My first guess would be that you have trusses rather than a cut
roof. Trusses are much more prone to this seasonal uplift. Only
you can decide what is the best cure. Latex painter's type caulk
is not good at stretching. There are caulks that are much better
about stretching, though you must be careful to avoid bonding to
anything more than 2 surfaces by using backer rod.

Here is some interesting reading on the problem:

anyone ever seen crown molding seperate from the ceiling?

it's all throughout the house, every room

1/4 - 3/8" long gaps...
the ceiling looks very flat

the gaps are at the top of the mldg, it seperates from the
ceiling, you
see the caulking
pulling here and there...the caulk does not stretch...

so it needs a caulk job, but I cannot imagine what is causing
this

during the summer there are no cracks
during the winter it looks awful

my guess is that the house shrinks during the winter
even the house has settle on one side leaving small
stress crack in an interior wall...

but this shrink swell winter summer mlding pulling loose

i have never seen this

it's all painted see...
