Concept:Tropical continental climate refers to the savanna/tropical wet-dry climate found in continental interiors near the tropics.
Explanation:This climate has a distinct alternation between a wet season and a dry season due to the seasonal movement of the Intertropical Convergence Zone (ITCZ).
Temperatures are high throughout the year, but they are not constant, and they show a notable diurnal (day and night) range.
Cloud cover changes between the seasons, so it is not absent throughout the year.
Thus, the distinguishing characteristic is the presence of alternating wet and dry seasons.
Answer:D. occurrence of alternating wet and dry seasons throughout the year
