The figures in the above table include the number of and number of hours the Local signals were hoisted in each hoisted.
47. The warning signal indicates that a signal indicates that a depression or typhoon exists which may possibly affect the locality. Signals 2-8 indicate that a gale is expected at Hong Kong. Signal No. 9 indicates that gale is expected to increase. Signal No. 10, accompanied by three bombs fired at intervals of 10 seconds, indicates that wind of typhoon force is anticipated.
VI.-METEOROLOGICAL OBSERVATIONS FROM SHIPS, TREATY PORTS, ETC.
48. Logs received. In addition to meteorological registers kept at about 40 stations in China, meteorological logs were received from 134 ships operating in the Far East. These logs, representing 7,843 days observations have been utilised for amplifying the weather maps and verifying typhoon tracks. The corresponding figures for the 1930 were 192 and 10,273.
49. Comparison of Barometers.-The corrections to ships' barometers are usually obtained by comparing their readings while at Hong Kong with those of the Observatory Standard. Occasionally ship captains bring their barometers to the Observatory to be compared with the Standard.
