Khamsin
Khamsin, chamsin or hamsin (Arabic: خمسين ḫamsīn, meaning "fifty"), more commonly known in Egypt, Israel and Palestine as khamaseen (Egyptian Arabic: خماسين ḫamāsīn, IPA: [xɑmæˈsiːn] ), is a dry, hot, sandy local wind affecting Egypt and the Levant; similar winds, blowing in other parts of North Africa, the Arabian Peninsula and the entire Mediterranean basin, have different local names, such as bad-i-sad-o-bist roz in Iran and Afghanistan, haboob in the Sudan, aajej in southern Morocco, ghibli in Tunis, harmattan in the western Maghreb, africo in Italy, sirocco (derived from the Arabic šarqiyya, "eastern") which blows in winter over much of the Middle East, and simoom. From the Arabic word for "fifty", these dry, sand-filled windstorms blow sporadically in Egypt typically after fifty days from the start of spring, hence the name.
