IMPORTANT ROLE OF VOLUNTARY WEATHER OBSERVING SHIPS
******
HONG KONG IS NOW KEEPING A CREDITABLE FLEET OF 44 VOLUNTARY WEATHER OBSERVING SHIPS WHICH COLLECT INFORMATION FOR THE ROYAL OBSERVATORY THROUGHOUT THEIR VOYAGES.`
WEATHER OBSERVATIONS ARE DESPATCHED BY RADIO AT FIXED INTERVALS OF EVERY SIX HOURS DAILY TO THE CENTRAL FORECASTING OFFICE OF THE ROYAL OBSERVATORY,
INFORMATION RECEIVED FROM VARIOUS OBSERVING SHIPS WILL BE GATHERED, VERIFIED AND USED FOR PREPARING WEATHER BULLETINS AND FORECASTS FOR ALL SHIPS IN THE WEST PACIFIC AND CHINA SEAS.
+REGULAR WEATHER REPORTS FROM SHIPS AT SEA ARE THE MOST IMPORTANT SOURCE OF INFORMATION WHICH FORECASTERS BASE UPON IN FORMULATING FORECASTS,+ SAID MR. CHU WING-KI, SCIENTIFIC OFFICER IN CHARGE OF THE ROYAL OBSERVATORY'S MARINE METEOROLOGICAL SECTION. +THEY ARE MORE RELIABLE AND INEXPENSIVE.+
+METEOROLOGICAL SATELLITES ARE HELPFUL IN OBTAINING CERTAIN WEATHER INFORMATIONS,+ HE SAID, +BUT THEY CANNOT REPLACE SHIPS' REPORTS.+
+FOR EXAMPLE,+ HE EXPLAINED, +SEA SURFACE PRESSURE, WIND SPEEDS AND SEA WAVES CANNOT BE INFERRED FROM SATELLITE PICTURES WITH ACCEPTABLE PRECISION.+
MASTERS OF SHIPS BASED IN HONG KONG ARE OFTEN CONTACTED BY THE SECTION'S PORT METEOROLOGICAL OFFICER TO VOLUNTEER FOR THIS WEATHER OBSERVING SERVICE.
ONCE IT IS AGREED, METEOROLOGICAL INSTRUMENTS SUCH AS BAROMETER, THERMOMETER AND BAROGRAPH AS WELL AS LOG
BOOKS AND RADIO FORMS WILL BE PROVIDED. THE SHIP'S OFFICERS WILL ALSO BE BRIEFED ON THEIR USES.
THE PORT METEOROLOGICAL OFFICER ALSO KEEPS REGULAR CHECKS ON WEATHER OBSERVING INSTRUMENTS OF VOLUNTARY SHIPS WHENEVER THEY COME INTO PORT.
WHEN A SHIP SETS OUT TO SEA, MR. CHU EXPLAINED, OFFICERS ON BOARD WILL MAKE REGULAR WEATHER OBSERVATIONS, RECORD THEM IN THE LOG BOOK AND AT THE SAME TIME RADIO REPORTS TO WEATHER COLLECTING CENTRES.
