HH,
I thought about that too, but looking at the runway orientation, I suspect they get healthy onshore crosswinds.
As HH graciously said, dook has control.
PS I recently completed the Melbourne to Hong Kong leg of the Round-the-World virtual race on sailonline.org. Quite a few PPRuNers participate - my vessel is Miss Saigon. When transiting the chain of islands in the Luzon Strait, I wondered where the boundary between the Philippines and Taiwan was. That's how I discovered Lanyu/Orchid island.
