Weather: Why is the weather in Guangzhou so humid and uncomfortable?

Don't worry, this is an anti-tide, also known as "returning to the south sky", which usually appears in February and March in spring. The main reason is that after the cold air leaves, 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. 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. In the morning and evening, when the damp "going back to the south" strikes, everyone must remember to close the windows at home, especially the windows facing south and southeast, so as not to give the moisture eyeing outside the window any chance to sneak in. The most important period of moistureproof is in the morning and evening of every day. The air humidity in these two periods is higher than that at noon. If you don't close the doors and windows in time, and feel that the indoor air can't circulate because of the closed doors and windows, I suggest you open the window for ventilation for a short time at noon. How to prevent "going back to the south"? Pay more attention to the weather forecast and see what the humidity is every day. If the humidity is high and the temperature is only 10 degrees, then open the window less at home. When the temperature is low, open more windows, and the moisture regain will be very severe. Mop the floor less when the weather is warm. Mop the floor when it is wet again, it will be wetter, and it will not be dry for a long time. It's no use blowing with a fan unless you use air conditioning. If the house is really dirty, you can wring out the mop so that it won't be too wet. You'd better put it off at noon and open the window, which will dry faster. Put a dry mat in front of the kitchen or bathroom to prevent more water from being brought into the living room and bedroom. If necessary, you can prepare a pair of slippers and change them into dry ones when they are wet. Health reminder: beware of respiratory diseases. Wet and foggy weather can easily lead to rheumatism recurrence, joint pain and muscle pain, so people with these diseases need to keep warm. Patients with chronic diseases such as hypertension should take medicine on time, monitor blood pressure, and pay attention to preventing the occurrence of diseases such as stroke. In addition, the "late spring cold" weather is easy to cause diseases such as upper respiratory tract infection and tonsillitis, while the humid weather is also a season with frequent skin diseases such as eczema, chapped skin, dermatitis and beriberi. The public should pay attention to prevention. Travel reminder: driving in rain and fog should slow down. In wet weather, we should pay special attention to the visibility of driving, check the safety and technical conditions of vehicles, especially the braking system, dry the rearview mirror, headlights and taillights, turn on fog lights, low beam lights, width lights and taillights as required, remind the rear vehicles, clean the front windshield of vehicles with wipers in time, and reduce the speed appropriately. Avoid using high beam in foggy days, lest the light be reflected into a blank by the fog in front of the car, and the car in front can't be seen clearly. Nothing, it will be fine in a few days!
