The steps of making weather forecast are as follows

Making weather forecast mainly includes the following steps: data collection, numerical weather forecast, weather forecast made by meteorologists, weather consultation and release of weather forecast.

After the weather forecast is made, the Meteorological Observatory will announce it to the public through various channels. The main ways to spread weather forecast are TV, newspaper, internet, short message, weather telephone, etc. It will be the future trend to obtain weather forecast information through the Internet. Well-known weather forecast websites include Weather Online and China Weather Network.

Every day at any time, meteorological stations around the world will receive various weather records from weather stations. These records are collected into a huge database from which meteorologists get information. The organization that enables this information to be exchanged on a large scale is the Global Communication System (GTS). When data is input into a powerful computer, meteorologists can draw weather maps. Before making the weather forecast, they studied the weather map very carefully and compared it with the previous images. The accuracy of weather forecast in the next few days can even reach 85%.

Weather characteristics

Weather refers to the specific state of the atmosphere near the surface in a short period of time. Weather phenomenon refers to various natural phenomena in the atmosphere, that is, the comprehensive expression of the spatial distribution of various meteorological elements in the atmosphere (such as temperature, pressure, humidity, wind, clouds, fog, rain, flash, snow, frost, thunder, hail, haze, etc.). ) in an instant.

The weather process is the change process of weather phenomena with time in a certain area. All kinds of weather systems have certain time and space scales, and they are intertwined and influence each other. The combination of many weather systems constitutes a large-scale weather situation and hemispheric and even global atmospheric circulation. The weather system is always in the process of rebirth, development and extinction, and there are corresponding weather phenomena in different development stages.
