Brazil Barometric Pressure Map
Depending on how many places we monitor in Brazil, the map displays a sampled set of barometric pressure data to give a clear overview of current conditions.Weather Systems
Several weather systems change air pressure in Brazil. The South Atlantic Subtropical High brings dry, stable air along the coast. The Amazon Low occurs from intense heating over the rainforest, drawing moist air and causing rain. Cold fronts from the south often bring sudden drops in pressure and storms.
Geography
Brazil's geography plays a big role in pressure. The Amazon Basin in the north is flat and hot, so air pressure drops there as warm air rises. The highlands in the southeast and central regions experience more stable, higher pressure. Mountains block or redirect wind and affect how weather systems move.
Seasonal Cycles
During the wet season in summer (December to March), pressure in the north and west of Brazil is usually low because the land heats up, causing rain and thunderstorms. In the dry winter (June to August), high pressure builds, blocking rain and bringing drier, cooler air, especially to the south and central regions.
Climate Change
Climate change could change these pressure patterns. Rising temperatures may lower pressure in the Amazon, bringing heavier rain and longer wet seasons. High-pressure systems might get stronger or shift position, which can cause more frequent droughts in some areas and extra rain in others.
