Title: Marine heatwaves analysis thru climate models based on the CMIP5 program and observational data

Abstract: Sea Surface Temperature (SST's) representation  over the worlds oceans varies across models. Climate models built-in functions over-estimate the representations of  SST's in some regions and do the opposite in other ones. This builds up uncertainty around models skills to effectively represent climate modes and the ability to assess climate phenomena like Marine Heatwaves (MHWs). The present study compares 8 different climate models performance of SST's throughout a time-series that spans 150 years and compares it to an observational dataset with 156 years of length to assess the appearance of MHWs. The analysis is done over 9 different regions across the globe with particular focus on the El Niño Southern Oscillation due to its influence as a climate mode to the rest of the ocean regions.
