Heatwaves have become more frequent and intense during the recent past. Adverse effects of heatwaves include deterioration of health, crop failures, infrastructural damage and disruption of transportation. Heatwaves are not only limited to land but have increasingly been detected in the marine environment. Marine heatwaves cause coral bleaching and have serious repercussions on local fisheries. Despite a multitude of studies being carried out independently on terrestrial and marine heatwaves, very little has been done on investigating any association between the two. Extreme events compounded by one another may create greater disruption than an extreme event that occurs in isolation. Understanding how these events are linked to each other will help forecast such events, thereby enabling communities to be better prepared for them. There is a notion that terrestrial and marine heatwaves may have common drivers or may influence each other. For example, a recent study had identified common drivers behind the marine heatwave that developed in South Atlantic during the summer of 2013/14 and high heat events over South America (Rodrigues et al., 2019). This presentation will explore the possibility of establishing a link between marine heatwaves and extreme heat events across adjacent landmasses.  We will identify these compound heat events using the Perkins and Alexander (2013), and Hobday et al (2016) frameworks. We will then look at the physical mechanisms that drive these compound events, through which we will attempt to determine a link between terrestrial and marine heatwaves. Preliminary results will be presented.
