1. Blizzards occur in Siberian Plains. A blizzard is a severe snowstorm characterized by strong sustained winds of at least 35 mph (56 km/h) and lasting for a prolonged period of time—typically three hours or more. A ground blizzard is a weather condition where snow is not falling but loose snow on the ground is lifted and blown by strong winds.
2. Chinook winds blow 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.
3. Bora winds blow in Greenland. They are originally defined as a very strong cold wind. It is most common in winter and occurs when cold air crosses the mountains from the east and descends to the coast; thus, it is commonly classified as a gravity (or katabatic) wind. It often reaches speeds of more than 100 km (60 miles) per hour and has been known to knock people down and overturn vehicles.
4. Khamsin blows in Egypt.
