1992: Relationships between tropospheric water vapor and surface
temperature as observed by radiosondes. Geophys. Res.
Lett., 19, 1839-1842.
Using radiosonde data from 50 stations for 1973-1990, we
quantify relationships between surface air temperature (TS) and
precipitable water (W) for different time scales. Monthly mean
observations are fairly well described by an equation of the form ln
W = A + B TS, but the coefficients A and B depend on the
considered. At high TS, the relationship is poor. This relationship
and relationships between sea surface temperature (SST) and W
based on satellite microwave observations over oceans are in
remarkably good agreement over restricted SST ranges. Monthly
and annual anomalies of W and TS are well correlated only outside
the tropics, but on longer time scales, there is some evidence of
positive trends in both W and TS at most stations studied. Thus the
relationship between W and TS depends on the time scales and
geographic region considered.
