It will be seen that the number of messages received has increased, averaging 18 ships per day in 1922. This represents only 12% of the average number of ships within call of Cape d'Aguilar, however. It is to be hoped that the time is not far distant when every ship within call will send observations by radio telegraphy as a matter of routine, in accordance with the Notice to Mariners on the subject.
Results of Weather Forecasts.-The results of the comparison of the daily weather forecasts with the weather subsequently experienced are given below, with the results of the previous five years :-
Year Complete Success Partial Success Partial Failure Total Failure % 1917 67 29 1918 71 26 3 1919 71 27 + MON 1920 64 30 1921 65 30 1922 67 30 3No forecasts were issued on January 1, February 12, March 4, July 7, 8, 9 and August 6, owing to lack of telegraphic information.
The forecast comprises wind direction, wind force, and weather. Complete success means correct in three elements. Partial success means correct in only two elements. Partial failure means correct in only one element. Total failure means correct in no element.
The method of analysis is described in the 1918 Report.
Storm Warnings.-At the request of the Chamber of Commerce the Hongkong Government adopted the China Seas Storm Signal Code from 1920, June 1, in place of the Hongkong Non-Local Code introduced in 1917. The signals are displayed on Kowloon Signal Hill.
The following Ports are warned by a telegraphic adaptation of the code:-Sharp Peak, Swatow, Amoy, Santuao, Macao, Canton, Wuchow, Phulien, Taihoku, Manila, Labuan, and Singapore. 124 storm warnings were sent in 1922 and 141 were received from Manila. 26 were received from Phulien, via Quang Chau Wan Radio Station.
The storm warning service to Pakhoi and Hoihow has been discontinued, as the warnings never arrive in time to be of any use.
