What dangerous aerodynamic sequence does an aircraft encounter when flying through a convective microburst on short final approach?

1. A steady, uniform tailwind that gently accelerates the aircraft to touchdown
2. A complete loss of engine oil pressure caused by low atmospheric humidity
3. An initial strong performance-increasing headwind (causing a pitch-up and climb), followed immediately by intense downdrafts and a severe performance-decreasing tailwind, causing rapid loss of airspeed and altitude
4. An immediate increase in aircraft gross weight due to barometric condensation
