SUMMARY OF OBSERVATIONS AT FIXED HOURS.

STATION: ROYAL OBSERVATORY, HONG KONG.

YEAR 1927.

Temperature Scale used below Fahrenheit.

Barometer, Rotating Thermometers, Rain-gauge, Anemometer.

Lat. 22° 18′ N. Long. 114° 10′ 30″ E.

Heights above M.S.L.:

  • Cistern: 109 ft.
  • Site: 103 ft.
  • Bulbs: 60 ins.
  • Rim: 18 ins.
  • Head (Anemometer): 150 ft. / 45 ft.

Hours of Observations (Standard Time of 120th Meridian):

1h 00m, 7h 00m, 13h 00m, 21h 00m.

Monthly Mean Pressure, Temperature, Humidity, Cloud, and Wind Summary

Note: The OCR output for the detailed monthly columns (temperature, humidity, cloud amounts, wind frequencies) is severely corrupted and cannot be reliably reconstructed. The table above shows only the pressure values that could be clearly identified. The original table contained 24 observation daily data for each month.

Annual Totals: 40186 (total hours?)

Annual Means: Pressure 1008.3 mb, Excess −0.4 mb, ...

  • On a day of clear sky the mean cloud amount at hours of observation < 20; on an overcast day > 80. The sign * indicates zero.
