Atmospheric blocking and their associated extreme weather challenge the current climate models. Two next generations of storm-resolving Earth system Models (nextGEMS) try to reduce these biases by improving resolution. These changes lead to a better representation of mesoscale processes.
Here, we evaluate how the large-scale flow can benefit from the higher grid-resolution. Recent studies have proved the relevance of the diabatic
processes for the block formation and intensification. Ascending Warm conveyor belts (WCB) airstreams transport air masses with negative potential
vorticity (PV) anomalies into the upper-level ridge associated with the block and contribute to its intensification
