In 2017, extreme rain events occurred in the northern part of Peru, causing nearly 100,000 victims according to the National Emergency Operations Center (COEN). The main objective of this research was to evaluate the dynamic process of El Niño Costero, using Oceanic Indices, as well as the influence of the Intertropical Convergence Zone ITCZ. The methodology used was to analyze El Niño Costero through the selection and analysis of Oceanic Indices (EMI, TNI, ONI, 1+2, SOI and ODP), as well as the ITCZ using satellite maps from the months of January to March 2017. The results obtained indicate that the Indices; EMI, ONI, 1+2 and SOI are not adequate to determine the occurrence of El Niño Costero. The TNI Index shows the El Niño Costero, but it also shows false positives, in the case of the ODP Index it presents positive and negative phases with a cyclicity of 5 and 6 years and in its positive phase (2015-2016) El Niño Modoki was presented. which later led to La Niña Modoki and El Niño Costero. It has been determined that the occurrence of a special type of ENSO called; El Niño Modoki and its La Niña Modoki phase would have generated El Niño Costero, which, interacting with the ITCZ, produced the intense rainfall that occurred throughout the country. Likewise, a new Oceanic Index called (IOC) has been created to monitor the periodic evolution and determine with greater precision the occurrence of El Niño Costero and implement prevention programs.
