Hello I am looking for a map that shows the typical (typical for the last 50 years) precipitation paths in the Northern Hemisphere! I already know this map, but it only shows a momentary event and does not help me any further.
EDIT: EG. I mean typical rain paths, such as the water masses for Europe evaporating in the Central Atlantic and then being "pushed" towards Europe between the Azores high and the Icelandic low.
