Water resources are sensitive to climate variability. Lakes and reservoirs are the major sources of global water storage, and it is very important to understand the relationship between climate variability and the change in the terrestrial water storage (TWS) for sustainable water resource management. Thousands of artificial reservoirs, lakes, and ponds are used for storing water, and most of the major rivers are also regulated for sustainable management. Lakes can be landlocked (endorheic) or flow to the ocean (exorheic). TWS in the endorheic basins indicates the abundance of water which is an integral part of water resource management. The National Oceanic and Atmospheric Administration listed 43 climate variability indices and keep record since 1854. These records are based on the temperature and pressure change over the ocean surface. The main objective of this study is to critically explore the link between five prominent climate variability indices which are El NiƱo-Southern Oscillation, North Atlantic Oscillation, Pacific Decadal Oscillation, Indian Ocean Dipole, and Atlantic Multidecadal Oscillation, and TWS change in the global endorheic lakes. The Gravity Recovery and Climate Experiment (GRACE) data will be used to determine the TWS variation. Empirical orthogonal function and cross-correlation will be used to link the TWS variation with the climate variability indices. Several individual studies have been conducted on particular regions and indices. A global study will help to understand the variation in the global water storage in the endorheic basins and its link with the climate variabilities.
