How is Scrooge described by Charles Dickens?

On Christmas Eve, densely foggy and bitterly cold. There is snow on the ground during his visitations. But Dickens describes Christmas morning as: "No fog, no mist; clear, bright, jovial, stirring, cold; cold, piping for the blood to dance to; Golden sun-light; Heavenly sky; sweet fresh air; merry bells. Oh, glorious! Glorious!"
