Abstract: The variation of sodium and chloride concentrations with rainfall intensity
in Hawaii was investigated in 13 trade wind showers. The variation was
found to be inversely dependent on rainfall intensity, although the ratio of Na to
Cl appeared to be independent of the intensity. Several factors which may affect
the dependence of concentration on rainfall intensity are discussed, and it is concluded
that: (1) washout and evaporation, more than any process which may occur
within the cloud, are the dominant factors in increasing the salinity of the small
raindrops collected below the cloud base, and (2) exchange of gaseous and dissolved
chlorine is a minor factor affecting the variation of chloride concentration
with rainfall intensity.
