Based on the contrasting nature of the tropics and the extra-tropics, this study proposes to carry out a dynamical downscaling experiment for North America (Mexico, the United States and Canada), using two of the CMIP6 ESMs with the “best performance” for the regions, in agreement with statistical metrics, forcing the RegCM and WRF models, and evaluating their capabilities. The regional models will run under low resolution (45 km), medium resolution (15 km) and high-resolution (5 km) nesting grids, with the highest resolution covering two domains, one over a group of river basins located in the tropical zone of Mexico (namely Actopan, Antigua, Jamapa and Nautla) and a second one over a group of river basins located in the southern province of Quebec in Canada (namely Du Nord, Doncaster, Matawin, L´Assomption, Noire, Maskinonge, Du Loup and Taureau).
Weak (strong) thermal gradient and intense (weak) convective activity characterizes the tropical (extra tropical) atmosphere. In the case of the tropics, the release of latent heat is the main source of energy in the circulations of the region; while for the extratropics are the thermal gradients, Coriolis and the momentum fluxes associated to perturbations of all scales.
Earth System Models (ESMs) are a useful tool to contribute to the understanding of global circulation and generate climate change scenarios for the following decades. The resolution of these models is adequate to describe global circulation patterns, but it is insufficient to describe the subcontinental processes important to North America, such as the effects of their abrupt orography or atmospheric processes at scales smaller than 10 km. That gap is filled up by performing dynamical downscaling which requires regional models with the potential to increase to higher spatial resolutions.

Scientific questions
What are the causes of sistematic errors in ESMs and how they could affect the calculated regional climate variability?
What could be the potential added value of convention- permitting climate simulations for precipitations and for hydrological modelling in tropical and extra-tropical regions?
