Why do meteorological observation stations and duty rooms have to be separated by a certain distance, and there are many open spaces around them?

In order to make a correct weather forecast, we must first master the original appearance of the air, so we must avoid the influence of the environment. This requires that the observation site is empty and the air can circulate freely.

Secondly, at the observation site, it is necessary to measure sunshine, ground temperature, wind force and rainfall. In order to prevent the sun from being blocked and the wind and rain from being blocked by the surrounding buildings, the surrounding area needs to be open.

Third, in the field of observation, it is necessary to observe clouds and visibility, as well as weather phenomena in the distance. If there are many buildings around, it is impossible to observe these phenomena.

Therefore, in order to make correct weather forecast, it is necessary to set up meteorological observation fields in the surrounding open places.
