CEE Seminar: Natural Decadal Climate Variability, Droughts and their Impacts on Water and Food Securities, and Implications for Sustainable Policy Development in India

Natural decadal climate variability (DCV) is one of the oldest areas of climate research. Building on centuries-long literature, a substantial body of research has emerged in the last two to three decades, focused on understanding causes, mechanisms, and impacts of DCV. Several DCV phenomena - the Pacific Decadal Oscillation or the Inter-decadal Pacific Oscillation, tropical Atlantic sea-surface temperature gradient variability, West Pacific Warm Pool variability, and decadal variability of El Niño-La Niña events - have been identified in observational records; and are associated with variability of worldwide atmospheric circulations, water vapor transport, precipitation, temperatures, river flows, crop productions, and transportation on the Mississippi River and hydro-electricity production in the U.S.; and worldwide oceanic circulations, salinity, temperatures, and fish catches.....
