The instruments used to measure wind are known as anemometers and can record wind speed, direction and the strength of gusts. The normal unit of wind speed is
the knot
(nautical mile per hour = 0.51 m sec-1 = 1.15 mph).
What is wind speed and how is it measured?
The speed of that wind can be measured using
a tool called an anemometer
. An anemometer looks like a weather vane, but instead of measuring which direction the wind is blowing with pointers, it has four cups so that it can more accurately measure wind speed.

down tree limbs
and potentially cause power outages. … – at 55 to 63 mph, entire trees can be uprooted and considerable structural damage can occur. – above 64 mph, expect widespread structural damage.
Can a plane fly in 30 mph winds?
With this in mind, horizontal winds (also known as “crosswinds”) in excess of 30-35 kts (about 34-40 mph)
are generally prohibitive of take-off and landing
. … If crosswinds are strong while the plane is at the gate, air traffic controllers maybe simply delay departure, as they would during heavy snow.

What is a strong wind blowing called?
Short bursts of high speed wind are termed gusts. Strong winds of intermediate duration (around one minute) are termed
squalls
. Long-duration winds have various names associated with their average strength, such as breeze, gale, storm, and hurricane.
