On the 19th August the barometer showed a further rise on the entire coast. and variable breezes, chiefly SE, on the SE coast, moderate SE breezes on the E coast. generally fine except in the Southern part of the Formosa Channel where showers prevailed. The barometer had risen at the easternmost stations on the Yangzte, but had fallen slightly at Ichang (baro- meter 29.57 at noon). The wind had veered since the previous day and was now from SE light to moderate breezes at Wuhu (barometer at nnoo 29.66) and Kiukiang (barometer at noon 29.64). At Hankow (barometer 29.47), it was E 1 increasing to E 3 at night and veering to SE 3 on the morning of the 20th. The weather was fine at all these stations.
On the 19th August, therefore, there yet remained some indications of the late typhoon which had now become a feeble depression. The centre may have been on the 19th at noon in 281°, 113°
The average isobars, wind forces and directions from 9 p. on the 16th August to 9 p. on the 17th are shown in figure 2. The averages are in this case influenced by the circumstance that on the 16th the centre was on the east coast of Formosa, while on the 17th it was in the Formosa Channel. It entered the coast of China about 3 p.
The average angle between the wind and the radius was at 100 miles distance from the centre as follows:-68° to the N of the centre, 50° to the W, 47° to the S, and 58° to the East. This angle was greatest in the right-hand semi-circle, the centre moved NW by Wward. At a distance of 30 miles from the centre the angle was 69°, at 75 miles 52°, at 125 miles 57°, and at 200 miles 32°. The average angle between the wind and the radius was 54° i.e. the incurvature was 36° or about 3 points.
The radius of the calm area was about 5 miles. Within 20 miles it blew more than force 7, but the observations do not agree about the greatest force. Only the Lennox reported full typhoon force. Between 30 miles and 50 miles from the centre it blew with force 6, at 75 miles from the centre with force 7, at 125 miles from the centre with same force, and at 200 miles from the centre with force 5. It is a curious fact that it blew at a distance from the centre on an average harder than nearer the centre, but such is sometimes the case when the centre is near the shore.
There was a very heavy sea to the N and NE of Formosa, with came from the quarter where the typhoon originated in the Pacific. centre in front of the centre and within 200 miles behind the centre. in Europe where the rainy area stretches out in front of the centre. the centre beyond 150 miles.
