Important wind terminology

Hurricane factFront:
This is the boundary between two large air masses. It is the meeting point between cold dense air and warm light air. At a front, warm is pushed upwards because of its less density. A front can be very intense or mild, depending on the temperatures of the two air masses that are meeting. Air masses with extreme temperatures will produce a fierce front, whereas air masses with little temperature difference will produce a very mild front.

Hurricane factPrevailing winds:
This is simply a term used for winds that are most frequent in its’ direction and speed over a specific geographic region. Different geographic areas have different prevailing winds because of the factors that shape them.

Hurricane factJet Stream:
This was discovered in the 1940’s (during World War II). Pilots noticed that their flying speeds were significantly reduced when flying against some areas in the upper troposphere. Jet streams can be found in the upper troposphere. They are very strong winds.

Hurricane factBeaufort Wind Force Scale:
In 1805, a British Naval Officer invented this scale to measure wind force. The scale has a reading of 0 up to 12 to classify wind force. —
