Shanghai and Manila warnings are broadcast by VPS on a 600 metre spark on receipt, and repeated after an interval of 10 minutes. They are similarly broadcast by ZBW on 355 metres telephony when the Hong Kong Local typhoon signals are displayed.
V.—WEATHER TELEGRAMS, FORECASTS AND STORM WARNINGS.
Daily Weather Telegrams.—In addition to the ordinary 6h. and 14h. observations, which the Cable Companies transmit free of charge, the 11h. and 17h. observations were received at half rates from the following stations:—
Shanghai Gutzlaff Amoy Macao
The 2300 and 0700 G.M.T. observations from Fort Bayard, Phu-lien, Tourane, Cape Padaran and Capt St. James, and the 0300 and 0900 G.M.T. observations from the above, and about 12 other stations in Indo-China, are received from Phu-lien on short wave. This service is very valuable and ensures the early receipt of the observations, and at regular hours, namely at 0115, 0400, 0830 and 1015 G.M.T. It also saves the expense of obtaining the 0300 and 0900 G.M.T. observations by cable.
Other valuable services are the 2200 G.M.T. observations on 23 metres S.W. from Yangtze Ports, and several stations in N.E. China and Korea sent personally by Father Gherzi S.J. of the Zi Ka Wei Observatory, and the 2100 G.M.T. observations from Pelew, Yap, Saipan and Ponape, sent on 1050 metres from the Pelew Observatory at 0200 G.M.T.
The 0600 and 2200 G.M.T. observations from Hoihow are received by wireless telegraphy occasionally.
The Meteorological Authorities at Pratas continue to send, daily, 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 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.
Nothing further has been heard of the projected synoptic weather message from a high power wireless station at Hankow, mentioned in last year's report. Nor have any such messages been received from Naha.
At the request of the Director, National Institute of Meteorology, Nankin, watch was kept at 0010 G.M.T. on 1930 January 22 and 23, for the Tokio synoptic weather message, on 4800 metres, but no signals were heard.
