Brazil has a wide range of climates due to its extensive territory (8.5 million km2), the diversity of relief forms, the altitude and dynamics of air currents and masses.
About 90% of the Brazilian territory is located between the tropics of Cancer and Capricorn, which is why we use the term "tropical country".
Crossed in the north by the Equator Line and to the south by the Tropic of Capricorn, most of Brazil is located in low latitude zones, where hot and humid climates prevail, with average temperatures around 20ºC.
The types of weather
The classification of a climate depends on several factors, such as temperature, humidity, air masses, atmospheric pressure, sea currents and winds, among others. The most commonly used classification for the different types of climate in Brazil resembles that created by Arthur Strahlerbased on the origin, nature and movement of air currents and masses.
The most directly interfering air masses are known to be equatorial (continental and atlantic), tropical (continental and atlantic) and polar atlantic.
Thus, they are verified in the country from hot humid climates, coming from the equatorial masses, as is the case of much of the Amazon region, to very strong semi-arid climates, typical of the northeastern backwoods. So, we have, as main Brazilian climate types:
- Wet equatorial
- Semi-Equatorial Equatorial
- Altitude Tropical
