Your experiment
Vertical: how long they stayed together. Horizontal: the initial difference. Hollow dots are wing flaps, which start somewhere else.
When the atmospheres split, how long they held together is logged here.
This is the convection model Edward Lorenz published in 1963. Each color is one atmosphere; stacked together they look white. If one wing were rain and the other sun, the counter would be the forecast: how many of the simulated atmospheres end up on each.
