O spring marks the arrival of the new station in the southern hemisphere of the planet, with winter coming to an end exactly to 15h19 (Brasília time) this Monday (22).
In the northern hemisphere, the date marks the beginning of autumn and late summer.
For us, has been bringing higher temperatures and longer dayswith more hours of sunlight.
Os equinoxes They occur twice a year to mark the arrival of spring and fall. On these occasions, just like this Monday, day and night usually have the same duration of 12 hours eachdue to the sun’s rays that reach the earth more directly on the equator line – the word “equinox” even comes from the Latin “equinoxium”, whose meaning is “equal night”.
What happens during the equinoxes?
The earth revolves around itself along an imaginary line that goes from the north pole to the south pole, and it is this rotation that gives us the day and night. But the rotation happens on an inclined axis at 23.5 degrees, which causes one hemisphere on the planet to receive more sunlight than the other for half the year.
It is this difference in the inclination of the planet that causes sunlight to be more in the north or more in the south. Equinoxes happen in a moment of “balance,” when sunlight focuses almost the same way in the two hemispheres.
The maximum effect of this inclination is felt at the end of June and late December, during the solstices, when the differences between the time of day and night are higher, marking the arrival of summer or winter.
