Why is it always cloudy and even raining cats and dogs during earthquakes? Any explanation?

The atmospheric phenomena before the earthquake include obvious changes in temperature, humidity and pressure field such as atmospheric turbidity, haze, fog, heavy snow and dust fall. There are many reasons for climate anomalies, and earthquake preparation is one of the possible reasons. But there is no conclusive evidence to prove that earthquakes and climate anomalies are necessarily related. There are many factors that affect the climate. Even the same climate phenomenon is mostly caused by different factors. Therefore, it is unfounded to say that a particular climate phenomenon has something to do with earthquakes. If there is a climate anomaly, it cannot be said that there will be an earthquake in the future, and the climate anomaly is not necessarily caused by a major earthquake.
