Mistral (wind) prehistoric site called Terra Amata, at the foot of Mount Boron in Nice, showed that in about 40,000 B.C. the inhabitants had built a low wall of rocks and beach stones to the northwest of their fireplace to protect their fire from the power of the mistral. The "mas" (farmhouse) traditionally faces south, with its back to the mistral. The bell towers of villages in Provence are often open iron frameworks, which allow the wind to pass through. The traditional Provençal Nativity scene usually includes a figure of a shepherd holding his hat, with his cloak blowing in the mistral.
Sirocco the low propels the mixed air across the southern coasts of Europe. The sirocco causes dusty dry conditions along the northern coast of Africa, storms in the Mediterranean Sea, and cool wet weather in Europe. The sirocco's duration may be as short as half a day or may last several days. While passing over the Mediterranean Sea, the sirocco picks up moisture; this results in rainfall in the southern part of Italy, known locally as "blood rain" due to the red sand mixed with the falling rain. Many people attribute health problems to the sirocco, either because of the heat
