The weather in the morning and evening
First of all, we all know that the weather has a great influence on the temperature in an area, and the most direct influence factor of the weather is the deep forest plants. We live in a city, and the temperature is relatively stable every day, because these trees in the depths of the forest in the city save energy for us and prevent heat from escaping. When the sun comes out during the day, they can feed back heat into the air at night. Although there is a lot of energy loss, at least they can guarantee the city.
But there are no trees in the desert, and there are no objects to keep heat. The sun is very strong in the morning, and the temperature is naturally high. The sand is too soft to cool down, so it is naturally cold at night. Another point is the specific heat capacity. There are few green plants in the desert area, which are basically endless sand, which leads to the fact that the specific heat capacity of the whole desert is very low and the energy that can be stored is also very low.
We can simply think of this specific heat capacity as charcoal. We all know that charcoal releases heat when it burns. This is because it stores energy and releases energy when burning, and the amount of energy released under the same area is the specific heat capacity. The specific heat capacity of the desert is very small, and the solar heat stored in a short time is very small, so the sun is gone at night, and the natural weather is very cold, which is the reason for the great temperature difference between morning and evening.
