Middle-latitude cyclones in the Northern Hemisphere rotate counterclockwise due to the Coriolis effect. This is because winds deflect to the right in the Northern Hemisphere. Choice A is incorrect because middle-latitude cyclones have both warm and cold fronts. Choice B is incorrect because middle-latitude cyclones typically travel from west to east. Choice C is incorrect because middle-latitude cyclones are low-pressure systems, not high-pressure.
