If you ask any of us when autumn begins, the answer is clear: November 22, with the equinox. It is not incorrect, but we must specify that we are talking about the astronomical autumn. And it is that, the climatological autumn begins on September 1 and ends on November 30 . But what is the difference between the two autumns?
Climatic autumn and astronomical autumn
The climatological autumn, also known as meteorological autumn , begins on the first day of the month, that is, on September 1, this Wednesday. This is so because, due to the inertia of the atmosphere, the highest temperature in summer is usually recorded in mid-July, in the same way that the lowest temperature in winter is reached in mid-January.
Taking into account that the equinoxes and solstices do not always fall on the same date, if they are studied in this way the data for each season are more precise , according to meteorologists.
Meanwhile, the astronomical autumn begins on September 22, 2021 . On this date the autumnal equinox takes place, when the Sun hits the line of the equator directly. Thus, the northern and southern hemispheres receive exactly the same amount of light, and the day and night last the same.
From the autumn equinox, the days begin to get shorter and longer, until the winter solstice arrives, when the longest night of the whole year occurs.
Autumn curiosities
As a result of the explanation of what the climatological autumn is , it is worth knowing a series of curiosities about this season of the year.
Did you know that in autumn it is easier to gain weight ? Unlike spring and summer, people are deficient in vitamin D from lack of sunlight. This makes it harder for the body to break down fats.
In autumn the so-called “Harvest Moon” takes place . It receives this name because, in ancient times, the peasants took advantage of this day to collect the crops.
Autumn begins on September 22 or 23, although there are times when it does on the 24th. However, it is a very strange phenomenon, which will not be repeated until the year 2303 .
And finally, it should be noted that, based on various studies, people born in the fall live longer .
