What is the difference between astronomical and meteorological stations? The portal gives answers.

As Meteorological stations are defined more practically and fixed, based on the civil calendar and climatological statistics. In the case of autumn, it starts on September 1 and ends on November 30.
These weather stations are defined based on temperature cycles and climatic patterns. They are important in the weather forecast: Allow a simpler and more consistent comparison of data over the years. The data is analyzed more clearly.
Each season always has three complete months, which facilitates analyzes and averages of temperatures, precipitation and other parameters.
And in recent days, there have been some normal changes at the beginning of the meteorological autumn: the days have begun to get shorter, the cooler nights, greater cloudiness, some northern rain – and of course, the eternal vision of the early leaves of the trees to fall.
