Display Area Introduction

With the development of the aviation industry in Hong Kong from the 1920s and the opening of the Kai Tak Aerodrome in 1925, the Observatory began upper air meteorological monitoring to support aviation industry needs. In 1921, the Observatory started using hydrogen-filled pilot balloons and theodolites for upper air wind observations in Tsim Sha Tsui. In 1936, the Observatory began to provide weather summaries for the Far Eastern region to the Kai Tak Aerodrome and airline companies, in addition to hourly meteorological reports. Charts of en-route meteorological reports were also prepared for the reference of pilots. The Observatory's aviation forecasting service began in 1937, followed by the full operation of the Airport Meteorological Office at the Kai Tak Aerodrome in 1939.
