How does the return of southern weather occur? And what to do about it? Find out at a glance!

In spring, southerners are sure to experience a return to the south. Just in the past two days, this year's return to southern China has suddenly arrived. As a Cantonese native, I know the power of a return to the south. The tear marks on the walls, the ground on thin ice, the accelerated decay of food, the clothes that have not yet dried. These are the things that, as the biggest annoyance of the southerly days, fill everyone who lives in the south with boredom!

So how did Back to the Southern Sky come about? Let's understand the cause and prescribe the right remedy. In more technical terms, the south of the subtropical monsoon climate forms a quasi-stationary front in March and April each year as cold air from south of Siberia meets warm, humid air from the South China Sea. The hot, humid air meets the cooler air and collects into small droplets. The air is saturated with water vapour at its maximum and therefore adheres to the surfaces of various objects.

Simply put, there is too much water vapour in the air. Because of the low temperature, it condenses into water droplets and adheres to the surface of objects. This is like when we take a hot shower in winter and the water vapour quickly makes the whole bathroom foggy with water droplets hanging from the mirror and tiles. The two key points are too much water vapour and low relative water vapour temperatures, which is why you don't go back south in the summer despite the humidity, because of the high summer temperatures.

Once you know the causes, you can prescribe the right remedy for them (of course, no matter what method you use, you can't completely solve the problem of going back south. After all, it is the whole environmental climate that is the problem, but it is still possible to avoid the effects of a southerly day indoors). We can start by controlling the temperature and humidity. However, it is difficult to control the temperature. Although we can regulate it with air conditioning, the rooms in the average home are not fitted with it and it is still costly to treat the symptoms rather than the root cause.

We can control the humidity. The first and least costly way is to close doors and windows, especially those facing south and southeast. Dehumidifying small spaces are relatively simple. If you want to ventilate for some time, it is best to choose midday. Humidity is lower at midday and highest in the morning and evening. Because the air is full of water vapour, then we isolate the humid air outside from entering the room, and then we dehumidify the room.

The air conditioner mentioned earlier is a good tool for dehumidification. The air conditioner has a dehumidification mode which works wonders for small spaces and dehumidifies quickly. You can turn it off when it has an effect to avoid excessive costs. You can also buy a dehumidifier if you have the means. The dehumidifier is relatively low-powered and we can leave it on all the time to achieve the dehumidifying effect. For clothes that cannot be dried, we can buy a dryer to dry them. After all, clothes are still difficult to dry.

All the above methods are very costly. We can also place some absorbent substances to absorb moisture. Such as soda, washing powder, activated charcoal, etc. or something like a dehumidifier box. But these things have very little application and are not very efficient in absorbing water. You should only use it in an emergency. Alternatively, you can light candles or aromatherapy to remove the musty smell and dry air.

Finally, we can't cope with the return of southern weather altogether. This widespread weather factor is difficult for humans to fully address. It also shows the insignificance of humans in the face of nature. Even if we can cope with it, there is nothing we can do to stop it. So for nature, we still need to be in awe and protect the environment!
