The cabinet principle
Weather enters the collection when it is found somewhere it should not be and remains there long enough to receive a label.
The Grand Cabinet is arranged by misplacement rather than meteorology. A shower beneath a dining table belongs to Department I even if its cloud remains outdoors. Fog in a locked drawer belongs to Department II until ownership is established, at which point it may move to III.
Every transfer is witnessed by a curator, a conservator, and whichever instrument first admits the phenomenon is real.

Rain found indoors
Table showers, cupboard drizzle, stairwell monsoons, and rain remembered by carpets.

Wind in sealed drawers
Drafts discovered after keys, socks, or documents have moved independently.

Privately owned fog
Inherited mists, family haze, and vapor accompanied by proof of purchase.

Warm corners
Architectural heat without pipes, sun, occupants, or reasonable enthusiasm.

Hail of uncertain scale
Stones described as pea-, marble-, teacup-, and emotionally large.

Unclaimed rainbows
Color arcs found without rain, owner, pot, or complete violet.

Administrative frost
Ice formed on forms, seals, desks, and pending decisions.

Sunshine (copies)
Reproductions retained where original brightness cannot be safely lent.
