You wont see the ccw pattern being flown more than cw pattern around these parts...being in the Northern hemisphere practically all runways are laid out with the pilot stations south or southwest through southeast to the runways...simply to avoid flying with the sun in your eyes. The runways are predominately east/ westish with variations all the way to North. The prevailing winds are westerly so the majoriy of the time the pattern is cw to avoid landind with a tailwind. If the wind is CALM then i see the pattern reversed because guys are bored with the standard cw pattern and enjoy flying a different approach. Now if the only time you go to the field is on a CALM day then perhaps you might notice more ccw patterns.
