What are the signs that it is about to rain and what are the signs before it?

The signs before the rain are:

1.Drop in temperature: Rainy weather is usually accompanied by a drop in temperature, so if you feel that the temperature is significantly lower, you may want to consider whether it will rain.

2.Darkening of the sky: The sky can become darker and sometimes cloudy before the rain, so if the sky becomes gray or overcast, it could be a sign of rain.

3.Low pressure in clouds: Before rain, the air pressure is low, and the clouds are denser, and some low-pressure weather phenomena will occur, such as headache, fatigue, dry throat, etc.

4.Increased winds: Before rain, due to the influence of low pressure areas, the wind will increase, and lightning and thunder may also occur, which is also one of the signs of rain.

5.Aggravated plant odor: Before rain, due to the increase of negative ions in the air, the plants will release more volatile substances, making the plant odor in the air more intense, which is also a sign of rain.

6.Swallows fly low: Swallows fly high on sunny days, and when it is about to rain, they will fly low frequently.

7.Ant moving: Ants that live underground will move to higher places when they feel that it is going to rain so as not to be flooded by rain.

8.Frog croaking: Frogs are very sensitive to changes in air pressure, and when the air pressure becomes low and the air humidity increases, they will croak.

9.Long worm aisle: Snakes are also very sensitive to changes in air pressure, and before it rains, the air humidity increases and becomes stuffy, and snakes will burrow out of the ground to breathe.

10.Earthworm unearthing: Earthworms live underground, once the weather is about to rain, the heat and lack of oxygen will force them to climb out of the ground, so earthworms are unearthed, which is also a precursor to rain.

11.Fish jump out of the water: Before rain, the air pressure becomes lower, the air humidity increases, and the oxygen content in the water decreases, and the fish jump out of the water to breathe.

12.Dragonfly low: Dragonfly low-flying is a common pre-rain sign that usually occurs before a summer thundershower.

These signs may not always be present, but if several signs occur at the same time, it is more likely that it will rain.

The signs before rain are related to the weather conditions, and here are some common signs of rain:1The clouds thicken and darken:

When the cloud front in the air becomes thicker, it is often a sign of rain. This is because clouds block the sun's rays, making the sky darker. 2.

Humid air: Before the rain, the moisture content in the air will increase, making the air more humid. If you feel that the air is humid, it may mean that there is a higher chance of rain.

3.Change in wind direction: Before it rains, there is often a change in wind direction.

If you observe a noticeable change in wind direction, such as from northeast to south, it could mean that rain is more likely. 4.Temperature drops:

Before the rain, the temperature tends to drop somewhat. This is because clouds block the sun's rays, reducing solar radiation and causing the ground temperature to drop. 5.

Cloud shape: The shape and color of some clouds can indicate the possibility of rain on the Silver Mold Mountain. For example, if the clouds are dark gray or cloudy, this is often a sign of rain.

It is important to note that these signs do not completely** weather changes, because weather changes are very complex and changeable. If you need accurate weather forecast information, it is recommended to check the weather forecast of your local weather office.

Summary. The signs before rain vary depending on the region, season, and other factors, but here are some of the more common ones:

The signs before rain vary depending on the region, season, and other factors, but here are some of the more common ones:

1.Temperature drop: The air is humid before the rain, the temperature is relatively low, and there will be dew condensation on the surface of roads, buildings, etc., and the human body will feel cold.

2.Sky color changes: Before rain, the sky is often overcast, and the sky color changes from blue to gray.

3.Gradual change of wind direction: Before the rain arrives, it is common to change the direction of the prevailing wind in the early morning.

4.Snail infestation: Snails like damp and humid environments, and may laugh before the rain, and more and more snails even climb to high places such as the exterior walls of houses to rot.

5.Reduced bird activity: Due to the erratic weather, birds are often heard less before rain, or they are seen congregating and looking for shelter from the rain.

It should be noted that the above signs are all references, and there are no definite rules and standards. Therefore, if you want to confirm the signs before the rain in Chi Zheng, it is best to pay more attention to the local weather forecast and other channels so that you can prepare and arrange in advance.
