What is the temperature in the weather forecast? Is it surface temperature or atmospheric temperature?

The temperature reported in the weather forecast is the air temperature. After the heat energy of the sun is absorbed by the ground, the ground transfers the heat to the air through radiation, conduction and convection, which is the main source of heat in the air. but

The part directly absorbed by the atmosphere has little effect on heating air, and can only increase the temperature by 0.0 15 ~ 0.02℃. It is also for this reason that, generally speaking,

Will be higher than the temperature.

Many factors will change, such as surface humidity, temperature,

, surface materials (such as lawn or bare ground, or cement floor, or

) and so on. For a region, the surface temperature of the region mainly depends on the latitude of the region (such as the equatorial and arctic regions)

There is a temperature difference of tens of degrees in the region), as well as altitude difference, population density, industrial development and forest coverage (like desert areas at a latitude and

The temperature difference between regions is also great).
