This community's purpose is to teach about water vapour interpretation and potential vorticity assessment.  In the mid-latitudes, it is possible to evaluate NWP initialization using satellite WV observations and PV output from NWP models.  Within this community there are resources to help you understand WV and PV interpretation as well as a forum to discuss further concerns about these two topics, plus their synergy in the NWP assessment field.
