WHAT ARE THE FEATURES OF CHINOOK?
Chinook winds often called chinooks, 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 of the United States of America.
One of its most striking features is the Chinook arch, which is a band of stationary stratus clouds caused by air rippling over the mountains due to orographic lifting. To those unfamiliar with it, the Chinook arch may look like a threatening storm cloud at times. However, they rarely produce rain or snow. They can also create stunning sunrises and sunsets.

The stunning colours seen in the Chinook arch are quite common. Typically, the colours will change throughout the day, starting with yellow, orange, red and pink shades in the morning as the sun comes up, grey shades at midday changing to pink/red colours, and then orange/yellow hues just before the sun sets.
