Year,
Hongkong is situated within the region of the North-East Trade, which farther out in the Pacific reigns supreme all the year round, but under the influence of the Asiatic Continent an annual variation of the Direction of the Wind originates. During the Winter the Direction of the Monsoon coincides with that of the Trade, and we find from Table II, that during seven months of the year (from September to March incl.) the Mean Direction of the Wind is frem East or North of East. During the other five months the Direction is South of East, but the Easterly Direction predominates over the Westerly, except during one month, August, when the Direction is South by West. It is therefore obvious that there does not at any time of the year reign a South-West Monsoon at Hongkong, such as there does in india. But although the power of the North-East Trade is generally superior to its antagonist, the South-West Monsoon, the latter, whenever its pent up energy causes an instable equilibrium, is capable of making a furions resistance, such as is witnessed in the Typhoons, but even these, powerful as they are, must yield to the trade and reccde towards the West except during a few Summer months, when the Mean Direction of the Wind is Southerly, as shown in Table H. Then they follow a track towards the North, till they reach the regions, which lie North of the Trade, where the Direction of the Wind is from South-West.
Table III exhibits the average Force of the Wind (0-12) from different points of the Compass during three years and the mean result of the three years. The superior Force of the East Wind, whose superior Frequency was seen from Table II, is here seen at a glance. The exceptionally small Force of the West North West Wind is due to the sheltering influence of the Continent:-
