Scene notes:

Orographic effects on clouds can be varied. One tried and true method of identifying orographic clouds: do the clouds appear around the mountaintops and nowhere else? This affirmative can safely indicate an orographic effect: when the landscape influences the clouds directly. The sunrise requires no clouds at all to filter through at full radiant intensity. Slowly shifting clouds with little to no transformation over time can indicate very stable air. The mountain range brightens in the morning sun.
