第85页 - ... might be found any course of wind, from the rotative to the rectilinear, together with varying conditions as regards clouds and rain. But I have never been able to conceive, that the wind in violent storms moves only in circles. On the contrary, a vortical movement, approaching to that which may be seen in all lesser vortices, aerial or aqueous, appears to be an essential element of their violent and long continued action, of their increased energy towards the center or axis, and of the accompanying...

第85页 - The degree of vorticular inclination in violent storms must be subject, locally, to great variations ; but it is not probable that on an average of the different sides, it ever comes near to forty-five degrees from the tangent of a circle, and that such average inclination ever exceeds two points of the compass, may well be doubted.
第146页 - November 1836, when the velocity of the wind was estimated at about 100 feet per second, the sea at Plymouth was raised three feet six and a half inches above the mean level, the greatest height above the equilibrium level he has seen. The hurricane began at SW, and the barometer was very low ; therefore this great increase in height is due both to the wind and diminished atmospheric pressure. A gale of wind from the southward, a low barometer, and a high spring-tide concurring, cause damage and...
