Abstract : A spectral analysis of northward heat transport in the northern hemisphere was performed by the Fourier analysis method. This method was applied at 500 mb, 100 mb and 25 mb for five-day intervals from October 5, 1959 through March 28, 1960. A comparison of stratospheric warmings of this period with those of the previous year studied by Boville (1961), revealed that the heat transport could be accomplished mainly by wave numbers one and/or two. From 500-mb, 100-mb and 25-mb timesections of northward heat transport, divergences were determined to calculate the local temperature time derivatives. These derivatives were in turn compared with the actual time-sections of mean temperature. This comparison showed that, due to strong convergence of northward heat transport, the winter stratosphere at high latitudes had a net ascending motion. (Author)
