For over two centuries, meteorologists were puzzled by the observation that atmospheric pressure in the tropics peaks at 10 a.m. and 10 p.m. nearly every day. In the late 1960s, a theory was proposed that these surface pressure variations result from waves that are generated by the sun's heating of the upper atmosphere. The waves, called solar tides, propagate to the ground as they travel around the globe. Strong support for this theory has now been presented in a study by a US-Japan team of...
