气候是指大气在太阳辐射、大气环流、下垫面性质和人类活动综合作用下,某一时期内大量天气过程的综合,和天气相比,具有相对的稳定性。太阳辐射是气候系统的主要能源,是形成气候最基本的因子。不同地区的气候差异及各地气候的季节交替,主要是太阳辐射在地表分布不均及其随时间变化的结果。
Climate refers to the atmosphere in the solar radiation, atmospheric circulation, underlying surface properties and human activities under the combined effects of a large number of weather during a comprehensive process, compared with the weather, with relative stability. Solar radiation is the main source of energy for the climate system and the most fundamental factor in climate formation. The climate differences in different regions and the seasonal alternation of the climate around each region are mainly the result of the uneven distribution of solar radiation on the surface and its change with time.
