Not sure if there’s some other reason, but in the stratosphere you don’t afaik* get big convective updrafts like there are in the troposphere, which I presume is due to the rate at which temperature declines with altitude getting smaller than the rate at which a rising air body will cool due to expansion.
*Actually I think that this property is basically what defines the stratosphere vs the troposphere?
