Mass Flux Through the Tropics
Download a postscript version of this plot: massflux.ps
This figure shows the seasonal pattern for mass flux of upward moving air (in units of 1 x 108 kg/sec) through the tropics as defined by latitudes from 10o N to 10o S. The 2 lines are the calculation done using either UARS UKMO temperatures (solid line) or the NMC stratospheric analysis temperatures (dotted line). For more information, please see Rosenlof  or contact Dr. Karen Rosenlof.
