Explaining coriolis when the relevant pressure systems are at the same latitude
I've been asked (another) awkward question during a groundschool session. I started to answer but then confessed that I was in danger of waffling so would stop and report back later with the answer. Fundamentally the question was that the Coriolis effect/force is easy to understand when the H/L pressure systems are at different latitudes, but what happens when they are on the same latitude?
