一、气候形成因子和特点一个地区的气候,是在多种因素的共同影响下形成的。 1.太阳辐射:这是最基本的原因。它决定不同纬度地带,受太阳辐射在地表分布的影响,气温一般是随纬度增高而降低,故热带的4种气候类型都有“终年高温”的特点,而极地气候则“终年低温”。 2.大气环流:影响气候的降水状况。 I. Climate-forming factors and characteristics The climate of a region is formed under the combined influence of various factors. 1. Solar radiation: This is the most basic reason. It determines the location of different latitudes. Affected by the distribution of solar radiation on the surface, the temperature generally decreases with increasing latitude. Therefore, the four climate types in the tropics have the feature of “high temperature” throughout the year, while the polar climate is ". 2. Atmospheric circulation: precipitation conditions that affect the climate.
