Fig 1. (a) The difference of deuterium isotopologue between
liquid and vapor (ΔD= δDliquid- δDvapor)
plotted against the saturation index (Si) for
experiments undertaken at Ahmedabad. (b) Similar plot for
18O.
Fig 2. Demonstrates the development of the concentration
gradient from initial time (to) to final time
(tf). The region (S) shaded in gray denotes the micron
thin supersaturated boundary layer near the surface of the metallic cone
used for condensation. Here we have
ev2>ev1>ev’
and
ei2>ei1>ei’
where ev and ei are ambient and
saturation vapor pressure over water.
Fig 3. (a) The predicted δD values are plotted and are found to
be in good agreement with the observed vapour values for Ahmedabad; (b)
The predicted δ18O values are plotted and are found to
be in good agreement with the observed vapour values for Ahmedabad.
Fig 4. (a) The predicted δ18O values are
plotted and are found to be in good agreement with the observed vapour
values for Hyderabad; (b) The predicted δ18O values
are plotted and are found to be in good agreement with the observed
vapour values for Roorkee.
