Why is the weather in Rushan so different from that in Weihai? Is the climate in Rushan the same as that in Qingdao? How to divide the climate in Weihai?

It's basically like this. For your reference, Weihai is located at the tip of the peninsula, and about three quarters of it is surrounded by the sea. There are seas in northwest, northeast and southeast. In winter, the northwest cold current and strong cold air push down without stopping, and it is easy to form snowfall when it meets the southeast warm current. Rushan, on the other hand, is located on the south coast of the peninsula, surrounded by the southern bay, and the hills and mountains in the northwest block the cold current with little influence. Rushan and Qingdao are close in climate because they are located on the southern coast of the peninsula, but Qingdao is closer to the semi-circular bay, which has a greater impact on the ocean airflow, so it is warm in winter and cool in summer, and the climate is better.
