Researchers found that in summer the weekend rain is more frequent than on weekdays Spanish researchers from the University Barcelona, watching over the years the weather conditions, came to the conclusion that the weather in Western Europe, there are weekly cycles: for example, in the summer at the weekend rain is more frequent than on weekdays. Scientists have observed the weather throughout Spain from 1961 to 2004, and it was found that at different times, the weekly cycles are built differently. In winter, for example, on the contrary – are more sunny weekends than weekdays. Another interesting fact is that Throughout the year, the atmospheric pressure in the middle of the week lower than in the rest of the day. These weather cycles have been linked primarily to environmental pollution: after all, on weekdays, when all businesses operate, the level of pollution above. It is known that the presence of soot in the air can affect the air flow: the dark particles are rapidly heated by the sun and warms the surrounding air, causing it to rise.

In addition, large particles in the air can be the basis for the formation of clouds. Note that prior to the study of Spanish scientists weekly weather cycles were recorded in China, USA and Japan. But why in Europe, these cycles are less pronounced as scientists can not explain … Europeans approve of the introduction of stringent environmental standards in a study commissioned by the organization "Friends of the Earth '(Friends of the Earth), analytical company TNS Opinion concluded that the majority of Europeans approve of the introduction of stringent environmental standards 'Euro 5'.
