Irregular, chaotic air movement that causes sudden jolts for aircraft. Common near thunderstorms, mountains and jet streams.
basicWhat is Turbulence?
Turbulence comes in several forms: convective (from thunderstorm updrafts/downdrafts — the most dangerous), clear-air (CAT, near jet streams at cruise altitude), mechanical (wind flowing over mountains or buildings) and wake (behind large aircraft). Southeast Asia has high turbulence risk during the monsoon season due to intense convective activity. The Inter-Tropical Convergence Zone is a persistent zone of turbulence for trans-equatorial flights.
