Is there an early warning of the weather before the earthquake?

Looking up at the sky and overlooking the earth, there is a connection between the changes of heaven and earth. Our people have long noticed some meteorological anomalies before strong earthquakes. Some phenomena described in the historical documents of China before the earthquake, such as "the earth is gloomy and the sky is foggy", "the sky is gloomy and the moon is dim", "it's not cold at night, the sun is red as blood" and "it's sweltering and people can't sleep", all belong to the meteorological precursors of the earthquake. People have successfully predicted some earthquakes by using this precursor. Scientists and technicians have conducted in-depth investigation and study on the relationship between meteorology and earthquakes, and obtained some preliminary understanding. 1) Some earthquakes are closely related to the movement of strong cold air masses. 1May 1967 1 1 An earthquake of magnitude 6.2 occurred in northwest China, which occurred after a strong cold air moved westward from Almaty and the air pressure changed greatly. 2) Significant warming (or cooling) of the climate in the earthquake zone may also be a precursor of strong earthquakes. Before1954 February1/Gansu Shandan earthquake with magnitude 7 and 1975 Haicheng and Yingkou earthquakes, the temperature also became particularly warm. However, about 20 days before the Xingtai earthquake in March 1966, the local temperature dropped to the lowest point in more than a decade. 3) Floods, droughts or rainstorms that have not happened for many years are the most prominent. 1963 The largest flood occurred in Xingtai, Hebei Province, and 1964 suffered from waterlogging for more than 40 days. 1965 saw a drought that had never happened in decades, and then 1966 saw a strong earthquake. 1970 The Tonghai earthquake in Yunnan also occurred after the flood and drought disasters. 1975 before the Haicheng and Yingkou earthquakes, there was a lot of rain in the autumn of the first year. According to historical records, there were droughts and floods before 1830 in cixian earthquake, Hebei province and 1889 in Daming, Hebei province. To sum up, there are two kinds: waterlogging-drought-earthquake and drought-waterlogging-earthquake. The above-mentioned meteorological anomalies before the earthquake provide a certain basis for short-term and medium-term earthquake prediction. However, there are many factors that cause meteorological changes, so not every specific meteorological change can stimulate the occurrence of strong earthquakes, and not every strong earthquake is preceded by meteorological anomalies. In practical work, it is necessary to distinguish the meteorological anomalies before the earthquake from the normal meteorological development process in order to get better results.
