Weather refers to the atmospheric temperature of a place.

Weather refers to the atmospheric temperature of a place, as shown below:

Weather is the place where air temperature, rain, snow and wind change in a certain period of time.

The weather in different places at the same time may be different, and the weather in the same place at different times may also be different. The weather is constantly changing.

Weather phenomena are various natural phenomena that occur in the atmosphere, such as temperature, pressure, humidity, wind, clouds, fog, rain, flash, snow, frost, thunder, hail, haze and so on.

Extended data

Weather processes have different time and space scales, and large-scale weather processes are the background of small-scale weather processes, which restricts the development of small-scale weather processes.

For example, a large-scale precipitation weather process includes several small-scale local rainstorm weather processes. On the other hand, small-scale weather processes can also have a feedback effect on large-scale weather processes and change the process of large-scale weather processes.

In order to seek the evolution law of weather process, people often classify a certain kind of weather system or weather into one or several typical weather process models according to its characteristics of repeated development in history, such as frontal cyclone model, cold wave and hail weather process model.

Sometimes, a weather process model can be divided into several stages, such as the cold wave weather process model, which can be divided into three stages: brewing, development and outbreak. Comparing the development of actual weather process with typical weather process model, finding out the process similar to the model is helpful to make correct weather forecast.
