...shells, fossil mollusks, and corals. The main winds prevailing in the area are the bora, a strong northeast wind that blows from the nearby mountains into the sea, and a southeasterly wind named the sirocco that is less troublesome from a navigational point of view. During the six winter months, bora and sirocco alternate, with or without an interval of a few days calm. The tides of the...

Climate, more than relief, is the country's major geographic factor. The amount of precipitation and, above all, its distribution throughout the year, as well as the timing and magnitude of the sirocco—a dry, desiccating wind that emanates seasonally from the Sahara (often with gale force)—constitute the principal elements on which agriculture and many other activities depend.

The Dalmatian coast, Istria, and the islands have a mild Mediterranean climate. In southern Dalmatia, where the sirocco winds (known here as the jugo) bring a moderating influence from Africa, summers are sunny, warm, and dry, and winters are rainy. In the north the winters are drier and colder as a result of the cold northeast wind known as the bora (bura). In the summer the...

...di Calabria the annual mean temperature is 64.7 °F (18.2 °C) and rainfall is 23.5 inches (595 mm); at Palermo, in Sicily, they are 64.4 °F (18 °C) and 38.2 inches (970 mm). The sirocco, a hot, very humid, and oppressive wind, blows frequently from Africa and the Middle East. In Sardinia conditions are more turbulent on the western side, and the island suffers from the cold...

...strong and frequent; the most common are the cool northwesterly (the majjistral), the dry northeasterly (the grigal, or gregale), and the hot humid southeasterly (the xlokk, or sirocco). The relative humidity is consistently high and rarely falls below 40 percent.

...winters and hot, dry summers with no marked intervening seasons. This changes southward to semiarid conditions on the steppes and to desert in the far south. Saharan influences give rise to the sirocco, a seasonal hot, blasting wind from the south that can have a serious drying effect on vegetation.
