Q.

Which one of the following is not the example of planetary winds?

A. Monsoon
B. Trade wind
C. Land and sea breezes
D. Chinook
Answer» D. Chinook
Explanation: "Chinook", originally meant a warming wind from the ocean into the interior regions of the Pacific Northwest (the Chinook people lived near the ocean, along the lower Columbia River). A strong Chinook can make snow one foot deep almost vanish in one day. The snow partly melts and partly evaporates in the dry wind. Chinook winds have been observed to raise winter temperature, often from below -20°C (-4°F) to as high as 10-20°C (50- 68°F) for a few hours or days, then temperatures plummet to their base level.
