We use WRF BEP+BEM to investigate the sensitivity of multiple heat wave periods to climate change under the SSP370 scenario. The simulations show mean temperature increases of 2.5 ºC by the mid-21st-century and 4.2 ºC by the end of the century in the Metropolitan Area of Barcelona, a Mediterranean region in northeastern Spain.

This Zenodo repository contains the following:

met_em initial and boundary conditions for the Metropolitan Area of Barcelona:met_em files including the initial and boundary conditions used for modeling a historical heatwave (2020), as well as projected PGW-MID (2070) and PGW-END (2100) periods.

wrfout_d03, model output:WRF output at 1 km resolution for the Metropolitan Area of Barcelona on August 1st, 2020 (a historical heatwave day), representing the historical, mid-century (2070), and end-of-century (2100) periods.

PGW composites:NetCDF-format plots of relative humidity (RH) and temperature (T) maximum and minimum values. These are provided for the historical control period (CTL), mid-century (MID), and end-of-century (END), across the four analyzed synoptic weather patterns (SS, SA, DA, and DAU).
