On Displacements And Intensity Changes Of Atmospheric Vortices
Aerological investigations conducted during the last few years have
revealed that the long, meandering disturbances characteristic of the
middle latitude belt of westerlies in the upper troposphere frequently
increase in amplitude until troughs and ridges finally are cut off from
the main current, thus forming cold cyclonic vortices on the equatorial
side of the west-wind belt and warm anticyclonic vortices on the north
side thereof. True vortices, with nearly vertical axes, are thus
characteristic phenomena not only of equatorial regions where they
appear as tropical cyclones but also of middle latitudes.
