一、影响日照时间长短的因素1.昼长;2.地势(地势高,日出早,日落晚,日照时间长);3.天气状况。二、影响太阳辐射强度的因素(即影响大气对太阳辐射削弱作用的因素)1.太阳高度(即纬度);2.天气状况;3.地势;4.空气密度。如为什么青藏高原太阳辐射最强?①纬度较低,太阳高度较大;②晴天多;③地势高;④空气稀薄,大气洁净。三、影响气温高低的因素1.纬度;2.地形、地势;3.下垫面性质(海陆位置、植被状况);4.天气状况。四、影响气温年较差的因素及变化规律1.纬度:低纬小,高纬大;2.下垫面性质;海洋小于陆地,沿海小于内陆,有植被的小于裸地;3.天气状况:云雨多的地方小于云
First, the factors affecting the length of sunshine 1. Day length; 2. Topography (high terrain, early sunrise, sunset, sunshine time); 3. Weather conditions. Second, the factors that affect the intensity of solar radiation (that is, the factors that affect the atmospheric attenuation of solar radiation) 1. The height of the sun (ie latitude); 2. The weather conditions; 3. The terrain; 4. The density of air. Such as why the Tibetan Plateau the strongest solar radiation? ① latitude is low, the sun is high; ② sunny days; ③ high terrain; ④ thin air, the atmosphere clean. Third, the factors that affect the level of temperature 1. Latitude; 2. Topography, topography; 3. The underlying surface properties (land and sea position, vegetation status); 4. Weather conditions. Fourth, the factors that affect the annual temperature difference and variation 1. latitude: low latitude and high latitudes; 2. underlying surface properties; the ocean is smaller than land, the coastal less than inland vegetation with less than bare land; 3. the weather Situation: clouds and rain are less than the cloud
