Storm Warnings.-In view of the urgent need of an improved service of storm warnings, new Local and Non-Local Storm Signal Codes were introduced on July 1.
The Non-Local code supersedes the "China Coast" code and the "Hongkong Telegraphic Code". The signals are made by means of ten symbols representing the ten numerals. They are displayed at the yard arms of the Storm Signal mast on Signal Hill, Kowloon.
The following information is given:
(a) Position of centre, in degrees of latitude and longitude; by 4 symbols at one yard arm.
(b) Direction and velocity of motion, and the time; by 3 symbols at the other yard arm.
Monsoon Gales are signalled by 3 symbols at one yard arm. The top symbol indicates the region threatened, the middle symbol the direction from which the gale is expected, and the bottom symbol the time at which gale conditions were first indicated.
Warnings in accordance with this code are telegraphed to the following Ports:--Sharp Peak and Santuao (Foochow), Taihoku (Formosa), Swatow, Macao, Canton, Pakhoi, Hoihow, Phulien, Manila, Labuan, and Singapore.
The new Local code of Storm Signals is the complement of the Non-Local code. The latter gives the position of the typhoon and its direction and velocity of motion, while the former indicates the probable direction and force of the wind likely to be experienced at Hongkong.
To a certain extent Signal 1 of the new code corresponds to the red, and signals 2 to 5 to the black signals of the old code. Signal 7 is the same as the urgent signal of the old code, and Signal 6 is new.
There are four main signals:
No. 1 A "Stand By" signal.
Nos. 2-5 A warning that a gale may be expected from one of four directions.
No. 6 A warning that the gale is expected to increase. No. 7 A warning that a gale of typhoon force may be expected.
Distinctive day symbols are assigned to each of the four main signals; the four directions of signals 2 to 5 being represented respectively by a cone point upwards for North, a cone point downwards for South, a ball for East, and a drum for West.
The night signals, which consist of three vertical electric lights, were designed on the following principles:
(1) That red shall indicate the greatest danger and white the least.
(2) That of the two upper lights white shall represent west and green east.
