What is the temperature error of rivers, land and air in one day in the same area?

What you want to say is the difference between the three! Error refers to the difference between the measurement accuracy of the instrument and the actual situation.

Then the answer to this question is not necessarily. The general weather forecast temperature refers to the temperature without direct sunlight 1.5m above the ground.

Land temperature is related to the color and material of the ground, whether it is directly irradiated by the sun, and air mobility.

Generally, taking summer afternoon as an example, the highest surface temperature in Turpan can be about 35 degrees higher than the temperature. The southeast coast is generally about 25 degrees high.

Food baked with aluminum foil. This is feasible on land. But the problem is that aluminum foil can't cover the road normally.

Water is special, and the temperature of groundwater is basically unchanged. Surface water changes with temperature, but the change range is worse than that of temperature (the peaks and valleys are also behind the temperature). However, it can be approximately estimated that the difference between the water temperature and the highest and lowest temperature is close to the difference between the average temperature and the highest and lowest temperature.
