El Niño e La Niña: entenda de uma vez

Por: Professor Leandro Sinis

El Niño e La Niña são fenômenos ligados ao aquecimento ou resfriamento anormal do Pacífico Equatorial e alteram padrões de clima.

Quando a temperatura do oceano muda, também podem mudar a circulação atmosférica, os ventos e a distribuição das chuvas.

No El Niño, as águas superficiais do Pacífico Equatorial ficam mais quentes que o normal, modificando a circulação do ar.

Na La Niña, as águas superficiais do Pacífico Equatorial ficam mais frias que o normal, produzindo efeitos climáticos diferentes.

Esses fenômenos podem alterar o regime de chuvas e temperaturas no Brasil, mas os impactos não são iguais em todas as regiões.

El Niño e La Niña são fenômenos naturais de variabilidade climática. Já o aquecimento global envolve uma tendência de longo prazo.

El Niño e La Niña alternam-se de forma irregular, separados por períodos neutros. Cada episódio pode durar vários meses.

El Niño = aquecimento anormal. La Niña = resfriamento anormal. A partir disso, fica mais fácil entender seus efeitos no clima.
