H. K. O. No. 49.

HONGKONG, OBSERVATORY, 12th February, 1881.

SIR,-Having devoted a part of my time last autumn in studying past records of the weather kept by Officers of the Harbour Department, I have the honour to submit the accompanying account of the average direction and force of the wind at Victoria Peak.

I have the honour to be,

Sir,

Your most obedient Servant,

The Honourable The COLONIAL SECRETARY,

W. DOBERCK,

Government Astronomer.

On the Mean Direction and Force of the Wind at Victoria Peak.

The Direction and Force of the Wind at Victoria Peak are estimated at different equidistant hours during the day, but no records are kept during the night. The following results are therefore not free from the influence of the diurnal variation of the Wind, but it is to be expected that that influence will be found to be comparatively insignificant.

The Mean Direction and Force (0-12) for each day was taken, and Table I exhibits the number of days during each month in three years, when the wind blew from each Direction.
