Beschreibung

The Law of Storms: The Various Phenomena by Which Their Approach Can Be Ascertained with Certainty, and Practical Directions to Mariners for the Avoidance of Their Fury is a comprehensive and authoritative guide dedicated to the understanding and navigation of storms at sea. Compiled from a wide array of scientific and maritime sources, this book serves as an essential manual for sailors, navigators, and anyone interested in meteorology. It delves deeply into the nature and causes of storms, explaining the atmospheric and oceanic conditions that give rise to these powerful natural events. The book meticulously details the signs and phenomena that precede the arrival of storms, equipping mariners with the knowledge to recognize early warnings and take appropriate action. Through clear explanations and practical advice, The Law of Storms empowers readers to interpret changes in wind, cloud formations, barometric pressure, and other meteorological indicators. It provides step-by-step instructions for avoiding the most dangerous aspects of storms, including recommended courses of action, navigational strategies, and safety precautions. The text is enriched with real-world examples, case studies, and illustrations that bring the science of storm prediction and avoidance to life. Whether used as a reference on board ship or as a study resource for aspiring navigators, this book stands as a testament to the importance of preparation and knowledge in the face of nature’s most formidable forces. Its thorough approach and practical focus make it an invaluable tool for anyone seeking to understand and survive the perils of storms at sea.

ON HURRICANES AND THE LAW OF STORMS.

In the Northern Hemisphere, when the Polar and Equatorial currents of air are alternating with each other, the regular shifting of the wind round the compass will be through S., S.W., W., N.W., N., N.E., E., S.E., S.—and the changes will take place oftener between south and west, and between north and east, than between west and north, and between east and south.

Similarly in the Southern Hemisphere, it may be inferred that when Polar currents of air alternate with Equatorial, the regular shifting of the wind round the compass will be successive through S., S.E., E., N.E., N., N.W., W., S.W., S.

This is Dove’s “Law of Gyration,” (or the law of the rotation of winds). And collecting the main points into a few general propositions, it may be laid down, that all steady winds are modified by the rotation of the earth, in such a manner that Equatorial currents of air receive a westerly deflection, and Polar currents an easterly deflection; but latitudinal currents suffer no change. The N.E. and S.E. Trade Winds are steady Polar currents. The Monsoons are alternations of a Polar and an Equatorial current, twice during the year. Therefore they are N.E. and S.W. in the Northern Hemisphere, and S.E. and N.W. in the Southern Hemisphere.

The S.W. passage winds of the Northern Hemisphere, and the N.W. passage winds of the Southern Hemisphere, are Equatorial currents.

Bodies of air set in motion from a state of rest, turn the wind-vane in the direction of the meridian as follows:

The Polar current in the Northern Hemisphere from N. to E.

The Polar current in the Southern Hemisphere from S. to E.

The Equatorial current in the Northern Hemisphere from S. to W.

The Equatorial current in the Southern Hemisphere from N. to W.

In general the winds in the Northern Hemisphere are as follows:

Those from N. to E. the Polar currents.

Those from E. to S. the transition of the Polar to the Equatorial.

Those from S. to W. the Equatorial current.

Those from W. to N. the transition of the Equatorial to the Polar.

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.
