The zone-based dust storm warning was replaced by the new blowing dust warning. In addition to the new dust storm warning format, a lesser-impact dust advisory will be issued by the National Weather Service if the criteria for a warning are not met and if travel impacts are still expected. [2]
The Weather Eye was a trade name for a Nash Motors-designed fresh-air system for automobile passenger compartment heating, cooling, and ventilating. [1] The Nash "All-Weather Eye" was the first automobile air conditioning system for the mass market . [ 2 ]
Harmattan, a dry wind that blows from the northeast, bringing dust from the Sahara south toward the Gulf of Guinea. Khamsin (khamaseen in Egypt) and similar winds named Haboob in the Sudan, Aajej in southern Morocco, Ghibli in Libya and Tunisia, Harmattan in the western Maghreb, Sirocco, a south wind from the Sahara and Simoom in the Arabian ...
In some instances these pockets of colder air can descend rapidly, creating a wet or dry microburst which can be extremely hazardous to aviation. Conversely, precipitation evaporating at high altitude can compressionally heat as it falls, and result in a gusty downburst which may substantially and rapidly warm the surface temperature.
Following the passage of a dry cold front, convective instability resulting from cooler air riding over heated ground can maintain the dust storm initiated at the front. In desert areas, dust and sand storms are most commonly caused by either thunderstorm outflows, or by strong pressure gradients which cause an increase in wind velocity over a ...
After the clouds have risen, a rain-cooled layer remains. The cluster shoots a burst of unsaturated air down towards the ground. In doing so, the system loses all of its updraft-related fuel. [6] The raindrops begin to evaporate into dry air, which reinforces the effects of the heat burst (evaporation cools the air, increasing its density).
Carburetor heat (usually abbreviated to 'carb heat') is a system used in automobile and piston-powered light aircraft engines to prevent or clear carburetor icing. It consists of a moveable flap which draws hot air into the engine intake. The air is drawn from the heat stove, a metal plate around the (very hot) exhaust manifold.
The Santa Anas are katabatic winds (Greek for "flowing downhill") arising in higher altitudes and blowing down towards sea level. [7] The National Weather Service defines Santa Ana winds as "a weather condition [in southern California] in which strong, hot, dust-bearing winds descend to the Pacific Coast around Los Angeles from inland desert regions".
