Anticyclonic rotation
Anticyclonic rotation or circulation is movement in the direction opposite to the Earth's rotation. In the attached video an example of an anticyclonic couplet to a supercell is documented. Note that while the supercell itself is rotating in a cyclonic direction, the couplet is forced into an anticyclonic rotation due to the forward flank downdraft and inflow intersecting. Anticyclones on the synoptic scale are more often associated with higher pressure in relation to low pressure cyclones.
