Exchange between water droplets and tritiated water vapour

“…The soundings demonstrate several problems that may arise if tritium were used to trace water vapor through a storm. Since the concentration of tritium does not vary greatly within the first 5 km, processes such as fractionation during condensation and the molecular exchange of water vapor between raindrops and their environment (Bolin, 1958;Booker, 1965) may cause changes in the precipitation concentration of the same order of magnitude as the variations of tritium with different elevations.…”

A series of 16 aircraft soundings was made during the summers of 1966 and 1987 to measure the vertical distribution of tritium in water vapor from the surface to an altitude of 6 km. Three types of tritium distributions were found. The type I soundings showed a generally increasing tritium concentration with increasing height. Type I1 soundings were characterized by a constant tritium concentration with increasing altitude. On type I11 soundings the tritium concentration gradually decreased to approximately 2.4 k m and then abruptly increased. These soundings are discussed in terms of the origin of the air masses, evapotranspiration, and the water vapor mixing ratio.(2) the origin of the air mass with respect to the stratospheric and continental sources and the oceanic sink, (3) the degree of vertical exchange, (4) the water vapor mixing ratio (MR) of the environmental air, and (5) the amount of evapotranspiration. Since most of these factors are controlled by atmospheric circulations, the T soundings may be best explained by con-Tellus XXII (1970). 6

“…As a result of the rapid exchange of isotopes between the rain droplets and ambient vapour (Bolin, 1958;Booker, 1965), the falling rain drops contribute tritium to the lower tropo sphere during the period where strong vertical tritium gradients exist. Moreover it is the vehicle for the downward trans port of tritium within the troposphere.…”
