Why does Guangdong sometimes return to Nantian in winter?

As a southerner, I understand the pain of returning to Nantian too well. Back in the south, the sun outside is very hot and the moisture inside is very wet. Looking inside, the ceiling is sweating, the wardrobe door is sweating, the walls are sweating, and even the floor is sweating. It's no exaggeration, so many people will understand why southerners like bask in the quilt, because the room is too humid. Returning to Nantian usually occurs around March of the southern lunar calendar, or just after the rainy season, and occasionally the north returns to Nantian, but after all, the north is too dry. But what I want to talk about today is a special case. Even in winter, Guangdong occasionally returns to Nantian. Then why? Let's take a look.

Let's take a look at how Nantianhui was formed. Returning to the south is just a phenomenon of warmer weather. As we said, this kind usually appears after the rainy season in spring. The main reason is that the cold air in the air is gone, and the warm and humid air will soon occupy it, leading to an increase in temperature. However, the surface temperature of other objects in the room did not rise rapidly. Then when the humidity in the air gradually increases to a certain extent and touches the surface of these objects, it will liquefy and produce water droplets. This phenomenon mostly occurs in some coastal areas in the south.

Then why does Guangdong return to Nantian in winter? Mainly the geographical location of Guangdong and the phenomenon of warm winter. However, to talk about a weather phenomenon called El Nino event, the subtropical high over Guangdong is strong to the west, which makes the cold air not strong enough. At this time, the warm and humid air flow from the ocean is dominant. This warm current invaded Guangdong, and the land temperature was low, resulting in many liquefaction phenomena such as returning to the south or fog. Therefore, in 20 14 and 20 16, winter in Guangdong province also appeared.

What should I do when I return to Nantian? First of all, keep in mind the first point, that is, close the doors and windows, especially those facing due south or southeast. We should keep the humidity firmly out of the door and not give them a chance to invade, especially in the morning and evening when the humidity is the heaviest. Don't think the room is wet, open the window to ventilate, then you will regret it, because it will only get wetter and wetter. Dehumidifying products can be purchased in suitable supermarkets for dehumidification treatment.
