The surface pressure is 860 mb.  Storm speed is us = 1.5 m/s, vs = -5.5 m/s .

Convection is initiated by placing three positively buoyant thermals aligned NW to SE and spaced approximately 20 km apart, following these equations.
θ' = 0.5 Δθ (cos(πr) + 1)          for r < 1

r is the distance from (xr, yr, zr) where xr = yr = 10 km and zr = 1.5 km.  Δθ = 3 K.
