How do I predict the weather?

Forecast the weather

According to the sensory system of animals, we can predict the weather by observing the whereabouts of some animals: swallows flying low, frogs croaking, ants moving, etc. Because animals are sensitive to air pressure and humidity, they feel anxious when they feel abnormal. Can reflect the change of the weather at that time.

You can also observe the thickness and color changes of clouds to make predictions. How much rain falls from the clouds and when it rains are observed from the clouds. When the cloud is as small as a fish scale, it means that the weather will change. The agricultural proverb says that "fish scales are the sky, there is no rain and the wind is crazy", which describes the thistle.

Weather radar can also be used to predict weather radar (Doppler radar) is mainly used to detect precipitation. The weather radar emits pulsed electromagnetic waves. When electromagnetic waves meet raindrops, a small part of energy is scattered by raindrops, and then it reaches the radar antenna and is received by the radar.
