How to calculate wind speed?
Subtract the GS vector from the TAS vector for each vertical and horizontal value and the wind speed is calculated using pythagoream theorem A^2 + B^2 = C^2 where C is the wind speed. The wind direction is calculated using the arctan function and checking if the wind is a headwind of a tailwind WS = Wind Speed
What is considered a medium wind speed?
Medium Winds (8-24 mph) Most kites don’t need a lot of wind, but they fly best when there is a gentle to moderate breeze. Standard kites such as the Delta and Diamond kites fly best with a wind speed of around 8-24 mph.
What is wind speed usually given in?
Wind speed is typically reported in miles per hour, knots, or meters per second. One mile per hour is equal to 0.45 meters per second, and 0.87 knots. Wind direction is typically reported in degrees, and describes the direction from which the wind emanates. A direction of 0 degrees is due North on a compass, and 180 degrees is due South.
What is the meaning of wind speed?
Wind speed describes how fast the air is moving past a certain point. This may be an averaged over a given unit of time, such as miles per hour, or an instantaneous speed, which is reported as a peak wind speed, wind gust or squall.

Can you drive in 80 mph winds?
Consider staying put 30mph and 45mph winds can be strong enough to make driving dangerous, never mind when a storm's coming in and winds can reach in excess of 80mph. If the winds are strong, consider avoiding travel altogether, especially if your journey involves long distances, motorways or an abundance of bridges.
Can I walk in 70 mph winds?
Attempting to walk in 60-70mph winds is dangerous, and there is a high risk of being blown over and suffering injury. Stay away from difficult underfoot conditions or exposed edges and get off the hill as soon as possible.
Can you walk in 30 mph winds?
Windy Facts Walking in a 30 mph wind can be tricky, at 40 mph you could be blown off balance and at 60 mph it is almost impossible to walk. The wind speed given by the BBC or local radio station will be at sea level.
How do you read wind speed?
A single short line (half line) or "feather" represents 5 knots (5.75 mph) of wind speed. A single long line (full line) or "feather" represents 10 knots (11.50 mph). A fully blackened triangle, "pennant," or "flag" on the barb represents 50 knots (57.50 mph) of wind speed.
What wind speed causes trees to fall?
During storms, there is a critical wind speed, of around 42 m/s (90 mph), at which almost all tree trunks break – irrespective of their size or species – according to a new study done by researchers in France.

What wind speed can flip a car?
The study showed that head winds with wind speeds of up to 115 miles per hour do not tip over vehicles, however crossing the 115 miles per hour mark, the results are much different. Touching 180 miles per hour, any stationary or in motion vehicle has an increased chance of tipping over.
