一、太阳直射点与太阳高度变化规律 太阳光线对于地平面的交角叫做太阳高度角。简称太阳高度。地球是个球体,任何时候各纬度太阳高度不同。又由于黄赤交角的存在及地球公转时地轴的指向不变,引起太阳直射点的南北移动,所以各纬度太阳高度又有季节变化。 无论是纬度分布规律还是季节变化规律,只要抓 First, the sun’s direct point and the change of the height of the sun The intersection of the sun’s rays with the ground plane is called the solar altitude angle. Referred to as the height of the sun. The earth is a sphere. At any time, the altitude of the sun is different at different latitudes. Because of the existence of the yellow cross angle and the orientation of the earth’s axis during the earth’s revolution, the north-south movement of the sun’s direct point is caused. Therefore, the solar altitude at each latitude has seasonal changes. Whether it is the latitude distribution law or the seasonal variation law,
