Hy,
sometimes I read that supercells are much more common in flat regions than in terrain with complex topography. Is that right? Can supercells interact destructively with complex underlying terrain? (large hilly or mountainous terrain, large Mountain ridges, etc...?) I know that under right Conditions supercells can also form in complex terrain. But is there a trend, that supercells are less common /weaker in complex terrain due to the complex wind shear or other effects?
