Most winds travel horizontally, as does most wind shear, but under certain conditions, including thunderstorms and strong frontal systems, wind shear will travel in a vertical direction. Microburst wind shear... can cause an aircraft to lose lift and crash, especially during takeoff or landing, when the slower speeds and closeness to the ground make altitude correction more difficult. Since 1996 all U. S. airliners have been required to be equipped with instruments that provide the pilot with advance warning of wind shear.  5, record 2, English, - wind%20shear

wind shear. ... Shear usually refers to vertical wind shear (i.e., the change in wind with height) but the term also is used in Doppler radar meteorology to describe changes in radial velocity over short horizontal distances.

Downburst with a small lateral extent, about 1 to 4 km, and lasting only a short time.  4, record 3, English, - microburst

Record number: 3, Textual support number: 1 CONT

The microburst has a strong downflow descending very close to the ground. The ground turns the vertical winds into horizontal winds. The maximum horizontal extent of a microburst is on the order of 4 km in diameter but can be less than 1 km in diameter. Despite this small scale, an intense microburst can induce horizontal wind radials as high as 160 km/h.  5, record 3, English, - microburst

To recover from the microburst, the crew apply maximum power and pitch up toward an angle that can attain 15 degrees. The inertial acceleration(acceleration in reference to the ground, as opposed to acceleration within the airmass) experienced by the pilots, combined with the unstable attitude of the aircraft may cause a dangerous illusion. The pilots may believe that the aircraft has reached a very high excess energy and thus, try to pitch down or reduce the engine power. In reality, the aircraft performance is still low as it penetrates the energy-reducing downdraft and tailwind components of the microburst.  2, record 4, English, - inertial%20acceleration

Microbursts result as a strong downflow bursts from a parent cloud and strike the Earth’s surface at an angle (usually) off-the-vertical. The air striking the Earth flows out from the centre (called an "outflow") at speeds which depend on the downflow speed and striking angle. As the outflowing air undercuts the surface air, a vertical roll begins to develop that eventually encircles the downflow centre as a horizontal vortex ring.  1, record 5, English, - outflow
