Autumn’s first weekend in Brazil promises to bring significant changes in the climate, with the return in the mornings and rain in much of the country. Pedro Côrtes expert in climate and environment, detailed expectations for the transitional period between summer and winter.
According to Côrtes, the phenomenon La Niña It is weakened, which should influence weather conditions in the coming months. “We are really going through a transition phase, not just because it is the fall, which is the transition between summer and winter, but also because the La Niña phenomenon is already well weakened,” he explained.
Above average and temporal temperatures
For April, May and June, the forecast is above average temperatures. However, Côrtes points out that we should not expect hot waves as intense as those recorded last year. “We expect above average temperatures, eventually a heat wave for a few days, but nothing as intense as it was last year, or even in February this year,” said the expert.
The south of the country, especially Rio Grande do Sul, should face temporal in April. These rains, however, will be concentrated and not necessarily well distributed, which may not be favorable to agriculture. Already in May, the forecast is of below average rainfall in the Southeast and Midwest, with a return to normal in June.
Impacts of climate change
Côrtes warned of the effects of climate change on weather standards. “With climate change, we have a situation where events that once occurred with a certain regularity are more frequent and also gain in intensity,” he explained. This means that rare phenomena can occur more often, and rains tend to be more intense and localized.
This trend has challenges for the very short -term meteorological forecast and can affect various sectors, such as agriculture. “Sometimes it rains a lot intensely in one area, and the next door does not rain. This, for example, for agriculture is terrible,” said the expert.
With these perspectives, the population should be aware of local predictions and prepare for possible sudden variations of temperature and precipitation along the season.
