Appendix F.
REPORT OF THE DIRECTOR OF THE ROYAL OBSERVATORY, HONG KONG, FOR THE YEAR 1935.
I. GROUNDS, BUILDINGS AND INSTRUMENTS.
The Nakamura pluviograph was replaced on October 14th by an instrument of similar type constructed by Messrs. Casella & Co., Ltd.,
II. METEOROLOGICAL OBSERVATIONS.
2. Automatic records of the temperature of the air and evaporation were obtained with the resistance thermometers and thread recorder. Direction and velocity of the wind were recorded with Beckley and Dines-Baxendell anemographs, rainfall by Nakamura and Casella pluviographs, sunshine by a Campbell-Stokes universal recorder and barometric pressure by a Marvin barograph. Eye observations of barometric pressure, temperature and cloud were made hourly, and of the direction of cloud motion every three hours. Observations of pilot balloons were made with a Watts 1 inch prismatic theodolite at 9h. a.m. and 3h. p.m. when conditions were favourable.
3. The principal features of the weather in 1935 were:-
(a) A deficiency of sunshine. The total duration of sunshine for the year was 1714 hours, which is 253 hours less than normal. In spite of the abnormally cloudy weather, rainfall was deficient, amounting to 71.82 inches against a normal of 85.16 inches.
(b) A spell of unusually cold weather at the end of September, when a minimum temperature of 65.2°F was reached. This is the lowest temperature ever recorded in September.
(c) The absence of typhoons seriously affecting the Colony. The maximum wind velocity recorded was 63 m.p.h. on October 7th, when a typhoon was passing about 140 miles to the south of Hong Kong on a W.N.W. track.
4. The tracks of 20 typhoons which occurred in the Far East in 1935 are given in a plate which will be included with the Meteorological Results for 1935, now in the press. The following table gives a summary of the meteorological data published monthly in the Government Gazette during the year:-
