Natural hazards come in the form of hot, dry, dust-laden sirocco (known in Libya as the ''gibli''). This is a southern wind blowing from one to four days in spring and autumn. There are also dust storms and sandstorms. Oases can also be found scattered throughout Libya, the most important of which are Ghadames and Kufra. Libya is one of the sunniest and driest countries in the world due to prevailing presence of desert environment.
