Hi all does anyone know the reason why pressure charts are presented as they are? I can't be the only one to find it confusing when something looks like it's going north east when in fact it's just going east.
I can only assume there's a reason in there somewhere but seeing the ones that Simon uses which center on the pole I feel they are much clearer than the standard ones.

???? Pressure charts show isobars which are lines connecting points of same pressure. What's your problem?

All representations of parts of a sphere (or oblate spheroid for the pedants) in 2-dimensions have to be distorted. Which projection would you prefer? Mercator might suit your prejudices.
The one that really annoys me is the Beeb weather map of the UK which seems to be drawn with the perspective as if seen from the top of the Eiffel Tower.
