The development of Tropical Cyclone Diana (1984) is simulated with a mesoscale model using 1.2 km grid spacing over a regional‐scale (>1000 km) domain in the first known experiment of this kind. With only a synoptic‐scale disturbance in the initial conditions, the model first develops a mesoscale convective system along a remnant frontal zone, which yields a mesoscale vortex. After a period of quiescence, banded convection organizes about the vortex from isolated, grid‐resolved cells, with the system becoming warm‐core and intensifying into Tropical Storm Diana.
