Question

what do you mean by khasmin

Answer 1

Khamsīn , chamsin or hamsin (Arabic: خمسين‎ khamsīn, "fifty"), more commonly known in Egypt as khamaseen (Egyptian Arabic: خماسين‎ khamasīn, IPA: [xæmæˈsiːn]), is a dry, hot, sandy local wind, blowing from the south, in North Africa and the Arabian Peninsula. Similar winds in the area are sirocco and simoom. From the Arabic word for "fifty", throughout the Levant, these dry, sand-filled windstorms often blow sporadically over a fifty-day period in Spring, hence the name.

Dust storm over Libya (NASA/EOS)

When the storm passes over an area, lasting for several hours, it carries great quantities of sand and dust from the deserts, with a speed up to 140 kilometers per hour, and the humidity in that area drops below 5%. Even in winter, the temperatures rise above 45°C due to the storm. The sand storms are reported to have seriously impeded both Napoleon's military campaigns in Egypt as well as Allied-German fighting in North Africa in World War
