A gale is a strong wind; the word is typically used as a descriptor in nautical contexts. The U.S. National Weather Service defines a gale as sustained surface wind moving at a speed between 34 and 47 knots (63.0 and 87.0 km/h; 17.5 and 24.2 m/s; 39.1 and 54.1 mph). [1] Forecasters typically issue gale warnings when winds of this strength are ...
Moderate gale, near gale 28–33 knots 32–38 mph 50–61 km/h 13.9–17.1 m/s 13–19 ft 4–5.5 m Sea heaps up and white foam from breaking waves begins to be blown in streaks along the direction of the wind; spindrift begins to be seen Whole trees in motion; inconvenience felt when walking against the wind 8 Gale, fresh gale 34–40 knots
Also actiniform. Describing a collection of low-lying, radially structured clouds with distinct shapes (resembling leaves or wheels in satellite imagery), and typically organized in extensive mesoscale fields over marine environments. They are closely related to and sometimes considered a variant of stratocumulus clouds. actinometer A scientific instrument used to measure the heating power of ...
Gale warnings (and gale watches) allow mariners to take precautionary actions to ensure their safety at sea or to seek safe anchorage and ride out the storm on land. Though usually associated with deep low-pressure areas , winds strong enough to catalyze a gale warning can occur in other conditions too, including from anticyclones , or high ...
Gales have caused disruption to air and ferry travel to and from the Isle of Man. EasyJet's services between the island and Liverpool and Gatwick airports faced delays, and the Loganair flight to ...
AAW An acronym for anti-aircraft warfare. aback (of a sail) Filled by the wind on the opposite side to the one normally used to move the vessel forward.On a square-rigged ship, any of the square sails can be braced round to be aback, the purpose of which may be to reduce speed (such as when a ship-of-the-line is keeping station with others), to heave to, or to assist moving the ship's head ...
Within the Beaufort scale, gale-force winds lie between 28 knots (52 km/h) and 55 knots (102 km/h) with preceding adjectives such as moderate, fresh, strong, and whole used to differentiate the wind's strength within the gale category. [22] A storm has winds of 56 knots (104 km/h) to 63 knots (117 km/h). [23]
November gale, the Witch of November, or November Witch, refers to the strong winds that frequently blow across the Great Lakes in autumn. The "witches" are caused by intense low atmospheric pressure over the Great Lakes pulling cold Canadian/Arctic air from the north or northwest and warm Gulf air from the south.
