Abstract: The calculation of transmission for a model spectrum requires the adoption of a distribution function for line intensity. In the case of the infrared water-vapor spectrum (random model), a logarithmic ogive distribution ...

Abstract: Harmonic analysis of mean monthly zonal wind and temperature data,after removing the annual cycle, have shown the existence of the 26-month oscillation in the equatorial stratosphere. The oscillation in temperature extends ...

Abstract: A cross correlation (by the superposed-epoch method) has been carried out between sodium abundance, measured in twilight at Saskatoon, and stratospheric warmings, observed in temperature data at Churchill and Alert. A ...

Abstract: A combination nomogram is presented for the calculation of solar altitude and azimuth for any latitude, solar declination, and time of day.

Abstract: A frontal contour chart is one portraying the topography of frontal surfaces by means of contour lines. The method of constructing the charts is briefly indicated. Frontal contour charts have been prepared on a routine ...

Abstract: A precipitation physics project aimed at discovering basic relationships in the chain of cause and effect in precipitation mechanisms was operated in western Quebec province, Canada, from 1959 to 1963 inclusive. In addition ...
