Maximum and minimum temperatures in weather forecast

Here's the thing. Because of the relationship between clouds, geography and the surface, the temperature of a day is different from place to place. There will be a maximum temperature and a minimum temperature every day. As mentioned in the weather forecast just now, this temperature is basically the air temperature within 2 meters of the surface.

Because the specific heat of land in inland cities is less than that of water, and the temperature difference between seasons is greater than that in coastal and island cities, the existence of clouds will greatly affect the minimum temperature at night.

Generally speaking, the sun is strongest at noon 12, but it is not the hottest at this time of day, but after two hours, the surface temperature will gradually reverse. Note that this refers to the geographical difference 12, and it is not the coldest time when the light is weakest at night, because the clouds at night will reflect the ground temperature to ensure a certain degree of inversion, basically.
