"The weather conditions prevailing in an area in general or over a long period". The definition is written right there, as you summarized it so elegantly, AlwaysThere. Do you disregard that it states "in general or over a long period"? I mean you copied / pasted it right there. I'm not even mad, that's amazing you don't come away with the same conclusion as eric. He simply reiterated what you wrote, albeit in a more educated and refined manner in regards to the point being made. 

Still, the definition is right there and lays out exactly what climate is, yet you don't understand the definition it seems like.
