Abstract
MR. H. ALLEN has contributed an article to the American Meteorological Journal for October, on the behaviour of pressure and temperature in low and high pressure systems. Recent investigations by M. Dechevrens (and others) tend to show that, while a high temperature accompanies a low pressure at sea-level, the fluctuations are reversed at some height above sea-level. Mr. Allen maintains that this conclusion is not supported by his examination of observations made on Mount Washington, where the minimum pressure does not coincide with the passage of the storm centre over the station, but lags about eleven hours behind it, and he considers that this fact explains the peculiar results obtained by M. Dechevrens. The same number also contains an article by Prof. F. Waldo, βOn the Absolute Reduction of Wind Observations at Sea.β He recommends the use of some instrument to assist the judgment of different observers, at the actual time of observation.
