Atmospheric rivers in CMIP5 climate ensembles downscaled with a high-resolution regional climate model

Abstract: Abstract. Atmospheric rivers (ARs) are important drivers of hazardous precipitation levels and are often associated with intense floods. So far, the response of ARs to climate change in Europe has been investigated using global climate models within the CMIP5 framework. However, the spatial resolution of those models (1–3∘) is too coarse for an adequate assessment of local to regional precipitation patterns. Using a regional climate model with 0.22∘ resolution, we downscaled an ensemble consisting of 1 ERA-Int… Show more

“…In Galicia, located in the northwest region of the IP, this percentage is slightly lower owing to the greater amount of precipitation that is associated with other phenomena, like cold fronts. These results are similar to those obtained by Gao et al (2016) and Gröger et al (2022) at the regional scale and are also consistent with the findings of Baek and Lora (2021) for the IP at a global scale. The ARCI experiment exhibits the highest percentage for the entire domain, which can be attributed to the interactive introduction of various types and concentrations of aerosols acting as CCN in this simulation.…”

“…In such cases, the use of regional climate models (RCMs) with higher resolution can provide a better understanding of ARs. This is the case for the IP (Gröger et al, 2022), which is characterized by a complex orography. Nevertheless, it should be taken into account that the spatial tracking given a fixed time step method may not be suitable for data obtained from RCMs whose spatial limits are very close to the detection area.…”
