Where are the walls most susceptible to moisture in the south?

Back to the south of the sky, the wall with no sunshine in the shade is the most vulnerable to moisture.

Returning to Nantian is a phenomenon of warmer weather, which generally 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 "Returning to the South Sky" appeared, the air humidity was close to saturation, and the walls and even the ground would "boil water". 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"

In wet weather, we should pay special attention to the visibility of driving and check the technical status of vehicle safety.

Especially for the brake 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 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.
