Result
Your answer: —  Â·  Correct: A
Explanation

Sirocco is a hot, dry, and dusty local wind that originates in the Sahara or Arabian deserts [2]. It is a Mediterranean wind that arises from warm, dry tropical air masses pulled northward by low-pressure cells moving eastward across the Mediterranean Sea [1]. As it blows from the desert interiors toward Southern Europe, it causes scorching heat and dusty conditions along the northern coast of Africa, often withering crops [2]. While it is initially dry, it absorbs moisture as it crosses the Mediterranean Sea, eventually bringing cool, wet weather or storms to parts of Europe [1]. The term is derived from the Italian 'scirocco' and the Arabic 'sharq', meaning east. It is classified as a local wind because its effects are confined to specific geographical regions and the lower levels of the troposphere.
