Since September 29 the 0600 and 2200 G.M.T. observations from Hoihow have been received by wireless telegraphy occasionally.
The Meteorological Authorities at Pratas continue to send, with commendable regularity and promptitude, their 6h., 11h., 14h., and 17h. observations and the 6h. observations from some Philippine stations. They also send hourly observations during the passage of a typhoon.
Though the number of observations received for constructing the daily weather maps has increased of late years, owing to the advent of wireless telegraphy, far more observations are still required before even approximately accurate maps can be drawn, showing kinks in the isobars, lines of discontinuity, cold fronts, warm fronts etc. At present the observations of temperature are so few that no attempt is made to draw isotherms on the weather maps.
Proposals for the establishment of additional meteorological reporting stations are to be submitted to the Pan-Pacific Science Conference which will take place in Batavia next May, and to the Conference of British meteorologists, which is to take place in London next August.
Monsieur Jean Coffin, of the French Meteorological Service, while on a tour of the Far East in connection with an improved service of wireless meteorological broadcasts, visited the Observatory on January 31 and March 3. He informed me that the Tokio Observatory proposed to send the 6 a.m. observations from 20 stations in the Japanese Empire daily to the Naha Wireless Station, which would broadcast them on short wave, using the Hong Kong 6-letter telegraphic Code. He also stated that observations might be expected from a high power station in Hankow at an early date; no details of the above schemes are to hand.
Extra Weather Telegrams. The following stations send extra weather telegrams at half rates during typhoons, on receipt of certain code words from Hong Kong:-Amoy, Canton, Macao, Phu-lien, Sharp Peak and Taihoku. The Director of the Philippines Weather Bureau also sends extra telegrams, at his discretion, from Aparri or some other station nearer the typhoon centre. The 9 p.m. observations from Swatow, kindly sanctioned by the Chinese Telegraph Administration, were occasionally received; but usually on the next or following day. The Director of the Taihoku Observatory sends extra weather telegrams from the two stations in Formosa nearest to the centre during the passage of a typhoon.
