Impact of local winds on associated regions:-

1Chinook on leeward side of Rockies causes warming effect → it melts the ice and enables cultivation of crops.
2Sirocco from Sahara desert to the Mediterranean region carries sand dust and causes red-rains in orchards - Thus destroying citrus crops eg olive orchards.
3Foehn on leeward side of Alps has desiccating effect - it melts ice & supports agriculture.
4Mistral in Europe flows down the Rhine valley & intensifies the cold - causes severe weather.
5Bora is similar to Mistral, but more dangerous - it can disrupt day-to-day activities due to extreme cold.
