Stable isotopic composition of water vapor in the tropics Academic Article uri icon

abstract

  • Water vapor samples collected during tropical field experiments at Puerto Escondido, Mexico, near Kwajalein (KWAJEX), and near Key West, Florida (CAMEX 4), were analyzed for their stable isotope contents, approached isotopic equilibrium with seawater during quiescent weather or in regions of isolated or disorganized convection. Lowest 18O values occurred in or downwind from regions of organized mesoscale weather disturbances and ranged as low as 15 below isotopic equilibrium with seawater. The mean 18O value of vapor over the sea surface therefore decreases as storm activity and organization increases. Copyright 2004 by the American Geophysical Union.
