6. CONCLUDING REMARKS
Preliminary analyses of limited available wind data in the Deep Bay
area indicate that the prevailing flow in the area is different from that of
other locations in Hong Kong. The prevailing flow at Tsim Bei Tsui suggests more
frequent occasions suitable for aircraft landing or take-off operations towards
the southwest than at Chek Lap Kok. However, the quantity and quality of
available wind data are not adequate to support firm conclusions.
Visibility conditions over Deep Bay are likely to be similar to those
near Chek Lap Kok. There are difficulties in the interpretation of available
cloud base data. The observations made at Ping Shan are probably not applicable
to Deep Bay.
Reports made during the limited number of RHKAAF flights so far suggest
that turbulence and wind shear are likely to be less severe at Deep Bay than at
Chek Lap Kok. However, Kai Kung Leng and the nearby hills may give rise to some
significant turbulence or wind shear in the approach towards a runway in Deep Bay
when winds are strong easterly.
The construction of an airport in Deep Bay will change the tidal
characteristics significantly. This will require a thorough study in view of
its possible impact on the civil engineering design and the ecology of the
coastline around Deep Bay.
