Figure 8.10: Global distribution of the vertical-mean meridional (northward) transport of
water vapor by all motions (a) and transient eddies (b) in m S-1 9 kg- l for annual-mean
conditions. To convert to cp in units of 10 kg m- l S-I, multiply by Po/g (r:::; lover oceans and
low-level land) (from Peixoto and Oort, 1992).
surface up into the lower stratosphere over both ocean and land in clear and cloudy conditions
with enough time and space resolution to separate the various dynamic and cloud processes that
affect the transport and abundance of atmospheric water vapor. Improvements could be made
with instruments measuring more complete infrared and microwave spectra. The limitations of
other instruments arise both because the emission spectrum from water vapor is complicated
