Results show that although the drops' average shape is not significantly affected, the magnitudes of drop oscillations decrease when these are formed from the water polluted with sulphate/nitrate salt. However, when these polluted drops are placed in a horizontal electric field, their oblateness increases with respect to that of the distilled water drops, and this increase in oblateness is more in higher electric fields. Results can possibly be explained because of the increase in surface tension, viscosity and density, and a more dominant effect due to the increase in electrical conductivity of the polluted water. Significance of the results is discussed in view of the possible modification of lightning activity in clouds formed over big cities.</p>1 aBhalwankar, Rohini, V.1 aKamra, A., K.  uhttps://library.ncl.res.in/content/wind-tunnel-investigation-distortion-polluted-water-drops-horizontal-electric-fields-0
