What causes gale-force winds?
A gale force wind (or gale) is a strong, persistent wind with a minimum speed of 50 km/h (31 mph) and a maximum speed of 102 km/h (63 mph), which are typically associated with coastal regions. … Typically, these strong winds are caused by a rapid drop in air pressure (indicated by a steep pressure gradient.)
What does gale mean in weather?
gale, wind that is stronger than a breeze; specifically a wind of 28–55 knots (50–102 km per hour) corresponding to force numbers 7 to 10 on the Beaufort scale. As issued by weather service forecasters, gale warnings occur when forecasted winds range from 34 to 47 knots (63 to 87 km per hour). gale.

Who invented the Beaufort scale?
Francis BeaufortBeaufort scale / Inventor
One of the first scales to estimate wind speeds and the effects was created by Britain’s Admiral Sir Francis Beaufort (1774-1857). He developed the scale in 1805 to help sailors estimate the winds via visual observations.
What Gale Force is a hurricane?
Through 1986, the National Hurricane Center used the term gale to refer to winds of tropical force for coastal areas, between 33 knots (61 km/h; 17 m/s; 38 mph) and 63 knots (117 km/h; 72 mph; 32 m/s). A common alternative definition of the maximum is 55 knots (102 km/h; 63 mph; 28 m/s).
What Is a Force 11 gale?

Why do the big trees fall down during Cyclone?
Falling of the big trees is due the impact of strong winds on the tree and flow separation and turbulence formation due high speed flow around a tree. After the initiation there is a shift in the Center of Gravity and rigidity of the tree trunk brings the tree down.
What happened to the Andrea Gail in the movie?
In the movie, the Andrea Gail was swamped by a massive wave in the middle of the storm. In truth, no one is sure what happened to the ship or its crew. “I think the book was true, well researched, and well written,” said Maryanne Shatford, sister of missing crewman Bob Shatford. “It was the movie that was too Hollywood.

Where did the Andrea Gail set its course?
The Andrea Gail set its course east toward Flemish Cap, another fishing ground where Tyne hoped they’d make a nice haul. It was especially important for the ship to fill its hold quickly, since the ice machine had broken down, meaning that anything they did catch would be spoiled by the time they got back to port if they stayed at sea for too long.
