The generation mechanisms of two turbulence events that occurred near the Korean Peninsula and led to aircraft accidents were investigated using high-resolution numerical simulations with the Weather Research and Forecasting (WRF) model. The first case occurred on 12 January 2020 at 0417 UTC: an aircraft that departed from Kitakyushu Airport, Japan, en-route to Incheon Airport, encountered moderate intensity turbulence in clear sky at an altitude of 25,000 ft (approximately 375 hPa) over Fukuoka. Turbulence was observed beneath the core of a jet stream, where wind speeds exceeded 90 m s<sup>-1</sup> over South Korea and strong horizontal wind shear and deformation appeared at the location of turbulence encounter. A developed upper-level frontal system induced strong vertical wind shear and tropopause folding down to approximately 480 hPa. Despite the relatively stable stratification, the strong vertical wind shear caused the Richardson number to decrease, leading to the generation of turbulence through the Kelvin-Helmholtz instability. The second case was 27 May 2021 at 2253 UTC: an aircraft that departed from Gimpo Airport en-route to Jeju Airport encountered severe intensity turbulence at an altitude of 17,000 ft (approximately 515 hPa) over Yesan, South Korea. A localized front developed north of the turbulence encountered location and propagated southeastward, during which it generated gravity waves with a horizontal wavelength of about 10 km. The localized front induced strong vertical wind shear by the thermal wind relationship, and the propagation of the gravity waves enhanced the Kelvin-Helmholtz instability, resulting in turbulence.
