Abstract

In the present work, the relationship between a heat wave event and its appearance during an ENSO event for the northern region of Peru (Tumbes, Piura and Lambayeque) was analyzed, in which the ocean-atmospheric mechanisms associated with heat waves were studied. its formation, in this sense, the calculation of percentiles was used firstly to determine the temperature thresholds of each meteorological station and identify the events of heat waves, secondly, the standardized anomaly methodology was applied, categorizing the extraordinary events ENSO , thirdly, a Pearson and Spearman correlation analysis was carried out in order to identify the relationship between the different climatic indices associated with ENSO (oceanic, atmospheric and multivariate) and the IOC (heat wave index) adapted from the anomaly formula standardized, likewise, a conceptual model was proposed for the formation of heat wave events; In this sense, the IOC was calculated and showed values of +0.76 and +1.33 in the ENSO events 1997 - 1998 and 2015 - 2016 respectively, also during the extraordinary events the IOC with the climatic indices showed a high positive correlation greater than +0.5, With the exception of the SOI atmospheric index, in addition, the relationship between IOC and SST, level of 850 hPa and 500 hPa, showed a high positive correlation greater than +0.5 in the months of January, February and March. On the other hand, the formation of heat wave events showed that when there is an anomalous entry of the westerly circulation into the tropical atmosphere, it causes the APS to enter the continent and trap the moisture from the high evaporation due to heating of the atmosphere. SST where the accumulated heat energy is radiated during the afternoon increasing the temperature and causing heat waves.
