A new collaborative research by the National Centre for Earth Science Studies (NCESS) on tropical lightning in #SouthernIndia offers key insights into its patterns and causes. Researchers analysed 5.3 million #lightningstrikes recorded between 2019–2021 from a state of the art high resolution ground based lighting location network, with most occurring during pre-monsoon seasons. Dangerous high magnitude lightning currents were observed during post-monsoon seasons, while positive lightning strikes were common before the monsoon. #Lightning within clouds was found to be more active in deep convective clouds at high altitudes (10-18 km). The study also highlights how seasonal changes, aerosol concentrations and ocean temperatures influence spatial lightning activity across the region.
