Why is the weather cold in winter?

The temperature of the weather is related to the angle of the sun shining on the earth and the amount of heat it irradiates: when the sun is at a vertical angle to the ground, the sun heats the ground to the highest temperature, and as the slope increases, the temperature increases. decline. In winter, the intensity of the sun's rays is relatively weak, and of course the temperature will not rise. The place we are in is the northern hemisphere of the earth, a temperate zone. In winter, the sun's tilt to the ground is the largest, so the heat on the ground is also the lowest and there is less heat. Therefore, we feel very cold.
