Naturspektakel - photos sent user to us a Naturspektakel of the special class could one Saturday morning in west Austria observe. Sahara sand colored the sky orange. Many in addition photos sent user to us. Stormy south wind responsible for the orange sky color is a stormy south wind, which comes directly from North Africa. The foehn to country brings here in consequence unites Sahara sand with itself. This weather-technical phenomenon could weden in this strength in Vorarlberg never seen, says Arnold Tschofen of the weather station in Bregenz. So an extreme sky discoloration does not occur on the average every 15 years, dangerously is the Sahara dust.
This is, curiously, my motto in life.
This is similar to a phenomenon which periodically occurs in southern Spain and is referred to as the 'Levante'. I'm not a meteorologist, but understood it to be the result of strong wind (and sand) blowing up from North Africa into the Iberian Peninsula. The air would get very heavy and discolored for a few days whenever this occurred.
