Science and Technology

A cold air mass gains strength, turns into a cold wave, and could drop temperatures in the South and Southeast for several days, with a peak between May 12 and 13, advancing close to the central region of Brazil, and a risk of storms before the weather change.

Science and Technology

A mass of polar air is crossing Southern Brazil towards the Southeast and will cause something meteorologists call a thermal shock; the temperature could drop 10 degrees in just a few hours, and anyone who isn’t prepared will be caught completely by surprise.

A monstrous cold air mass will sweep half of Brazil in seven days with sub-zero temperatures, frosts from Rio Grande do Sul to Paraná, a historic cold snap in the Amazon, and a real possibility of snow falling in the South of the country for the first time in 2026.

Science and Technology

A new cold air mass invades Brazil from the ocean with wind gusts of 60 kilometers per hour, drops temperatures to near zero in the South, causes frost in dozens of cities, and reaches São Paulo and Rio de Janeiro right after days of intense heat.

Interesting facts

A cyclone arrives in Brazil with gusts of up to 60 km/h, dropping temperatures, intensifying the thermal sensation, and advancing with a cold air mass; high pressure brings even colder dawns until May.

Interesting facts

The first winter cold spell is coming with an air mass at 2°C at 850 hPa, gusts of up to 70 km/h, and lows of 0°C to 5°C, with potential for frost for 3 consecutive days in Southern Brazil.

Get your heavy coat ready: an extratropical cyclone will create a corridor of cold air that hits Rio Grande do Sul starting Sunday with winds of 70 km/h, widespread frost between Tuesday and Wednesday, and a risk of rough seas on the Rio Grande do Sul coast during the week.

Science and Technology

An intense mass of cold air is already scheduled to lower temperatures in Brazil starting on April 25, and the peak of the cooling on Tuesday, April 28, could bring thermometers below 10 degrees in several cities in the South, with an advance into the Southeast.

Science and Technology

The south of Brazil records the first frost of 2026 with the advance of a cold air mass, while storms gain strength, raising the risk of rainfall above 120 mm and triggering alerts in agribusiness.

In the cold desert of Ladakh, where it hardly rains, engineer Sonam Wangchuk created the ice stupa, a tower that freezes winter water and stores it for irrigating crops in the spring, a simple engineering feat that mimics nature.

Almost 6,000 residents live concentrated along a single street nearly 9 km long in the interior of Poland. Houses form a continuous row, and behind them, narrow agricultural strips emerge, creating one of the most unusual rural patterns in Europe.

Júlia Pimentel, an 11-year-old from Minas Gerais, independently invented a new formula to calculate the square root using simple addition and multiplication, and her method was published in one of the most important mathematical scientific journals in Brazil.

They planted a sea of eucalyptus to produce cellulose, but the monoculture turned into a green desert, dried up springs and rivers, and pushed families out of regions in Minas Gerais and Bahia.

Chinese woman planted trees for decades while sand buried part of her house, received $5,000 from an American in 1999, and helped transform the desert into a forest of 8 million trees in China.

Heir bought 23,000 degraded acres in the Scottish Highlands, fenced the area, planted nearly 1 million native trees, and transformed empty mountains into a forest officially recognized after meeting 15 evaluation criteria over 20 years.

The Atacama Desert, the driest place on Earth, was covered in flowers and turned into a colorful carpet with more than 200 species in the phenomenon called “desert bloom,” when atypical rains awaken seeds that had remained dormant in the soil for many years.
