    • Abstract


      We construct climate networks based on surface air temperature data to identify distinct signatures of climatic phenomena such as cyclones, El Niño and La Niña events which trigger many climatic disruptions around the globe with serious economic and ecological consequences. The climate network shows a discontinuous phase transition in the size of the normalised largest cluster and the susceptibility during cyclones. The correlation matrix of the network shows a structure which has distinct characteristics of El Niño events, La Niña events, and no events. We also identify the signature of the El Niño and La Niña oscillations in the heat map of the system. We discuss further analysis of these systems
