THE HONGKONG GOVERNMENT GAZETTE, 12TH OCTOBER, 1895. 1083
After the passage, to the S of Hongkong, of the small depression of August 31st pressure increased slightly on the SE coast of China but in Luzon. where the barometer remained yet about 0.15 inch below the normal, a further slight decrease of pressure had set in on September 1st.
It appears from the observations made on board vessels that a band of low pressure was also lying across the China Sea in an ENE and WSW direction. This elongated depression apparently extended from the Annam Coast across Central Luzon to the Pacific, and it is probable that a cyclonic depression was forming on September 1st in the Pacific part of the above mentioned area of low barometer, perhaps around the position 18, 127°.
The following were the conditions prevailing on this day. On the SE coast of China the barometer stood at about 29.71 moderate to light NE breezes prevailing between Foochow and Hainan; in the middle part of the China Sea between 12° and 17° Lat. the barometer read about 29.64 light variable airs prevailing; off the Cochin China coast in 9° to 10° Lat. (barometer 29.73) moderate and fresh W and SW breezes prevailed accompanied by showery weather; at Bolinao light variable breezes were blowing (barometer 29.64) aud at Manila (barometer 23.67) light to moderate S and WSw breezes were accompanied by rainsqualls. The bark Japan situated in the Pacific in 15° 09′, 136° 00′ experienced moderate S winds with wet squally weather, the barometer being steady at 29.74.
The disturbance may possibly have been situated in 1949, 125° at noon on the 2nd moving towards the NW. A further slight decrease of pressure had taken place at Bolinao (29.60) and Manila (29.65) winds being light and gentle breezes from SE at the former and from S at the latter station. The barometer had risen slightly near Foochow (Sharp Peak 29.76) and was steady at Hongkong (29.71), but the NE winds had freshened on this part of the China Coast. From observations made on board the S.S. Ask lying at Anping (S. Formosa) it is seen that the disturbance was advancing towards S Formosa from the SE. The barometer on board this vessel showed a decisive fall on this day from 29.74 at 8 a. to 29.56 at 4 P. At the same time the wind, which had been light and variable during the morning, freshened somewhat from NW in the afternoon.
Next day, the 3rd, at noon, the barometer having fallen to 29.36 with the wind a fresh breeze from N accompanied by rain, the Ask left Anping to take shelter at the Pescadores. The centre was probably situated in 21, 122 at this time. Since the previous day pressure had given way to the extent of about 0.1 inch at Sharp Peak (29.66) and Amoy (29.60). The fall was less marked at Hongkong (29.66) while at Bolinao (29.61) and Manila (29.67) the barometer had commenced to rise slowly. Pressure was highest, 29.9 to 30.0 inches, over Japan and in the extreme SW part of the China Sea. Winds were strong breezes from E to ESE off the SW coast of Japan; strong breezes to fresh NNE gales off the E Coast of China and in the N part of the Formosa channel; moderate breezes from N ́and NNW off the S Coast of China and strong breezes from SW at Manila. The S.S. Ask experienced a strong N by E gale on the passage from Auping to Ponghou harbour (Pescadores) during the evening of this day, the barometer remaining, however, practically steady
since noon.
On the 4th the centre was probably situated on the E Coast of Formosa and in 24°, 1214° at noon. We have no observations made in Formosa, but accounts from there show that a very severe typhoon which caused great damage ashore and afloat passed over Keelung and Tamsui, the northern ports, during this day.
The greatest decrease of pressure since the previous day was shown at Sharp Peak (29.50) the fall amounting to 0.16 inch in the 24 hours. The barometer had now commenced to fall at Shanghai (29.78) and in SW Japan (Nagasaki 29.85). At Hongkong (29.60) the barometer was steady and inclined to rise while in Luzon (Bolinao 29.65) a decided rise had taken place. Winds were strong NNE breezes at Sharp Peak, moderate breezes from NNW between Amoy and Hongkong and strong SW breezes in Manila. A very high temperature with low humidity and almost clear skies prevailed on the coast between Amoy and Hongkong. Tlie S.S. Ask in Poughou harbour (Pescadores) had a strong N gule with rainsqualls (bar. at 1 p. 29.32) during the greater part of the day. The barometer which had been practically steady the whole day began to rise late in the evening the wind at the same time moderating. At 10 p. it backed to W and fell light.
On the 5th at noon the centre was situated in 27°, 122° and it had already commenced to recurve towards the NE. Its speed during the previous 24 hours had been at the rate of about 9 miles per
hour. The disturbance was now of great dimensions and determined the wind circulation from W. Japan in the NE part of the system to the Cochin China Coast in the SW. The isobars which were oval shaped were very much elongated towards the SW. Winds were in accordance. The worst weather was felt over a considerable area in the N semicircle where the isobars lay closer together, the gradients being therefore correspondingly steep. The following are the observations.
made at a few coast stations on the 5th:
