Charts are presented showing the smoothed mean monthly diurnal height change of the 500-mb surface during 1949–51 at U. S. Weather Bureau radiosonde stations. There are brief discussions of the influence of errors in temperature measurement on the 500-mb diurnal height change and of the relation between diurnal changes in surface pressure and 500-mb height.
