In the following weather system, can say "summer drought" weather is ().

D analysis: The four pictures are commonly used in weather systems. Both A and B are frontal system diagrams, and both are cold under and warm up. Cold and warm fronts can be distinguished by the arrows of cold air masses or by the characteristics of cloud systems. The horizontal cold air mass is a cold front and the local circulation is a warm front, so A is a cold front and B is a warm front system. C and D are barometric systems, where updraft prevails in center C, leading to low near-surface pressure and rainy weather, and downdraft prevails in center D, leading to high pressure and sunny and dry near-surface weather, while dry weather in summer is formed as a weather feature controlled by high pressure, so D is correct. Test center: check the common weather system and map reading and analysis ability.
