This was a great explanation of drift. Other observations I would add are that you get more drift the colder it is, and the less humid the air. Colder air is more dense, and dry air is (counterintuitively) more dense than humid air. The more dense the air the greater the effect and force on the ball. So I notice it much more at the end of evening nets when it is cloudy.Physics ATAR and dash of boredom
I also find cross wind helps a lot.
Dip is a funny one because as a bowler it is much harder to pick up how much actually you are getting the ball to dip, but the books and coaching manuals constantly talk about how fundamental it is.
