Moisture mucus phenomenon and causes
Moist weather is a phenomenon that occurs when the humidity is higher than 90%. This phenomenon mostly only occurs in houses close to the ground and low-rise. The upper floors of buildings like apartments will have less humidity. The higher it gets, the lower the humidity.
The phenomenon of moisture in the North occurs due to prolonged cold and dry air causing the humidity of walls, floors, and furniture to drop. Next, the monsoon in the North will bring a humid air blowing from the sea to the mainland at higher temperatures. When the low temperature of walls, floors, and objects are exposed to the high air temperature of the environment, the phenomenon of fog occurs.
Similar to placing a glass of ice in the air, the glass wall is often flooded with minute-ly water. This physical phenomenon occurs because the temperature of the glass wall is lower than the temperature of the environment, causing the water vents in the air to clump up into droplets.
How long does a humid footrest last?
According to information from the Weather Forecast Department (National Center for Hydro-Meteorological Forecasting), every year, the phenomenon of stormy weather usually occurs at the end of spring, from February to the end of April in Hanoi and the northern provinces. The long or short flight time depends largely on the Northeast monsoon that moves into our country.
Usually, each bidding period will last 3-5 days or a whole week. Depending on the temperature difference between the surface of the object and the air mass, the humidity will be different. In March, there are usually about 4-5 sagging waves, with different shortened and long periods.
