TYPHOON S (Fr, Typhous), or, more properly, TY-FOONGS.
Dangerous tempests which are liable to happen in the Chinese
Seas. They blow with greatest fury near land, and seldom reach
farther south than 14° north latitude. They frequently commence
without giving much indication of their proximity, and a series
of fine weather and calms is apt to be succeeded by a Tyfoong.
Marine barometers or sympiesometers seem to aff*ord the best
means of anticipating these tempests. From December to May
tyfoongs seldom or never occur. The remainder of the year is
subject to them ; and the most violent of these seem, of late years,
to have been experienced in the months of June and July, and
about the equinox in September.    (Horsburgh's India Directory.)
