Great PhD work by James Bassford in
@agu.org Geophys.Res.Lett.
Using statistical mechanics concepts he explains why one model can capture the bimodal water vapour distribution over tropical oceans, & another cannot
essopenarchive.org/users/593994...Tropical TCV as a process diagnostic: connecting probability to processes in km-scale models via moisture budget statistics
Observations show a bimodal frequency distribution in total column vapour (TCV) over tropical oceans, with convective rainfall predominantly produced on the moist side of the frequency minimum between...
