Also, in the Southern hemisphere, the winds are as follows:
Those from S. to E. the Polar currents.
Those from E. to N. the transition of the Polar to the Equatorial.
Those from N. to W. the Equatorial current.
Those from E. to S. the transition of the Equatorial to the Polar.
Thus, a complete revolution of the wind-vane in the Northern Hemisphere is therefore S.W., N.E., S. with the sun, and in the Southern Hemisphere the rotation is S.E., N.W., S., with the sun, also, in that region.
When the course of a steady wind is obstructed in such a manner as to produce a Hurricane, or Cyclone, the wind has a rotary or whirling motion (as it were, on an axis), while the storm itself has a progressive motion.
N. B.—The rotation of the wind during a hurricane, in the Northern Hemisphere, is in a direction contrary to that in which the hands of a watch move. In the Southern Hemisphere, the rotation is in the same direction as that of the hands of a watch. And hence the following shiftings of the vane: In the Northern Hemisphere, when the vortex (or center) of the storm passes to the westward of the place of observation, the rotation is S.W., N.E., S., with the sun; when the vortex passes to the eastward of the place of observation, the rotation is S.E., N.W., S., against the sun.
In the Southern Hemisphere, if the vortex passes to the westward of the place of observation, the rotation is S.E., N.W., S., with the sun.
If the vortex passes to the eastward of the place of observation, the rotation is S.W., N.E., S., against the sun.
