Shergi (from Arabic. الشرق (sharq - east)) is the east or south-east local wind in Morocco blowing from the Sahara . Extremely dry, hot and dusty in nature gives it a resemblance to the sirocco wind prevalent in the Mediterranean [1] . From the point of view of weather forecasters, the wool is unique due to its eastern direction and origin, different from the Sirocco [2] . The latter is largely due to interaction with the ridge of the Atlas Mountains , in connection with which the scrubs are classified as foehns [3] .
Most often, the wool blows in July and August [2] . In the period of shergas, which can last several days, the temperature on the Atlantic coast of Morocco rises by 10 or more degrees, often exceeding 40 degrees. Sometimes a dusty wind mixes with raindrops, polluting everything in its path. Clubs of dust and fine sand rush into the Atlantic Ocean , reaching the Canary Islands .
