Have you ever done some approaches onto 07R with winds which have a southerly component?
If not, then a quote from the Jepp HK Airport Briefing plate might answer your question.
1.7.2.2. EASTERLY THROUGH SOUTHWESTERLY WINDS
When prevailing winds are from the East through Southwest and with a speed in
excess of 15 KT, significant windshear and moderate turbulence can be expected on the approaches to or on departure from both RWYs. Larger magnitude of windshear and turbulence is possible when the wind speed is in excess of 30 KT. Because of the closeness to the hills of Lantau, the windshear and turbulence are more significant over the southern RWY (RWY 07R/25L).
