Convective overshoot : ウィキペディア英語版 | Convective overshoot
Convective overshoot is a phenomenon of convection carrying material beyond an unstable region of the atmosphere into a stratified, stable region. Overshoot is caused by the momentum of the convecting material, which carries the material beyond the unstable region. == Deep, moist convection in Earth's atmosphere == : ''Main article: Overshooting top'' One example is thermal columns extending above the top of the equilibrium level (EL) in thunderstorms: unstable air rising from (or near) the surface normally stops rising at the EL (near the tropopause) and spreads out as an anvil cloud; but in the event of a strong updraft, unstable air is carried past the EL as an ''overshooting top'' or ''dome''. A parcel of air will stop ascending at the maximum parcel level (MPL). This overshoot is responsible for most of the turbulence experienced in the cruise phase of commercial air flights.
