SAO PAULO, Oct 8, 2021 (BSS/AFP) - Unusually powerful sandstorms have left
at least six people dead in Sao Paulo in recent weeks, local media said, as
southeastern Brazil grapples with severe drought.

  Scenes of huge orange dust clouds rumbling across the countryside -- with
winds of up to 100 kilometers (62 miles) an hour -- have been seen at least
three times since the end of September, terrifying residents in urban and
rural areas of Sao Paulo and Minas Gerais states.

  The six people killed in Sao Paulo were victims of falling trees and houses
and other direct consequences of the storms, local media reported.

  "In some ways, they're a common occurrence, but not of this magnitude that
we've seen in 2021," meteorologist Estael Sias of the Brazilian weather
channel Metsul told AFP of the storms.

  "It's the result of a long period of a lack of rain, high temperature and
low humidity," she explained.

  After the dry season, rain arrives, usually accompanied by wind storms.

  "The wind gusts come in contact with the sandy ground and churn up into the
atmosphere pollution, waste and the leftovers from fires, which also happen
during the dry period," Sias said.

  The strong storms "can't be separated from climate change," he said.

  "In this century, every year has had record temperatures. There is more
heat in the atmosphere, which has just been transformed into energy for
extreme (weather) events: rain, storms, floods, but also drought, cold and
heat, what has just been unleashed with events like these dust storms," Sias
said.

  Such storms, which can be frequent in desert regions, can reach thousands
of meters into the sky, be up to 160 kilometers wide and last for several
hours, according to Sias.

  In addition to dealing with extreme drought, the mostly agricultural region
also has large open areas uncovered by vegetation, which also leaves land
vulnerable to soil being caught up in high winds.

  Brazil is facing its worst drought in 91 years, which has led to a
critically low water level in hydroelectric reserves in the central-western
and southern parts of the country, driving up electricity costs.
