Variation of mean, maximum and minimum air temperature, dewpoint temperature and scalar mean wind speed at the surface and at five levels in the troposphere, namely 1000, 850, 500, 300, and 100 hPa levels over Kerala were studied using data at eight stations during drought and normal rainfall years. The general features of the variation in temperature and wind series are compared and discussed for drought and normal years. Dewpoint temperature showed a decrease during drought years. The rate of cooling increased with height. Upper atmospheric layers showed a decrease in temperature during drought years. The cooling of the upper troposphere and the decrease in dewpoint temperature result in drought in Kerala. © 1997 by the Royal Meteorological Society. Int. J. Climatol . 17: 765–777, 1997.
