what principle of South moisture in China

What's the principle of South moisture in China? From the perspective of meteorology, when after a long period of time at low temperature, objects excluded from the cold, the temperature of the object is less than or equal to the dew point temperature, water vapor in the air reaches saturation, began to condense, in the object surface water back to the south of the resulting phenomenon.

The so-called dew point temperature refers to the temperature in the air under the condition of water vapor content and air pressure constant, when the temperature drops to the saturation of the air. Mainly because the cold air after the warm moisture flow back quickly, resulting in temperature recovery, air humidity increased, and some cold objects surface encountered warm and humid air, it is easy to produce water droplets.

Back in the spring, the walls and floors of the south end will come out of the water. In fact, they are similar to the principle of sea fog.

Warm and humid ocean currents flow from warmer sea to cool sea surface. The water vapor in the air freezes and condenses into fog droplets, which accumulate in the air and form fog. If the air flow through the sea surface temperature difference is large, the fog is also a greater opportunity.

Similarly, the walls and floors were cooled by cold weather in winter. If warm and humid air flows through walls and floors, the water in the air freezes and condenses into droplets, attached to walls and floors, as if walls and floors ooze water.

In the summer, even though there is a damp ocean wind, but the walls and floors are not cold enough, the walls and floors do not come out of the water.
