Abstract

Atmospheric water vapour plays vital role in weather and climate of the earth. It is also a key parameter for designing the weather model or forecast model for atmospheric extreme events. Accurate measurement of water vapour is essential requirement for any weather model. In this paper, we have derived the local expression for relating water-vapour-weighted mean temperature and surface temperature for different radiosonde sites over the Indian subcontinent. The local expression is used to determine the precipitable water vapour (PWV) over the Indian stations. The study presented here improves the characterization of one crucial element of the hydrologic cycle, the atmospheric water vapour over the Indian subcontinent.
