Computations of the Transports of Momentum, Sensible and Latent Heat across the Equator

[摘要] The momentum, sensible heat and latent heat transports for the years 1958 and 1959 were measured by using the observations of wind, temperature and humidity in the troposphere at 14 stations in the Equatorial zone.The vertically integrated momentum transport shows a flow of momentum towards the Northern Hemisphere in all seasons. The northward transfer due to the mean cell in winter is especially large. The vertically integrated transport of sensible heat and latent heat shows respectively a flow of the heat towards the summer hemisphere mainly by the mean cell. The eddy transports of heat across the equator are found to be very small. The annual sum of the vertically integrated flux of sensible heat and latent heat results in a net transfer of heat toward the Southern Hemisphere from the Northern Hemisphere.
