A two decade-long laboratory experiment tested importance of high watervapor content in silica glaze formation. Twenty years of exposing basalt rock chips to 80% and 90% levels of relative humidity revealed that watervapor alone can generate
The characteristics of watervapor 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 watervapor 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 watervapor (WV) content over the TP in summer (June-July-August) are analyzed. Possible
connections between watervapor and precipitation are examined. Finally, the PEC over the TP is calculated and analyzed.
By using the observed monthly mean temperature and humidity datasets of 14 radiosonde stations and monthly mean precipitation data of 83 surface stations from 1979 to 2008 over the Tibetan Plateau (TP), the relationship between the atmospheric water

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 watervapor absorb sound and thus decrease

Here the AA. present 2 nearly continuous time-series of δD and δO 18 of atmospheric watervapor (δv) measured at hourly intervals in surface air in Beijing and above a winter wheat canopy in Shijiazhuang using in-situ measurement technique. During
the precipitation events, the δv values in both Beijing and Shijiazhuang were in the state of equilibrium with precipitation water, revealing the influence of precipitation processes. These datasets highlight also how the atmospheric processes, such as air mass

This study quantificationally analyses the interaction between evaporating water body and atmosphere, and the influences of different factors on the evaporation by probing into the fractionation mechanism of stable isotope as water body is vaporized
Discussion of various misconceptions of students and the general public that include : water always freezes at O deg. C.; on days of high humidity, the air is heavy due to watervapor content; lightning does not strike the same place twice
; cataclysmic volcanic eruptions always produce large steep-sided cones; and water flows only downhill. - (DWG)
