Was there only one kind of weather before the earthquake?

Meteorological anomalies People often describe earthquake prediction technicians as "managing the sky, the ground and the air in the middle", which really makes sense. Before the earthquake, the weather often appeared abnormal. There are mainly sultry before the earthquake, anxiety and irritability, long drought or continuous rain, yellow fog scattered, dark sunshine, strange wind raging, hail (flying snow) in June and so on. For example, the ray cloud: the cloud will be a long ray in the sky, and the position where the center of the ray points is the position of the central earthquake. Such a Lei Yun is easily observed by people. Earthquake cloud: Earthquake cloud is a kind of cloud body that indicates earthquake in non-meteorological classification. Before the earthquake, the color of clouds was: white, gray, orange or orange. Characteristics of earthquake clouds: strong winds are not easy to change its shape, there is a clear dividing line between the sky and clouds, and there are many waves. There are two theories about the formation of earthquake clouds: heat theory: when an earthquake is about to happen, a large amount of heat is generated because geothermal energy gathers on the earthquake zone or because rocks on the earthquake zone rub violently under the action of strong gravity. These heat overflows from the surface, heats the air, produces updraft, and forms an "earthquake cloud" at high altitude, and the tail end of the cloud points to the place where the earthquake occurs. Electromagnetic theory: before the earthquake, the rock appeared "piezomagnetic effect" under the action of geostress, which caused local changes of geomagnetic field; In-situ stress makes rocks compressed or stretched, causing changes in resistivity and local changes in electromagnetic field. Due to the influence of electromagnetic waves on the upper ionosphere, the plasma concentration in the ionosphere drops sharply, which makes water vapor and dust arrange in an orderly and non-free manner, thus forming earthquake clouds. Briefly analyze the detailed form of the earthquake cloud: if the length of the earthquake cloud is very long, the closer it is to the time of the earthquake; If the color of the earthquake cloud looks deep, the depth of the corresponding earthquake is deep; If the earthquake cloud lasts for a long time, the closer the corresponding epicenter is; If the color of the earthquake cloud is gray, it means that the earthquake is serious.
