Select the correct option from the codes given below:
Answer:
All of them
Notes:
- Mistral – is a strong, cold and usually dry regional wind in France, coming from the north or northwest, which accelerates when it passes through the valleys of the Rhone and the Durance Rivers to the coast of the Mediterranean.
- Sirocco – is a Mediterranean wind that comes from the Sahara and reaches hurricane speeds in North Africa and Southern Europe.
- Chinook – commonly refers to foehn winds in the interior West of North America, where the Canadian Prairies and Great Plains meet various mountain ranges, although the original usage is in reference to wet, warm coastal winds in the Pacific Northwest.
- Harmattan- The Harmattan is a dry and dusty West African trade wind. It blows south from the Sahara into the Gulf of Guinea between the end of November and the middle of March (winter). The temperatures can be as low as 3 degrees Celsius. On its passage over the desert it picks up fine dust particles (between 0.5 and 10 micrometres).
