China and USA have been hit by an exceptional heat waves without precedent

China has been hit by an exceptional heat wave without precedent. The highest temperature ever was recorded on Sunday 16 July where the thermometer touched 52.2°C in Sanbao, beating the previous National record of +50.7°C.

In other parts of the country, +50°C was reached. This area was the site of an extreme opposite weather event last winter. Jingtao, at -53C, broke the all-time national cold record for China.

Not only China, but also the USA in the grip of a heat wave

The USA is also overwhelmed by an exceptional heat wave, especially the southwestern states, in particular Colorado, Nevada, Arizona and California, where several records were broken on Sunday.

Death Valley reached 53.3C, one step away from its world record of 54.4C. This then is the highest temperature of 2023 globally. While this exceptional heat wave is expected to subside, it will expand into the south-central and southeastern United States, areas where humidity is already driving dangerously high heat rates.

About 63.1 million people, or 19% of the US population are living in areas with dangerous heat levels. Very powerful heatwaves are also sweeping southern Europe, while devastating floods are occurring in the eastern USA, India and South Korea.

A symptom of a climate gone mad due to the climate and environmental crisis. These winds are happening simultaneously in different parts of the planet.
The common feature is that they occur simultaneously. The Rossby waves since April have been affected by a particular situation that has arisen due to the attenuation of La Nina, after 3 years, and the rapid entry of El Nino.

Until June the situation in Europe was different because the anticyclonic blockade was close to Western Europe; this has left the Mediterranean free to attacks by unstable flows and therefore to a more acceptable summer on the warm front.

From the beginning of July there was a rapid variation, with the anticyclone it moved to the Atlantic while at the same time the depressions and promontories developed more along the meridians. When this happens then the possibility of extreme events in the northern hemisphere increases.
