I was reading another weather prediction which again failed miserably to predict the weather. In the graphic illustration in the prediction it showed both a low pressure system (counter clockwise rotation) and a high pressure system (clockwise rotation), both systems in the the northern hemisphere with the low pressure system following the high pressure system. And I wondereded how, considering the corolla effect in the nothern hemisphere, causing storms to spin counter clockwise, how high pressure systems can spin clockwise against the corolla forces?
