The omen before the typhoon comes.

Signs before the typhoon: the temperature rises gradually, the humidity increases gradually, the weather turns cloudy, and the air is filled with the smell of sea water.

1, the temperature gradually rises: when a typhoon comes, the weather will gradually become humid and the temperature will gradually rise, which is usually the most obvious a few days before the typhoon comes.

2. Humidity gradually increases: Before the arrival of the typhoon, the humidity will gradually increase, and the moisture content in the atmosphere will also gradually increase, which is one of the reasons why we feel difficult to breathe.

3. The weather turns cloudy: When the typhoon comes, the originally sunny weather will gradually become gloomy, and dark clouds will cover us like a big pressure.

4. The air is filled with the smell of seawater: When the typhoon comes, the air will also be filled with the smell of seawater, because the strong airflow brought by the typhoon can carry the salt in seawater into the air and disperse it.
