Abstract

Measurements of the atmospheric electric conductivity made in the equatorial Indian Ocean and Arabian Sea in August and September 1991 show that the value of conductivity decreases from 2.3 × 10−14 mho m−1 in the equatorial Indian Ocean, where relative humidity of the surface air is 70-80%, to 1.1 × 10−14 mho m−1 in the region of the Somali current, where relative humidity of the surface air increases to 80-90%. the inverse relationship observed between conductivity and relative humidity, in spite of showing a large scatter, is stronger in the case of negative than positive conductivity. the sharp increase in the sizes of ions and marine aerosol particles when the relative humidity exceeds 75-80% is proposed as the cause of the observed decrease in conductivity in the region of the Somali current
