Nice overlay but that's a false-colour infra-red satellite picture rather than a radar plot. The satellite picture will tell you the temperature of the cloud tops, which corresponds roughly to their altitude but it won’t show areas of precipitation or strong air movement.
The area where the Air Asia went down, purely looking at that picture, could be an active cell going from 1,000’ up towards the tropopause or it could be the remains of an old CB anvil/blow-off at 45,000' with nothing underneath. Given the gyrations of the aircraft, it’s probably going to turn out to be the former but you couldn’t say from that picture.
