Turbulence - Any irregular or disturbed flow in the atmosphere caused by eddies and vertical air currents. Regions of the atmosphere that are characterized by turbulence will often be found in the vicinity of frontal boundaries. Thunderstorms produce the most severe turbulence due to the intense upward and downward vertical air currents that occur in the vicinity of them.

Blue Jet - An upper-level atmospheric electrical discharge, usually blue or bluish-white in color, that occur high above thunderstorms. Similar to sprites. This phenomenon is believed to connect the tops of thunderstorms with the ionosphere.

Pluie - This is the french word for rain. To say, "it is raining today" one would say, "Il pleut aujourd'hui."

Valley Breeze - A breeze that flows up a mountainside during the day. This upsloping breeze occurs due to the fact that the valley walls warm up faster than the higher terrain in the mountains. This makes the air in the valleys lighter than the air along the higher terrain of the mountains, making the air near the valley buoyant. The result is the upward breeze along the mountainsides during the day.

Hiver - Hiver is the French word for winter.

Willy-Willy - A term most commonly used in Australia referring to a dust devil. Dust devils are small, rapidly rotating columns of wind that are made visible by dust or dirt that get sucked into them. They are most commonly seen in the afternoon on hot, dry days.

Mountain Breeze - A wind pattern that develops during the night due to differential cooling on the mountain compared to nearby valleys. The mountain cools faster than the valleys in the evening. This cool, dense air blows down the mountainsides into the valleys. The opposite occurs during the day, which produces an upslope wind known as the valley breeze.
