Why can China forecast the solar eclipse every minute, but the weather forecast is very inaccurate!

The motion of celestial bodies has a definite orbit, and the influencing factors are very weak, so the gap between numerical prediction and actual position can be ignored. Even if the solar eclipse is predicted for thousands of years and tens of thousands of years, the minutes are not bad.

As for the weather, this is not the case. There are too many impressive factors. For example, the active Mediterranean cyclone may affect the activity of the south branch trough, leading to the strengthening of the southwest monsoon and the increase of water vapor in the middle and lower reaches of the Yangtze River, thus leading to rain and snow. As for the degree of influence that will appear in a few days, no one can say clearly how big it is. Natural, long-term weather forecast, just look around, don't take it seriously, the whole world is near.

For this rainy and snowy weather, my friends in Shanghai, Jiangsu, Zhejiang and Xiangjiang did not find any obvious mistakes in the weather forecast. Indeed, compared with winter, the weather is really better, just pay attention to the high-pressure movement in Siberia. Generally, the trend forecast for seven or eight days can ensure the intensity and influence range of cold air. I think the most likely reason is whether the landlord heard the gossip on the Internet. China Weather Network is a good website. Pay attention to it if you are interested.

I really don't trust. Know the clouds by yourself, watch the wind by yourself, and watch the radar chart by yourself. At least one or two days of trends and precipitation within a few hours can be clearly understood.
