Jiujiang weather forecast 15-day forecast weather forecast accuracy?

The short-term weather forecast of 15 days is the most accurate. According to the radar and satellite detection data, the local strong storm system is monitored on the spot, and its future trend of 1-6 hours is predicted. The forecast for the next 3- 15 days mainly includes what kind of weather process is affected, whether there will be disastrous weather and the main weather change trend.

Trend method is to estimate the future position and intensity of various weather systems according to their past moving paths and intensity change trends on the weather map. This method is often not practical when the movement and intensity of the weather system have not changed suddenly, or when the weather system has not died, or when the weather system has changed suddenly or died.

15 weather forecast status

At present, the accuracy of our weather forecast is over 80%. Of course, this is a 24-hour forecast, and it is conceivable that the forecast for the next half month is very low. Resolutely give up the commonly used method at present, that is, take the old road of studying the atmosphere with poor memory function, and must take the astronomical road, because the driving force of atmospheric change comes from different positions of the major planets in the sun.

Only by understanding the law of this driving force and its relationship with rain or shine can we really provide it for mankind. This is why I think it is necessary to find a long-term weather forecast method from astronomy.
