HONG KONG ANNUAL REPORT, 1952

An investigation was commenced and is still in progress of the factors influencing the properties of concrete made from local materials.

In the economic and social fields, subjects of con- tinuing research include problems of industrialization in Asia, social studies in Hong Kong, and the economic history of China.

During 1952, the network of rainfall recording stations maintained by the Royal Observatory was considerably extended. After the completion of a year's measurements of evapotranspiration of water from grass, an investigation of the water needs of the more common winter vegetables was begun in October. A critical survey is being made of the possibility of a significant relationship between the ionosphere and the weather, based on three years' observations.

The following papers by members of the Observa- tory staff were published during the year :

A Brief General History of the Royal Observatory

by L. Starbuck.

Diurnal Variations of Summer Rainfall over East

China, Korea and Japan.

Variations of Rainfall over South China during

the Wet Season.

Relationship of the General Circulation to Normal Weather over Southern Asia and the Western Pacific during the Cool Season, by C. S. Ramage (American Journal of Meteorology and the Bulletin of the American Meteoro- logical Society).
