Abstract: En el presente trabajo se analizó la relación que existe entre un evento de ola de calor y su aparición durante un evento ENSO para la región norte del Perú (Tumbes, Piura y Lambayeque), en la cual se estudiaron los mecanismos océano-atmosférico asociados a su formación, en ese sentido, se empleó en primer lugar el cálculo de percentiles para determinar los umbrales de temperatura de cada estación meteorológica e identificar los eventos de olas de calor, en segundo lugar se aplicó la metodología de anomalía estandarizada categorizando los eventos extraordinarios ENSO, en tercer lugar se realizó análisis de correlación de Pearson y Spearman a fin de identificar la relación entre los diferentes índices climáticos asociados al ENSO (oceánico, atmosférico y multivariado) y el IOC (índice de olas de calor) adaptado de la fórmula de anomalía estandarizada, asimismo, se planteó un modelo conceptual para la formación de eventos de olas de calor; en ese sentido se calculó el IOC y mostro valores de +0.76 y +1.33 en los eventos ENSO 1997 – 1998 y 2015 – 2016 respectivamente, asimismo durante los eventos extraordinarios el IOC con los índices climáticos mostro una alta correlación positiva mayor de +0.5, a excepción del índice atmosférico SOI, en adición, la relación entre IOC con la TSM, nivel de 850 hPa y 500 hPa mostro una alta correlación positiva mayor de +0.5 en los meses de enero, febrero y marzo. Por otro lado, la formación de eventos de olas de calor se apreció que cuando existe un ingreso anómalo de la circulación de los oestes a la atmósfera tropical genera que el APS ingrese a continente y atrapando la humedad proveniente de la alta evaporación por calentamiento de la TSM donde la energía calorífica acumulada se irradia durante la tarde incrementando la temperatura y ocasionando las olas de calor.
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.
