What are the meteorological effects of a global nuclear war? Would the evening sky and dusk become blood red-colored and lasts longer than usual? Would the sun look different in the horizon? I know that the war could produce a "nuclear winter", but what happened before the global dimming? Would the temperature worldwide risen significantly before dropping to freeze?
Any info will be appreciated, since I need these for cinematic effects of a nuclear war.

Thanks in advance!
