Abstract
COL. E. GOLD points out that, in the article entitled “Climate of Hong-Kong”(NATURE, Jan. 21, p. 104) the statement “much of it [mist and fog] is due to dynamical cooling of advancing damp southerly winds” requires amplification. Damp air moving from the south and rising to the higher levels of Hong-Kong about 1,500 ft. above the level of the Observatory and 1,600 ft. above sea-level is cooled by expansion as it rises and so causes much of the fog and mist at these higher levels. The fog and mist at sea-level, when it occurs with a warm southerly current of air, is due to the cooling of this current by the surface of the sea—or the surface of the land.
