Why is the summer weather in Zaozhuang cooler than in previous years? Does it have anything to do with the eclipse?

It has little to do with the eclipse. Although the sun will be "swallowed up" by the moon on the morning of the 22nd, the instantaneous temperature will not change much. Where the total solar eclipse occurs, the temperature people feel may drop by 3℃-4℃. In Shandong, because it is a partial solar eclipse, the temperature change is even less obvious and almost imperceptible. The summer weather this year is cooler than in previous years, which may be caused by unstable climate change. It is also reported that the solar eclipse may only have an impact at that time and will not last for a long time.
