What is the direction of the largest mountain range in China? What is the wind direction of A, B, C and D? Characteristics of air pressure, temperature and precipitation in four places affected by the weather system According to the distribution of rivers in the picture, it can be inferred that the trend of mountains (basins) is east-west.

According to the isobar, the wind direction can be judged. A and B are northerly winds, and C and D are westerly winds.

The four places are located near the trough of low pressure, and A and B are located on one side of the cold air mass, with high air pressure, low temperature and rainy weather. Ding Bing is located on the side of the heating mass, with low air pressure, high temperature and sunny weather.
