention in traveling back to Nantian:

Windshield rain and snow brush

Wipers can play a great role in the wet "returning to the south sky" When "Back to Nantian" is driving on the road, water mist is easily attached to the outside of the window glass, which affects the driving vision. At this time, it is necessary to turn on the wiper to sweep away the water mist on the windshield. Therefore, on the occasion of "returning to the south", car owners and friends should remember to check the wiper frequently to see if it can work normally and whether the wiper strip can be scraped clean. When problems are found, they should be solved as soon as possible.

fog light

Fog lights also play an important role in the foggy days of "returning to the south". Due to the strong penetration of fog lights, vehicles can be more easily noticed by other vehicles in foggy days, thus avoiding traffic accidents. Therefore, it is particularly important to ensure the normal work of fog lights in "returning to the south" or foggy weather.

Vehicle electronic system

Moisture is the natural enemy of electronic equipment. When the humidity in Back to the South is serious, we turn on the TV and find that the screen has become blurred because of the humidity. Similar to the TV set, the vehicle electronic system may also have this situation-in the case of severe humidity, it may not display or play normally after being turned on, or even cause a short circuit.

storage battery

When "returning to Nantian", some vehicles will have difficulties in starting. At this point, the owner should pay attention to check whether the state of the battery is normal. If the service life of the battery has exceeded two years, in humid weather, the battery may self-discharge, which is easy to consume too much electricity, making it difficult to start the car.

Pay attention to whether there is water in the spare tire groove.

Because the spare tire groove is not sealed, it is easy to get wet or even accumulate water if you catch up with "going back to the south" or rainy weather. In wet weather, it is necessary for the owner to check the spare tire slot more to avoid getting wet.
