Fig. 3: Projected changes in frequency of transboundary warm-season heatwaves under high-emissions scenario.
From: Frequent land-ocean transboundary migration of tropical heatwaves under climate change
a, b Maps show projected relative changes in frequency of ocean-to-land heatwaves (a) and land-to-ocean heatwaves (b) based on CMIP6 under SSP5-8.5 during 2041–2080 compared to historical simulations during 1981–2020, respectively. c, d The same as (a, b), but based on CESM-LENS under RCP8.5 during 2041–2080 compared to historical simulations during 1981–2020. Dots show that more than 80% of the models (a, b) and ensemble members (c, d) agree on the changes in frequency across CMIP6 models and CESM-LENS ensemble members, respectively. Hatching indicates the region where the absolute signal-to-noise ratio ( | SNR | ) > 1 (see Methods).
