text: At the wingtip these disparate pressures meet in the form of a vortex as the high pressure flow around the wingtip is sucked into the low pressure above the wing; the greater the pressure differences (such as in the case in slower flight), the greater the vortices are at each wing tip, and the greater the drag caused by these vortices.1
