FIGURE 5.2: Time series of zonal mean water vapor profile measurements by the Microwave Limb Sounder on the Aura satellite. The colors represent a percentage change relative to the 15&176; S-15&176; N mean at each pressure level. The upward progression with time above the 140-hPa level (~ 14 km altitude) shows the vertical motion consistent with theoretical predictions.
