Abstract : On any typical weather map of the world some isobars are small in size while others appear quite extensive. Around a low or a high pressure area the isobars usually appear as small closed curves, while between low and high pressure areas some isobars appear to be very long. This paper shows that some isobars must be long enough to contain an antipodal pair of points. The proof is deceptively short and simple, a condition brought about by the use of some of the most powerful tools in topology. (Author)
