Abstract
THE suggestion by C. S. Ramage1 that, in low latitudes, winds and consequently vertical motion and weather cannot be deduced from the pressure distribution is not new and is at present generally true. The coriolis force is small in low latitudes and vanishes at the equator, but the horizontal pressure forces are also normally small. If the pressure distribution is steady a large measure of balanced flow could be achieved under certain conditions. The smallness of the coriolis force only implies that it takes correspondingly longer than in middle latitudes to effect adjustment.
