The word "typhoon" has been retained as it is in general use throughout the Far East. Used in conjunction with the "intensity" signal the word "cyclone" would be preferable.
(a) The figures in Table 1 will indicate whether the figures in this column refer to a typhoon, a depression, an anticyclone or the doubtful case of "typhoon or depression".
(b) As there is no column for "continental depression" in Table 1, when this signal is sent the direction of motion will be given by means of the figures in column 2 of Table 1, so as to maintain the practice of former years.
