HONG KONG ANNUAL REPORT
Details of the year's weather are given in Chapter 22.
METEOROLOGICAL RESEARCH
Hong Kong's contribution to the International Geophysical Year consisted of additional radiosonde ascents, and both radio- sonde and radarwind ascents to very high altitudes. Special seismological records were made, and locally-registered ships voluntarily co-operated by making a large number of weather observations.
Work continued with a long-term project to determine whether afforestation may affect the run-off of surface water by increasing condensation in foggy conditions. A study of the effect of mete- orological conditions on tides and of tidal waves at Hong Kong was completed. The Radiosonde Section of the Observatory made a detailed investigation of the corrections made to radiosonde observations, and the results were published in a paper entitled Modification to Lag and Radiation Corrections for the Kew Type Radiosonde in the Troposphere.
