A tailwind is a wind that blows in the direction of travel of an object, while a headwind blows against the direction of travel. A tailwind increases the object's speed and reduces the time required to reach its destination, while a headwind has the opposite effect.
Ground speed can be determined by the vector sum of the aircraft's true airspeed and the current wind speed and direction; a headwind subtracts from the ground speed, while a tailwind adds to it. Winds at other angles to the heading will have components of either headwind or tailwind as well as a crosswind component.
Due to a tailwind helping to enhance the speed of the athlete in events like certain sprint races (100 and 200 metres), 100/110 metres hurdles, the triple jump and the long jump, there is a limit to how much wind assistance the athlete may compete under if the performance is to establish a record.
For example, a 10 knot wind coming at 45 degrees from either side will have a crosswind component of 10 knots × sin(45°) and a head/tailwind component of 10 knots × cos(45°), both equals to 7.07 knots. Pilots can use a use a crosswind component chart to calculate the headwind component and the crosswind component.
Wind vs. Rockpile. On Mount Washington, high speeds have always been high-profile. On a recent day, the summit wind speed hovered at 68 mph, gusting to 80, with peaks predicted to reach 110 mph ...
Tailwind CSS is an open-source CSS framework. Unlike other frameworks, like Bootstrap , it does not provide a series of predefined classes for elements such as buttons or tables. Instead, it creates a list of "utility" CSS classes that can be used to style each element by mixing and matching.
Sen. Richard Blumenthal, D-Conn., said the mysterious drones spotted in New Jersey over the past few weeks, and most recently in Connecticut, should be “shot down, if necessary."
Elsewhere on the undercard, an all-British heavyweight bout features Johnny Fisher (12-0, 11 KOs) vs. David Allen (23-6-2, 18 KOs). The first fight is scheduled to begin at 11 a.m. Eastern. ___
