The wind gauge at Darwin Airport officially recorded winds of 217 kilometres per hour before being blown away itself. Unofficial estimates suggest that the wind speed actually reached 300 kilometres per hour.
An anemometer measures wind speed. Check your spelling.

The anemometer helped us measure the speed of the wind.
How to Actually Fly a KiteFor many kites, the best way is to set up the kite down wind of where you want to fly and pay out around 150 feet of line while walking to your flying spot. Turn, face your kite, and have someone hold the kite above their head and walk backward until all the slack is taken out of the line. Then, let them throw the kite into the air. Some kites can be launched without assistance, especially those with a delta wing shape. They'll stand up on their wing tips with a gentle pull on the lines; a sharp tug from there will be enough to launch it.
During Cyclone Tracy, the wind speed device recorded up to about 217km/h before the building was blown away.
Wind speed is directly related to pressure differential. Air moves from areas of high pressure to areas of low pressure, creating wind. The stronger the pressure gradient (difference in pressure over distance), the faster the wind will blow.
250km/hr
The bigger affect on wind speed is air pressure.
A series of barometers can be used to predict wind speed and direction. Wind will move from higher pressure areas to lower pressure areas. The higher the pressure differential the higher the wind speed will be.
When the apparent wind speed is doubled, the pressure on the sail is quadrupled. That is because the pressure on the sail (or the side of your house or a billboard sign) is proportional to the square of the speed of the wind. If the wind speed triples, then the pressure goes up by a factor of nine, because three squared is nine.
Isobars, lines on a weather map connecting points of equal atmospheric pressure, can tell you about wind speed by showing areas where pressure gradients are strongest. The closer isobars are together, the stronger the pressure gradient and the faster the wind speed. Wind will flow from high pressure to low pressure areas along isobars.

Air pressure differences between different regions create wind patterns that circulate around a low-pressure center, or cyclone. As air converges towards the center of the low-pressure system, it rises, cools, and condenses, forming clouds and precipitation. The interaction between the Earth's rotation and the wind flow creates a swirling motion in the cyclone.
No. A barometer measures pressure. Wind speed is measured by an anemometer.
The highest sustained wind speed recorded in a tropical cyclone was 190 mph, which was measured in several storms including Hurricane Camille and Typhoon Tip. The highest gust recorded in a tropical cyclone was 253 mph on April 10, 1996 on Barrow Island off the coast of Australia.
By measuring the sustained wind speed. If the wind speed of a tropical cyclone is anywhere in the range of 39 to 73 mph then it is a tropical storm. If the wind speed is 74 mph or greater then it is a hurricane.
