Abnormal July 2021: record heat in the Northern Hemisphere and record cold in the Southern Hemisphere of the Earth.
In Brazil, snow fell and the air temperature was the lowest in 65 years, with severe frosts destroying crops of sugar cane, coffee and corn. “In more than 30 years of weather forecasting in Rio Grande do Sul, we have never seen horizontal snow with such strong winds and severely limited visibility. This is what North Americans call a blizzard,” MetSul reports.
Record frosts were recorded in the central part of the Republic of South Africa (RSA). Snow also fell in different parts of the country. In particular, the temperature in the city of Kimberley and surrounding areas reached -9.9 °C. Forecasters noted that such low temperatures have not been recorded in the entire history of meteorological observations.
On Sunday, July 11, in Death Valley (California, USA) the air temperature was recorded at +54 °C. Meanwhile, sunshine temperatures in Kuwait rose to an extreme 70°C. At the same time, +53.3 °C was recorded in the shade. Thus, this can be considered the hottest summer in the Middle East emirate in the last 70 years.
Dozens of people died in Canada during an unprecedented heat wave that broke temperature records, with thermometers hitting 49.6C in Lytton, British Columbia, for three straight days.
According to biologists, millions of marine inhabitants – mussels, starfish, crustaceans – died as a result of the anomaly. Experts are also concerned about the condition of fish in inland waters, reports Inopressa.
Last year, scientists wrote about a heat wave in the coldest place on Earth – Antarctica. It’s all about atmospheric and ocean processes – for three days in February 2020 in the area of the Australian research station Casey, where the temperature never rose above zero, thermometers recorded from 7.5 to 9.2 degrees Celsius, and at Davis station, located in one of the driest places on the icy continent, it rained for the first time, reports ria.ru. Scientists at the University of Bern have calculated that the likelihood of heat waves has increased 20-fold in recent decades. One of the most common reasons is blocking anticyclones in the atmosphere. They remain in place for a long time, and the temperature rises steadily.
