HONGKONG OBSERVATORY.
On the relative frequency of Storms in various Seas for different Months in the Year.
The following table exhibits for each month in the year the number of dangerous Atmospheric depressions, expressed in percentage of the average total number, that is yearly recorded in various seas. The similarity between the relative frequency of Typhoons in the China Sea and of Hurricanes in the West Indies is striking. The former have their maximum in September and their minimum in February, while the latter have their maximum in August and their minimum in January. About half the number of both Typhoons and Hurricanes occur in August and September, but the relative frequency of Typhoons in May and November slightly exceeds the relative frequency of Hurricanes. The Cyclones of the Southern Indian Ocean are distributed in a similar manner but have their maximum in February and their minimum in July. But the Cyclones in the Bay of Bengal and the Arabian Sea are quite different and have maxima at the changes of the monsoon in May and October.
