clear sky thermals-or lift


clear sky thermals
i have had my planes into thermals many times, be free flight towline gliders or rubber or engine powered, or r/c sailplanes.
so far i am under the impression that thermals rise from the ground in the shape of bubbles, although i could buy the idea that there are also columns. these bubbles or columns reach the level of condensation and form clouds. i have seen my planes reaching a cloud and being swallowed, so i believe this.
but what about a plane climbing into clear air? no clouds in sight?
this happens to me some times.
is there a source where we can learn about this?
meteorological data?
please bring any info here.
thanks
