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.

The recent research published by the National Centre for Earth Science Studies NCESS studies the flood risk zones in the Thamirabarani river basin (TRB) in Tamil Nadu, India, which is becoming more susceptible to flooding, especially during the northeast monsoon. The study highlights the need for continuous monitoring, sustainable urban planning and community-based disaster risk reduction efforts to enhance flood preparedness.

Discover latest research led by the National Centre for Earth Science Studies NCESS examines soil erosion and sediment yield in Kerala's Karamana RiverBasin using GIS-based RUSLE (Revised Universal Soil Loss Equation) and SDR (Sediment Delivery Ratio) models, focusing on the effects of rainfall, land use and land cover. It offers critical insights into soil conservation and sustainable development for tropical river basins facing global climate change. The findings highlight how extreme climatic events, such as heavy rainfall, significantly increase soil erosion in low and medium-risk areas, underscoring the importance of proactive erosion control measures.
