Interaction of monsoon with northern hemisphere mid-latitude circulation

摘要: Fourier analysis has been used for the monthly mean northern hemispheric geopotential height levels 700 mb and 300 months April through August in bad monsoon years (1972, 74 79) of good rainfall over India (1967, 73, 77). From coefficients transport momentum sensible heat have computed wave number domain. Waves 1 to 3 show contrasting features during monsoon. Northward across subtropical latitudes is larger years, while northward years. In there a large divergence subtropics convergence mid-latitudes. sub-tropics, but These quantities similar pre-monsoon (April May)
