Dive into the intriguing findings of a recent study by the National Centre for Earth Science Studies (NCESS) that assesses the spatial distribution and severity of soil erosion in the Thamirabarani River Basin (TRB), located in southern India, using the RUSLE model integrated with GIS and Remote Sensing techniques. The study identifies key erosion hotspots and presents a suite of targeted conservation strategies, including afforestation, contour ploughing, and the construction of check dams. Perhaps most impressively, it offers a detailed erosion risk map that is vital for sustainable watershed management and crafting climate-resilient soil conservation strategies in the TRB.

A fascinating new study from the National Centre for Earth Science Studies (NCESS) unveils intriguing insights into the climate history of the Western Bay of Bengal over the last 45,000 years. By employing a multiproxy approach, researchers reveal how solar and orbital forcings have been key players in monsoon variability, which in turn affects vital oceanographic processes. The findings illustrate a dramatic interplay between phases of robust Indian Summer Monsoon and periods of retreat, shaping marine productivity in the region. This groundbreaking research not only uncovers the intricate relationship between local monsoon patterns and global climate dynamics but also enhances our understanding of long-term environmental shifts in this sensitive climatic area.

A fascinating new study from the National Centre for Earth Science Studies (NCESS) is shedding light on the forces at play in the development of the Bengal Fan. The research reveals that the sedimentation processes in the Bay of Bengal are surprisingly resilient to shifts in Indian Summer Monsoon rainfall. Instead, it's the changes in sea level that have a more pronounced effect. This discovery highlights the complex interplay between climate and coastal geomorphology, showcasing how these environmental factors intricately shape the evolution of the Bengal Fan.

A new research by the National Centre for Earth Science Studies (NCESS) identified the shallow precipitating systems using collocated in-situ observations during the southwest monsoon season. The shallow precipitating systems produce heavy rain by the active collision-coalescence process. The collision-coalescence process is enhanced with the rain intensity and duration of shallow systems, as evidenced by the widening of the raindrop spectra.

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.
