This is a picture of a "Sand Storm" or sometimes referred to as a "Dust Storm." These storms are caused by intense winds blowing along the desert in close proximity to the ground. When the wall of warm air hits a cold front it causes a convection current that creates an effect similar to a tornado drawing up the dust and sand into the atmosphere. April is often referred to as the "Sand Storm" month.
