A Tantalizing Question Regarding Climate

Usually, when we think about climate we think about stuff such as temperature, air pressure, rainfall, and so on. So, what would climate be like on another planet? I ask because I've been thinking recently about PH; acidic as opposed to basic (bases and acids). So, I decided to ask myself, what if we replaced temperature with PH? This could be a reality for climate on another planet, who knows? What would climate be like if it was a clash of PH instead of temperature? How would climate then behave? Does that make sense?
