Hegang weather forecast accuracy 15 days

At present, the accuracy of Hegang weather forecast is above 80%.

Because people think that the driving force of atmospheric change comes from the different positions of the 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.

Forecast mode:

/kloc-before the 0/7th century, people made weather proverbs by observing the changes of astronomical phenomena and celestial bodies, thus predicting the local future weather. /kloc-after the 0/7th century, meteorological observation instruments such as thermometers and barometers appeared one after another, and ground weather stations were established one after another. At this time, the weather is mainly predicted according to the changes of single station pressure, temperature, wind and cloud. ?

185 1 year, Britain sent observation data by telegraph for the first time, drew weather map on the ground, and made weather forecast according to the weather map. Since the 1920s, air mass theory and polar front theory have been applied to weather forecast.

In 1930s, the invention of radiosonde, the appearance of high-altitude weather map and the wide application of long-wave theory in weather forecast made the analysis of weather evolution develop from two-dimensional to three-dimensional. In the late 1940s, the application of weather radar provided an effective tool for forecasting precipitation, typhoon, rainstorm and severe storm.
