To the south of the Hong Kong International Airport (HKIA) lies the mountainous Lantau Island (Figure 1) with peaks rising to about 1000 m AMSL and valleys as low as 300 m. Sometimes, the air climbing over this hilly terrain could be disrupted to form mountain waves, gap outflow, eddies, etc. over the flight paths of HKIA, causing windshear. Most of the windshear episodes are related to airflow disturbances by the complex terrain near HKIA.
