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

surface station providing this observation is located 8.82 km from the centre, the real SLP min- imum may be lower. The SLP minimum of the PL in 24d12h and 24d18h is 995.6 and 995.7 hPa, respectively, also at 1500 UTC. The PL in 23d12h shows a steeper decrease in SLP and, as Fig 5. Track of the observed PL and of the PL in the simulations and ERA5. The markers represent the position of the PL at each hour. Information about the genesis and dissipation times of these PLs can be found in Table 1.
