Astronomy Tower

[Kaitlin]

Is it the same conditions as outside, or do the maintenance 
people/elves decide what weather the ceiling should have?  If you 
remember from when Arthur takes Harry to his office before the hearing 
(OoTP), Harry notes that Arthur has windows even though he's 
underground.  Arthur tells him that magical maintenance decides what 
kind of weather they should have each day, and that they once had two 
weeks of hurricaines when maintenance was fighting for a pay raise.  
I wonder if this is the same kind of thing?
Cheers!
