If the "spread" between the peak gust and lowest lull in the wind speed is high, many canopy pilots experience a bumpy ride. Typically, jumpers consider anything over about a 10 mile an hour difference between the average wind speed and the peak gust to be high enough to cause trouble. ... 2 Replies to "What's Your Wind Limit?"

Typically, jumpers consider anything over about a 10 mile an hour difference between the average wind speed and the peak gust to be high enough to cause trouble. So, if the winds are 10 gusting to 21, many jumpers will choose to sit down because the air feels "dirty" or "bumpy".

Because low wind speeds are the most common, it is essential that waterpumping windmills work in low wind speeds. This design is not a product of accident! It is the result of two years of meticulous scientific study where more than 2000 tests were conducted on 65 different designs of wind wheels and many variations of these designs.

The Current Wind map shows the current wind speed and direction for the most recent hour. Wind direction is determined by the direction from which it originates. For example, a northerly wind blows from the north to the south. Wind is the flow of air that occurs as it is heated by the sun and thus rises.

Wind speed generally increases with height. T Backward stability.. Backward stability can be a problem when the wind is from the front and the boom is high. T Wind from behind a crane.. Wind coming from the rear of the crane can cause the load to be blown away from the crane, increasing the radius and decreasing the crane capacity.
