Pressure attraction

All right this may seem a bit odd but I’ve been wondering something. Let’s say you have a volume of gas. Inside the gas there are regions of high or low pressure. Is there a way to think about it where you might be able to think that regions of high or low pressure have either attraction or repulsion with each other? Hopefully someone kind of gets what I’m asking. Also, if so how would the attraction increase or decrease with seperation?
