Abstract:

This atlas presents 120 plates showing the distribution of water vapor in the atmosphere of the Northern Hemisphere. There are 20 plates in terms of mixing ratio at the surface and 100 plates in terms of dew point at the surface and at the 850-, 700-, 500-, and 400-mb levels. The distributions of other measures of moisture, including vapor pressure, frost point, water-vapor density, and mixing ratio aloft, are readily obtainable from the distribution of the dew points. The plates will be useful to designers faced with the problem of estimating the effects of atmospheric water vapor on aerospace hardware and for those concerned with the operation and storage of equipment. The plates of frequency distributions, from 5 to 95 percent, are especially useful for estimating the duration or persistence of moist conditions, as illustrated by several examples.
