الصفحة ii - That, once the poet's theme, the muses' boast, Now lie in ruins, in oblivion lost ! Did they, whose sad distress these lays deplore, Unskill'd in Grecian or in Roman lore, Unconscious pass...
الصفحة 71 - 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 centre or axis, and of the accompanying rain.
الصفحة 147 - SE, and continued increasing with accumulated violence until four in the afternoon, when it veered to the sovth, and became a perfect tempest, which lasted in force until near eight; it then abated. The sea during the last period exhibited a most awful scene; the waves swelled to an amazing height, rushed with an impetuosity not to be described on the land, and in a few minutes determined the fate of all the houses in the Bay.
الصفحة 136 - April the 29th,(the firstd ay of the fresh north-easterly winds), and May the 3rd, (when the gale was at its height, and the wind began to draw to the southward of west) the mercury had fallen 6-tenths. The change of current did not precede the wind, but changed with it ; when the gale was strong from NW and WNW the current ran a knot an hour to the SE, and when the wind changed to SW it ran with the same velocity to the NE The west coast of New Holland is at times visited by sudden squalls, resembling...
الصفحة 157 - SE, for some time before the wind shifted to that point. I felt so confident from that circumstance that I should have the hardest of the storm from that quarter, that I continued to lay to on...
الصفحة 138 - Card and with attention to what has been said in the preceding paragraphs, it will be seen at once why this difference is made.
الصفحة 240 - I have observed one pass over Canton river, in which the water ascended like a water-spout at sea, and some of the ships that were moored near its path, were suddenly turned round by its influence.
الصفحة 2 - Thus then it appears that these tempests or hurricanes are tornadoes, or local whirlwinds, and are felt with at least equal violence on the sea-coast, and at some little distance out at sea.
الصفحة 129 - 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...
الصفحة 160 - It is also probable that the vortex or rotative axis of a violent gale or hurricane, oscillates in its course with considerable rapidity, in a moving circuit of moderate extent, near the centre of the hurricane ; and such an eccentric movement of the vortex may, for aught we know, be essential to the continued activity or force of the hurricane.
