Castellanus

Turbulent mixing, evidenced by alto-cumulus castellanus cloud over France, also took place en route and carried dust to high altitudes.

Over France the altocumuli castellani clouds at medium level indicate a very unstable air mass there, because these clouds often develop into thunderstorms.

But liftoff in warm, moist, unstable air in which condensation is occurring may result in an updraft capped by a towering altocumulus castellanus cloud at 11,000 to 15,000 feet.

When a layer of cloud rises in distinct turrets with bumpy tops that resemble crenellations, it is of the species known as castellanus—and this one can give an early indication of unsettled weather to come later in the day.

In addition to the rettori, there were castellani of the fort in the town of Chios and of fourteen other forts in the society's island. The castellanus of the urban fort was chosen by a complicated process of indirect election resembling that which determined the Podestà, and again like him was to be drawn from the popolari of Genoa.

Castle garrisons are castellani; WP does not use the term oppidani.

In these documents conderning the castle of Talarn, however, the term castellanus is applied to both of the bottom two levels of the hierarchy: the texts imply that both Oliver Bernat and Guillem Folc are castellani.
