The polar wave in southern Brazil has the world’s largest cold anomaly outside the poles

The polar wave in the first half of the week in central and southern Brazil, Uruguay, Argentina and Paraguay brings the world’s largest negative cold anomaly outside the poles. Nowhere on this planet are temperatures below average outside of the polar regions like the central part of South America.

Vast areas of below average temperatures exist in the central plains of the United States, northern Canada and central Russia, but outside Antarctica there is no area on Mondays with below average temperatures like the central part of South America, the effect of which strong Arctic air mass that covers most of the Southern Cone of America.

Snow fell this morning in Santa Catarina, on Planalto Sul Catarinense, and freezing rain fell in São José dos Ausentis (RS) and in Bato Branco, in the southwest of Paraná.

Today’s lows in Argentina were -15.0 °C in MacQuenchau, -11.7 °C in Mallargue, -10.6 °C in Ospaliata, -9.9 °C in La Coyaca, -9 °C in Esquel, and -8.6 °C. Celsius in Perito Moreno. Yesterday, snow fell in places unusual for the phenomenon in the northwest of the province of Buenos Aires and in the south of the province of Santa Fe.

It draws attention in the image of today’s global temperature anomaly as it stands hot Northwestern United States and British Columbia region in Canada. Yesterday Canada recorded the highest temperature in its history with 46 degrees Celsius in British Columbia.

Likewise, the map shows how much colder Antarctica is than average. While in the Arctic the temperature is 0.5°C above average, in Antarctica the temperature is 3.2°C below average. This contributes to the Northern Hemisphere being 0.5°C above average, while the Southern Hemisphere today records less than 0.5°C. The weight of the frozen continent is enormous in the hemisphere anomaly. Worldwide, the anomalous temperature today is 0.2 °C above average.
