How would you adjust past analogs toward today's climate?
Some options come to top of mind:
- brute force of adjusting temps up by a couple degrees across the board (oversimplistic, but can be complicated by the fact that doing so would eliminate 32-33 degree snowstorms we had in the past, esp in the MA)
- adjusting storm tracks northward. Example: 72-73 had that big storm and much above normal snowfall across the SE US, but virtually nothing from DC to NYC. What if a 72-73 happened today? Would that storm have traversed further north and resulted in a DC-NYC hit?
- match every winter from 2000 to today with the best pre-1980 analog, and compare the forcing (location and intensity), and note the changes as a result of a warmer state?
