Assessment of simulations of a polar low with the Canadian Regional Climate Model

One of the main findings of this study is that the ability of the CRCM6/GEM4 to capture the PL strongly depends on the initial conditions. In effect, only 23d12h and the latest initia- lised simulations 24d12h and 24d18h capture the development of the PL. The latter two repre- sent well the lifetime, track and size of the observed PL. In contrast, the PL represented in 23d12h is much smaller than the observed PL, and its lifetime is less than half the lifetime of the observed PL. Further, the verification of the simulations against conventional observations Fig 14. Same as Fig 13, but for 25 March 2019 at 0900 UTC and over the region to the west of the Norwegian coast. https://doi.org/10.1371/journal.pone.0292250.g014 PLOS ONE Assessment of simulations of a polar low with the canadian regional climate model PLOS ONE | https://doi.org/10.1371/journal.pone.0292250 October 5, 2023 24 / 28
