Weather forecast all over the country

The weather forecast for all parts of the country is as follows:

The main contents of weather forecast are the future rain, maximum and minimum temperature, wind direction and wind force and special disastrous weather in a region or city.

As far as China is concerned, meteorological stations can accurately predict the location and intensity of natural disasters such as cold waves, typhoons and rainstorms, and can directly serve industrial and agricultural production and people's lives. With the development of productive forces and the progress of science and technology, the scope of human activities has been expanded unprecedentedly, and the impact on nature has been increasing, so weather forecast has become an indispensable and important information in modern society.

Weather forecast judgment method:

Also known as trend method, it infers 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 effective when the movement and intensity of the weather system do not suddenly change, or when the weather system does not regenerate or die. However, when it suddenly changes or the weather system is alive or dead, the forecast is often not realistic.

Similar situation method, also known as pattern method, is to find some similar weather situations from a large number of historical weather maps and summarize them into certain patterns. If the current weather situation is similar to that before a certain model, it can be predicted with reference to the later evolution of the model. Because similarity is always relative and can't be exactly the same, this method often leads to errors.
