The weather system shown in the picture often appears in winter in Yunnan-Guizhou Plateau. Read the pictures and complete questions 26-27. About the causes of the weather in Kunming and Guiyang, the correct statement is A, Kunming is cool in summer mainly because of its high altitude and cool climate, which does not meet the meaning of the question;

B. According to the analysis of the frontal symbol diagram in Figure A, Kunming is on the side of the warm air mass and Guiyang is on the side of the cold air mass, so Kunming is warmer than Guiyang in winter, so it is correct;

C. According to the analysis of the frontal symbol diagram in Figure A, Kunming is on the side of the warm air mass and Guiyang is on the side of the cold air mass. Therefore, Guiyang has a rainy front in winter and a cold climate, which does not meet the meaning of the question;

D. According to the meaning of the problem, there is a quasi-static front between Kunming and Guiyang, and continuous rainy weather occurs when the front crosses the border. According to the analysis of the frontal symbol diagram in Figure A, Kunming is on the side of the warm air mass and Guiyang is on the side of the cold air mass, so there is a lot of frontal rainfall in Guiyang in winter.
