The cloud water (red contours), precipitating water (blue
shades) and relative wind (arrows) of the propagating convective cell
are shown as a snap shot at 1 hour 25 min. after the initiation of the
first cell at x=0 for the two case in which the domain limits are placed
differently: (a) the cell is just crossing the interface at x=48 km,
between the domains of 1 km and 2 km resolution; and (b) the cell is
still inside the domain of 1 km resolution that extends to x=72 km. The
two cases will not produce exactly the same result, but their similarity
demonstrates the working of the new nesting algorithm.
