Which of the following weather systems forms the crisp autumn weather in northern China?

The anticyclone has the highest air pressure at its center and gradually decreases outward, which is also called high air pressure. When the air in the anticyclone spreads around, it forms a downward airflow. Therefore, the weather in areas controlled by anticyclones is generally good.

I remember an example in the geography book. The crisp autumn weather in northern China is a special case of anticyclone.

The other three will form rainy weather.
