Abstract
Thunder events are common during pre-monsoon season (March -May). In this paper thunder events of Delhi and Guwahati for the month of May and April have been analysed with Global Navigation Satellite System (GNSS) derived precipitable water vapour and Moderate Resolution Imaging Spectroradiometer (MODIS) derived Aerosol Optical Depth (AOD) at 550 nm data. It is observed that GNSS derived precipitable water vapour have the potential to nowcast or characterize the mesoscale event. In all cases the AOD and Integrated Precepitable Water Vapour (IPWV) increases before the thunder event which accompanied with duststorm and consequently increase the aerosol loading in the atmosphere. The rate of increase of IPWV (d/dt(IPWVdt)) is observed approximately 3-4 mm /hour during the convective initiation and relative increase of AOD is 150-300 %. The various thermodynamic parameters of radiosounding to understand better the thunder activity are also highlighted in the paper.
