Cyclones

Abstract

“J. S. D.”, in his interesting article in NATURE for January 2 last, makes the following statement:—“Thus the cyclone was looked upon as a warm column of rising air with spirally inflowing winds at its base; the anticyclone, conversely, contained a cold core of descending air. Now we know that the opposite is in reality the truth; the cyclone has a cold core, the anticyclone a warm one”. I think it should be pointed out that this pronouncement is only correct for the troposphere, but not for the stratosphere.
