WHAT CAUSES AN OVERHEAD WIRE TO WHISTLE IN THE WIND? WHAT IS AN EQUATORIAL TORQUETUM? WHY DO PEOPLE GET SUNBURNT? WHY IS THE AIR TEMPERATURE RISING IN HONG KONG BUT NOT IN MACAU?

-

THE ANSWERS TO THESE QUESTIONS AND A LOT OF OTHER FASCINATING INFORMATION - CAN BE FOUND IN THE 1981 EDITION OF THE ROYAL OBSERVATORY CALENDAR WHICH IS NOW ON SALE.

PRICED AT $20, THE BILINGUAL CALENDAR CAN BE OBTAINED FROM THE GOVERNMENT PUBLICATIONS CENTRE, GPO BUILDING, CONNAUGHT PLACE, CENTRAL THE ROYAL OBSERVATORY, NATHAN ROAD, KOWLOON- AND LEADING BOOKSHOPS ON BOTH SIDES OF THE HARBOUR.

MAKING METEOROLOGICAL AND SCIENTIFIC DATA EASY TO UNDERSTAND IS A MAJOR FUNCTION OF THE CALENDAR WHICH IS ALSO PRODUCED TO ACKNOWLEDGE THE WORK OF VOLUNTARY OBSERVERS AND SIGNAL STATION OPERATORS.

THE KING-SIZE CALENDAR CONTAINS A SEPARATE PAGE FOR EACH MONTH OF THE YEAR AND COLOUR ILLUSTRATIONS AND DIAGRAMS ARE USED TO EXPLAIN PARTICULAR TOPICS OF INTEREST.

CONTRIBUTIONS TO THE CALENDAR HAVE BEEN MADE BY SCIENTIFIC STAFF AT THE ROYAL OBSERVATORY AND IT HAS BEEN EDITED AND DESIGNED BY THE GOVERNMENT INFORMATION SERVICES.

AS WELL AS THE USUAL DATE INFORMATION THE CALENDAR CONTAINS A TIDE TIME-TABLE, MOONRISE AND MOONSET TIMES, SUNRISE AND SUNSET TIMES, AND THE MONTHLY NORMS FOR AIR TEMPERATURE, RELATIVE HUMIDITY AND CLOUD CONDITIONS. IT ALSO GIVES THE LUNAR DATES OF THE CHINESE CALENDAR.

A SPOKESMAN FOR THE GOVERNMENT PUBLICATIONS CENTRE SAID THAT PAST EDITIONS OF THE CALENDAR HAD EVOKED WIDESPREAD INTEREST AND IT WAS ANTICIPATED THAT THERE WOULD BE A STRONG DEMAND FOR THE 1981 EDITION.
