The hot front coming from Africa with warm and dry tropical air also brings with it fine desert sand from the Sahara that is scattered in the air. According to experts, the phenomenon of “bloody rain” occurs when reddish grains of sand are mixed with raindrops, experts explain, writes the Telegraph.
According to experts, the conditions for such precipitation in Bulgaria are on Thursday and Friday. The weather in Sofia on Friday and Saturday is expected to cool for a while, as temperatures could drop to 26 degrees, but then the temperature will rise again quickly. However, by August 12-13 in Bulgaria temperatures will be above normal, which will be very high.
Despite the infernal heat, it is not expected that the national record of 45 degrees, measured in Plovdiv in 2000, will improve, says climatologist Professor Georgy Rachev from Sofia University “St. Clement of Ohrid “. In this series of days with abnormal and record temperatures, it is good that the air is relatively dry and the relative humidity at noon is below 30%. “If the humidity was twice as high – 60%, as usual, there would be no life on the street and it would be very difficult to tolerate the heat,” said the professor.
The summer of 2021 is expected to be warmer than last year. However, he noted that this is not a unique phenomenon and is not the first time in the climate of Bulgaria. “There is global warming, but we do not need to go back to grandparents. In 2007 the summer was very hot and long, as well as in 2012, when we experienced the warmest and longest summer in the modern history of Bulgaria,” said a climatologist from Sofia University. .
