The need for cities to prepare for the increasing frequency, persistence, and intensity of heat waves (HWs) makes modeling these events essential for evaluating the effectiveness of heat adaptation strategies. We use the Pseudo Global Warming (PGW) method to project HW episodes that are simulated with the Weather Research and Forecasting (WRF) model coupled with the Building Effect Parameterization and Building Energy Model at 1 km resolution using the Metropolitan Area of Barcelona (AMB) as a case study. We assess three plausible urban adaptation strategies to reduce temperatures, heat stress and vulnerability to heat now and in mid- and late- 21st century conditions under the SSP370 radiative forcing scenario: 1) increasing rooftop albedo by white-painting all feasible rooftops; 2) implementing irrigated sedum green roofs where possible; and 3) increasing peri-urban agriculture, urban parks, and urban fraction while reducing urban forest according to the recently approved Urban Master Plan. We find that (1) provides the greatest cooling (\u22121.75 \u00b0C during daytime) in the most vulnerable areas, while (2) and (3) show moderate regulation (\u22120.37 \u00b0C and \u2212 0.26 \u00b0C respectively) and slight nighttime warming (0.24 \u00b0C and 0.31 \u00b0C). Despite these reductions, none fully counterbalance the projected 6 \u00b0C increase by 2100, highlighting the limited capacity of adaptation strategies under severe warming scenarios and providing critical insights into effective and feasible measures to mitigate heat impacts and reduce vulnerability in urban environments.<\/p>\n

La necessitat que les ciutats es preparin per a la creixent freq\u00fc\u00e8ncia, persist\u00e8ncia i intensitat de les onades de calor fa que la modelitzaci\u00f3 d’aquests esdeveniments sigui essencial per avaluar l’efic\u00e0cia de les estrat\u00e8gies d’adaptaci\u00f3 a la calor. Utilitzem el m\u00e8tode de Pseudocalfament Global (Pseudo Global Warming o PGW) per projectar episodis d’onades de calor simulats amb el model Weather Research and Forecasting (WRF), acoblat amb la Parametritzaci\u00f3 de l’Efecte dels Edificis i el Model Energ\u00e8tic d’Edificis a una resoluci\u00f3 d’1 km, utilitzant l’\u00c0rea Metropolitana de Barcelona (AMB) com a cas d’estudi. Avaluem tres estrat\u00e8gies d’adaptaci\u00f3 urbana plausibles per reduir les temperatures, l’estr\u00e8s t\u00e8rmic i la vulnerabilitat a la calor actualment i en condicions de mitjans i finals del segle XXI sota l’escenari de for\u00e7ament radiatiu SSP3-7.0: (1) Augmentar l’albedo dels terrats pintant de blanc tots els terrats viables. (2) Implementar cobertes verdes de sedum amb reg on sigui possible. (3) Augmentar l’agricultura periurbana, els parcs urbans i la fracci\u00f3 urbana, tot reduint el bosc urb\u00e0 d’acord amb el Pla Director Urban\u00edstic aprovat recentment. Observem que l’estrat\u00e8gia (1) proporciona el refredament m\u00e9s gran (\u22121,75 \u00b0C durant el dia) a les zones m\u00e9s vulnerables, mentre que la (2) i la (3) mostren una regulaci\u00f3 moderada (\u22120,37 \u00b0C i \u22120,26 \u00b0C respectivament) i un lleuger escalfament nocturn (0,24 \u00b0C i 0,31 \u00b0C). Malgrat aquestes reduccions, cap estrat\u00e8gia no contraresta totalment l’augment projectat de 6 \u00b0C per al 2100, fet que destaca la capacitat limitada de les estrat\u00e8gies d’adaptaci\u00f3 sota escenaris d’escalfament sever i proporciona informaci\u00f3 clau sobre mesures efectives i viables per mitigar els impactes de la calor i reduir la vulnerabilitat en entorns urbans.<\/p>\n
