De relatieve LV is hoger dan in de zandduinen ten zuiden en westen van de depressie.
Veel wind staat er soms in maart, dan kun je niet buiten slapen of onder een hele zware kamelendeken. In een tent is ook geen pretje dat houdt me de hele nacht wakker vanwege het klapperen. Nee het liefs geen wind en daarvan zijn er ook genoeg dagen.
Een keer maakten we een paar uur een zandstorm mee dat was gelukkig onderweg maar dan zie je haast niets meer en buiten word je gezandstraald.
De wind, vooral in maart en april, die het warme weer meebrengt wordt Khamsin wind genoemd (gamzien), afgeleid van 50, de periode van 50 dagen waarin hij voor kan komen.
Khams?n , chamsin or hamsin (Arabic: ????? khams?n, derived from the Arabic word for "fifty"), more commonly known in Egypt as khamaseen (Egyptian Arabic: ?????? khamas?n, IPA: [xæmæ?si?n]), is a dry, hot, sandy local wind affecting Egypt; similar winds, blowing in other parts of North Africa, the Arabian Peninsula[citation needed] and the entire Mediterranean basin, have different local names, such as 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 sharkiyya, “easterly”) which blows in winter over much of the Middle East,[1] and simoom.[citation needed]
From the Arabic word for "fifty", these dry, sand-filled windstorms blow sporadically in Egypt over a fifty-day period in spring, hence the name. The term is also used in the southern Levant (Israel, Palestine, Jordan), where the phenomenon takes a partly different form and blows both during spring and autumn.[1]
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 (87 mph; 76 knots), and the humidity in that area drops below 5%. Even in winter, the temperatures rise above 45° C (113° F) 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 II.[citation needed]
In the southern Levant it takes the shape of an opressive weather front with hot temperatures, large quantities of dust impeding visibility, but no strong winds[citation needed] except during the night.[1] In the Book of Exodus of the Hebrew Bible, the ruah kadim or "east wind" is the cause of the parting of the Red Sea(Exodus 14:21).[1]
