Question

Quizplus · Accepted Answer

Semipermanent high and low pressure cells undergo seasonal changes in position and intensity over the course of a year. This is due to changes in global atmospheric circulation patterns and the distribution of energy from the sun. However, they do not disappear completely and are always present to some degree in their respective regions. Therefore, choices A and B are incorrect. Choice D is also incorrect because semipermanent pressure cells undergo both changes in intensity and position over the course of a year.
