A severe heatwave, characterized by a “heat dome,” is predicted in Brazil, pushing temperatures potentially to 45°C.
This is expected to last for multiple consecutive days. The shift will influence weather in Argentina, particularly in the north and bordering countries.
Initially, Argentina had a cold atmosphere this week, but that’s about to change.
A pulse of warm air will elevate temperatures beyond 30°C in areas such as Formosa, Santiago del Estero, and the eastern strip of Salta and Jujuy.
Moreover, extreme highs of 40°C might be recorded in the far north.
This extreme weather will not just impact Argentina but also neighboring countries like Paraguay, southern Brazil, and Bolivia.
If the heatwave materializes, the central Amazonia in Brazil could experience record-breaking heat for September.
The event is expected to span about eight days, affecting central regions of Latin America and surrounding areas. It’s linked to a significant atmospheric blockage.
Various climatic parameters influence rising temperatures in the region.
These include gradual warming of Equatorial Pacific waters, often related to the El Niño phenomenon.
Global warming also plays a part, along with shifts in atmospheric patterns, as pointed out by experts.
In the coming days, the epicenter of this extreme heat will be located in central and southern Brazil.
Here, the mercury could soar between 38°C and 45°C. Nearby countries like Paraguay, Bolivia, and the extreme north of Argentina will also be affected.
Experts conclude that this heat event could be a harbinger of a scorching season to come in the southern hemisphere.
Background
Adding context and analysis, this looming heatwave signals a troubling start to the warm season in the southern hemisphere.
It poses critical challenges, not only to public health but also to the environment.
Increased temperatures amplify wildfire risks, putting enormous stress on already fragile ecosystems. The impending heatwave in Brazil is therefore with a wider impact.
Moreover, high heat and low humidity create a health hazard, affecting the young and elderly most severely.
