Autumn begins this Monday in Brazil
Fall 2023 begins at 6:25 pm (Brasília time) this Monday (20th). The season is marked by milder temperatures and, during this period, rainfall is scarcer in the interior of Brazil, especially in the semi-arid northeastern region.
"It is considered a transition season between the hot and humid summer and the cold and dry winter, especially in Central Brazil," explained the National Institute of Meteorology (Inmet), in a statement.
It added that in the northern part of the Northeast and North regions, autumn is still a time for a lot of rain, especially if the Intertropical Convergence Zone persists further south of its climatological position for the period. This zone is the area where the trade winds converge, which blow from the tropics to the Equator region and, because they are very humid, cause rain in these surroundings.
At the other extreme, autumn is also characterized by the entry of cold air masses coming from the south of the continent, which cause the drop in air temperatures, especially in the South and part of the Southeast.
"It is also worth mentioning that during the season it is possible to observe the first formation of adverse phenomena, such as fog in the South, Southeast and Center-West regions; frost in the South and Southeast regions and in Mato Grosso do Sul; snow in the mountain areas and plateaus of the South Region, and cold in the south of the North Region and in the states of Mato Grosso do Sul, Mato Grosso and even in the south of Goiás," explained Inmet.
