Study of a possible wake vortex encounter of an aircraft over the Arabian Sea

[摘要] A Jet airways aircraft encountered severe turbulence over the Arabian sea. We have performed high-resolution numerical simulations of the weather conditions at the time of the incident to ascertain the possible cause of the incident: atmospheric clear-air turbulence or a wake vortex encounter. Our analysis of the turbulence indices and parameters related to vortex propagation/decay at the flight altitude, suggests that wake-vortex encounter was the more likely cause of the incident.
