(7) Caution. The position indicated by the latitude and longitude signals does not purport to be the position of the centre of the typhoon, but merely the centre of a circle of specified radius within which the centre of the typhoon is believed to lie.
(8) In the China Seas Code the Time Signal (Table 4) indicates the time at which the warning was issued. In the present code it shows the time at which the typhoon or depression was in the position indicated. The table has been expand- ed as observations are now available from certain stations at 11h and 17h. Symbol No. 9 provides for occasions when the centre has been located from observations at other than routine hours.
(9) The code can also be used for the "general inference" following a synoptic message.
Thus-An auticyclone, central in latitude 36° N. and longitude 110° E. is strengthening and moving eastward, and the depression appears to be stationary in latitude 22 N. and longitude 104° E., but the position is only approximate,
clair.
