shape of thermals

have you wondered what shape a thermal has? a bubble? a cylinder?

i found an article in a model airplane's magazine (american modeler-august 1961-page 42), where the author (Bill Winter) provides a link on the thermals shape and behaviour, from an article from Soaring magazine, by Clarence Cone, issues april/may/june 1961.
this is the link: page 8

the link was lost, but managed to retrieve it.
