PREDICTING TROPICAL CYCLONE MOVEMENTS BY COMPUTER

X X X X

STARTING THIS SUMMER, OBJECTIVE FORECASTS OF TROPICAL CYCLONE TRACKS WILL BE PREPARED BY THE COMPUTER DIVISION OF THE ROYAL OBSERVATORY AND DISSEMINATED TO COUNTRIES IN THE SOUTHEAST ASIA REGION THROUGH INTERNATIONAL TELE- COMMUNICATION CIRCUITS FOR THEIR OPERATIONAL USE.

THIS ARRANGEMENT IS THE RESULT OF A REQUEST MADE BY MEMBER COUNTRIES OF THE TYPHOON COMMITTEE DURING A PREVIOUS. SESSION.

OBJECTIVE TECHNIQUES FOR PREDICTING TROPICAL CYCLONE MOVEMENT HAVE BEEN DEVELOPED BY METEOROLOGISTS IN HONG KONG AND OTHER COUNTRIES AND HAVE BEEN EXTENSIVELY USED AT THE CENTRAL FORECASTING OFFICE OF THE ROYAL OBSERVATORY SINCE 1961.

THESE TECHNIQUES HAVE BEEN FOUND TO BE AN IMPORTANT TOOL FOR TROPICAL CYCLONE FORECASTING AND THEIR VALUE IS ENHANCED WITH THE USE OF COMPUTER SINCE THE PREPARATION TIME OF SOME OF THESE FORECASTS CAN NOW BE REDUCED FROM HOURS TO A FEW MINUTES.
