Six typhoons approached within 300 miles of Hongkong during the year, but no destructive winds were experienced. A squall at the rate of 69 m.p.h., however, was recorded during the passage of the typhoon of November 5, at 4.40 p.m. The mean hourly velocity at this time was 56 miles from E by S; the maximum for the year. On June 29 a typhoon entered the coast about 70 miles to the east of Hongkong, having given but little warning of its approach. Fortunately it was of feeble intensity.
The tracks of 14 typhoons and 12 of the more important depressions which occurred in the year 1915 are shown in two plates in the Monthly Meteorological Bulletin for December, 1915.
IV. WEATHER FORECASTS AND STORM WARNINGS.
Daily Weather Report and Map.--A weather map of the Far East and the Daily Weather Report, containing meteorological observations, usually at 6 a.m. and 2 p.m., from about 40 stations in China, Indo-China, Japan and the Philippines, and a daily weather forecast for Hongkong and district, the Formosa Channel, the south coast of China between Hongkong and Hainan, and the south coast of China between Hongkong and Lamocks, were issued as in former years. Copies of the map were exhibited on notice boards at the Hongkong Ferry Pier, the Blake Pier, and the Harbour Office. One copy was sent daily to the Director of the Meteorological Observatory, Macao. The maps were reproduced from the original by the Roneo Litho duplicator. Forty copies of the Daily Weather Report were distributed to various offices, etc., in the Colony, and a copy was sent daily to the Director of the Meteorological Observatory, Macao. Copies were sent every week to Lieutenant-Commander Pradiyat, Royal Siamese Navy.
The Monthly Meteorological Bulletin, which includes the Daily Weather Report, was distributed to the principal observatories and scientific institutions of the world.
Beginning with 1914 January 1, a charge of $10 a year has been made for supplying firms and private individuals with the Daily Weather Report. This has had the desired effect of reducing the distribution list and so accelerating delivery.
Daily Weather Telegrams.-Daily Weather Telegrams from East Coast Ports, Indo-China, the Philippines, and the Japanese Empire have been received with commendable regularity throughout the year. The service from Wladivostock was interrupted from July 20 to the end of the year.
