A two decade-long laboratory experiment tested importance of high water vapor content in silica glaze formation. Twenty years of exposing basalt rock chips to 80% and 90% levels of relative humidity revealed that water vapor alone can generate
The characteristics of water vapor transport (WVT) over China and its relationship with precipitation anomalies in the Yangtze River Basin (YRB) are analyzed by using the upper-air station data in China and ECMWF reanalysis data (developed
by European Center for Medium-Range Weather Forecasts) in summer from 1981 to 2002. The results indicate that the first mode of the vertically integrated WVT is significant whose spatial distribution presents water vapor convergence or divergence in the YRB

vapor (WV) and precipitation in summer and the precipitation conversion efficiency (PEC) over the TP are analyzed. The spatial distributions of atmospheric water vapor (WV) content over the TP in summer (June-July-August) are analyzed. Possible
connections between water vapor and precipitation are examined. Finally, the PEC over the TP is calculated and analyzed.

Sound travels faster at higher temperatures and relative humidities. It can be heard at a greater distance with a temperature inversion or when the wind direction is toward the listener. Snow and water vapor absorb sound and thus decrease

suggest that sublimation is rate-controlled by vapor transport. A time-dependent model coupling vapor concentration, air pressure, temperature and ice concentration is formulated, and the resulting equations solved non-linearly. The results mean either
that vapor transport is being slowed down by some unconsidered physical process or that the ice is much younger than 8 Ma.
