“…Heat advection accompanying these systems can further enhance surface temperatures (e.g., Gibson et al, 2017;Miralles et al, 2014Miralles et al, , 2019Schumacher et al, 2019), with this process defined by both the large-scale synoptic conditions and the characteristics of the surface over which the atmospheric flow passes. Considerable research has also examined how land surface conditions contribute to local amplification of temperatures during heatwaves (e.g., Fischer et al, 2007;Gibson et al, 2017;Hirsch, Evans, et al, 2019;Miralles et al, 2014;Suarez-Gutierrez et al, 2020). In particular, in the weeks prior to a heatwave, the absence of precipitation to recharge water stores within the land surface results in a shift in the surface energy partitioning away from latent heating towards enhanced sensible heating (e.g., Hirsch, Evans, et al, 2019;Miralles et al, 2014).…”
