If the airmass is unstable, air which is pushed upward by some force will continue upward. An unstable airmass usually contains relatively warm(usually moist) air near the earth's surface and relatively cold(usually dry) air in the mid and upper levels of the atmosphere.  4, record 2, English, - unstable%20air%20mass

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 3, English, - inertial%20acceleration
