After a dry winter, spring, which begins at 5:02 pm this Friday (22.09), should bring higher temperatures and a little more humidity at the end, although the weather will remain dry in the first few days. The season begins without the influence of El Niño or La Niña phenomena, being marked by climate neutrality.
The tendency is for the La Niña phenomenon to occur throughout the spring and summer of 2017 and 2018. Unlike El Niño, the phenomenon consists of a decrease in the temperature of the Pacific waters. According to INMET – National Institute of Meteorology meteorologist, Luiz Renato Lazinski, the phenomenon is expected to influence the climate throughout the summer harvest.
This year's spring should also end with the phenomenon of the South Atlantic Convergence Zone (ZCAS), which provides voluminous rain to several regions of the country.
The season's increased heat and humidity cause rain showers in the late afternoon or evening in the Central-West and Southeast regions. The season also brings little change in monthly rainfall numbers in the South region. In the North and Northeast regions, there is usually little variation in temperature.
For the center-south of Brazil, rainfall is expected to continue showing irregularity in distribution, interspersing periods of heavy rainfall and some with little volume or even none at all.
Temperatures in spring still continue to show wide variations, with no late cold that could harm agriculture. During the summer temperatures return to normal, without major variations.
For areas north of the central-west region and grain-producing areas of northeastern Brazil, the rains that are delayed should be more regular and abundant.
For spring 2017, strong polar masses are not expected. Therefore, we should not have atypical cold events like last year.
