Does it mean that it will rain again tomorrow if cicadas shout loudly?

No. It just means it's hot. When the weather is hot, the male cicada will make a sound to attract the female cicada to mate. At the same time, with the change of air pressure, the cicada's cry will also change, becoming louder and more boring.

Five kinds of weather indicate that there may be heavy rain.

It's sultry in the morning, and even I find it difficult to breathe. There is often heavy rainfall in the afternoon. In the morning, I see the pagoda-shaped ink cloud uplift in the distance, and there will usually be strong thunderstorms in the afternoon; For several days in a row, the weather was clear and cloudless, especially hot. Suddenly, I saw a small cloud rising on the windward slope of the mountain, and there was usually a strong thunderstorm at midnight or early morning.

On a hot night, hearing the dull thunder not far away is usually a sign that a storm is coming; When you see funnel-shaped clouds or dragon's tail clouds on the horizon, it means that the weather is extremely unstable and there is the possibility of thunderstorms and strong winds at any time.

In case of heavy rain, quickly go to high places to avoid disaster.

Don't panic if you encounter heavy rain in the mountains. You must follow the instructions of experienced personnel and immediately look for high places to avoid disasters. If you encounter mountain torrents, don't stay in the valley, because the valley is the only way for mountain torrents.

At the same time, when encountering heavy rain, we should try to avoid crossing the river, prevent being washed away by sudden flash floods, and pay attention to preventing landslides, rolling stones and mudslides. A safe temporary shelter is an open and flat land far away from the disaster body. Do not stay on the hillside, concave slope or ravine with soft soil and unstable mountain nearby.
