← GeographyWhich outcome occurs regarding airflow in areas characterized by sharply contrasting surface temperatures?
A)Increased intensity of thermal circulation✓
B)Diminished cyclogenesis in midlatitudes
C)Weakening of the polar vortex system
D)Decreased frequency of Saharan dust plumes
💡 Explanation
Increased air temperature contrasts drive surface pressure differences, causing convective lifting and horizontal movements; thermal circulation intensity increases because temperature differentials amplify the pressure gradient differences; therefore, stronger circulation occurs, rather than weaker patterns.
