What's the difference between "meteorology", "weather" and "climate"

Differences between meteorology, weather and climate;

1, meteorology

In layman's terms, it refers to all atmospheric physical phenomena such as wind, clouds, rain, snow, frost, dew, rainbow, halo, lightning and thunder.

2. Weather

Weather refers to the specific state of the near-surface atmosphere in a short 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.

3. Climate

Climate is the long-term average state of atmospheric physical characteristics. The science of studying climate is climatology. Time scales are months, seasons, years, years to hundreds of years. Climate is measured by the characteristics of cold, warm, dry and wet, and is usually characterized by the average value and deviation value of a certain period.
