Not illustrated. 1873 Excerpt: ...fury, lashing the surface of the sea into drifting spray, and destroying ships, houses, and every thing that lies in its path. Cyclones in the northern hemisphere rotate in a direction contrary to that of the hands of a watch, and progress first in a north-westerly, then in a northeasterly, course. In the southern hemisphere, they revolve in the same direction as the hands of a watch, and move at first toward the south-west, and afterward to the south-east. These rotary and progressive motions are shown in Figs. 23 and 24. Flo. S3. Flo. 24. 37. Wind-zones.--To mark the distribution of winds, geographers distinguish the following wind-zones, the extent of which may be seen on Map V.: --77(e Zone of Calms, following the line of greatest heat near the equator. Here there is a continual ascending current, and either calms prevail, or short gusty winds, constantly changing in force and direction; thunder-storms are frequent and violent. The Zones of the Trade-winds, one north, the other south, of the Zone of Calms. The Sub-tropical Zones, in which the trades prevail in summer, and variable winds in winter. As the position of the sun changes with regard to the equator, the position of the zones mentioned above changes with it, the trades being thrown farther north in the northern summer, farther south in the southern summer. The regions subject to this change constitute the Sub-tropical Zones. The Zones of Variable Winds, lying beyond the two last mentioned. In these, the anti-trades predominate in the lower latitudes, blowing from the south-west in the north zone of varia subject to their visitations? Where else do they occur, and when r By what is the approach of a cyclone usually announced? Give an account of the motions of a cyclone in the northern hemisphere...
