一、利用等温线图判断南、北半球1.判读规律由于太阳辐射受地球球体形状的影响,从地球赤道向两极递减,导致低纬度地区获得太阳辐射的能量多,气温就高;高纬度地区获得太阳辐射的能量少,气温就低。所以,在世界等温线分布图上,气温大致是从低纬向两极递减。据此可归纳如下规律: First, the use of isotherms to determine the southern and northern hemispheres 1. Interpretation of law As the impact of solar radiation by the shape of the Earth’s globe, decreasing from the Earth’s equator to the poles, resulting in low latitude solar radiation to obtain more energy, the temperature is high; access to high latitudes Solar radiation less energy, the temperature is low. Therefore, in the world isotherm map, the temperature is generally decreased from low latitudes to poles. According to this law can be summarized as follows:
