Not entirely sure I buy momentum as a first-order effect since blue thermals don't typically overrun the top of the invasion level by very much, so I can't imagine the top 2/3 of the thermal is simply momentum. Also, if it's thoroughly mixed from a temperature perspective wouldn't it also be mixed from a humidity perspective as well so it wouldn't be rising from having higher humidity either?

Curious.
