Description method of climate characteristics

Description method of climate characteristics:

1. If you describe the characteristics of a certain climate type, you can qualitatively describe it from two aspects: temperature and precipitation in the whole year or in winter and summer.

2. If we only describe the characteristics of temperature or precipitation in a certain place, we should generally describe it qualitatively and quantitatively from the aspects of numerical value and seasonal variation.

3. If we analyze the influence of climate characteristics in a certain place on agricultural production, it is generally summarized as the coordination degree of rain and heat, heat level, winter temperature, light intensity, total precipitation and seasonal (interannual) changes.

Brief introduction of weather:

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.
