What are the signs of rain and thunder in winter?

The signs of rain and thunder in winter are climate change, early warning of natural disasters, the influence of agricultural production and so on.

1, climate change

Rain and thunder in winter are usually caused by climate change. When cold air and warm and humid air meet and interact, thunderstorm weather may occur. This climate change may be caused by atmospheric circulation adjustment, pressure fluctuation, typhoon and other factors.

2. Early warning of natural disasters

Rain and thunder in winter may be an early warning of natural disasters. For example, thunderstorm weather in some areas in winter may be accompanied by extreme weather phenomena such as blizzard and freezing rain, which will affect traffic, electricity and communication, and even lead to casualties and property losses.

3, the impact on agricultural production

Rain and thunder in winter also have a certain impact on agricultural production. In winter, crops in many areas have entered a dormant period. At this time, if there is thunderstorm weather, it may have an adverse impact on crop growth and yield. In addition, thunderstorms may also cause floods, mudslides and other disasters, posing a threat to agricultural production.

Signs before rain and thunder:

1, the sky darkens: Before a thunderstorm comes, the sky often becomes gloomy and the light darkens. This is because the clouds become thicker and block the sun.

2, cloud thickening: the clouds in the sky will gradually thicken, which is a precursor to thunderstorm weather.

3. Increased wind power: The wind power tends to increase, especially in coastal areas, which may indicate that a storm at sea is coming.

4. Temperature drop: Before a thunderstorm, the temperature often drops, because clouds block the sunlight and lower the ground temperature.

5. Humidity increase: Humidity will gradually increase because the water vapor in the cloud is gathering.

6. Frequent lightning: Before the thunderstorm comes, lightning may appear frequently because the charges in the clouds are accumulating.

7. Thunder rumble: Before the thunderstorm comes, you may hear thunder rumble, because the charges in the clouds are being released.

8. Air pressure change: As the air flow in the atmosphere is adjusted, the air pressure may change.
