Why is it warm and sunny in winter in Jinan?

This is the characteristic of Jinan's climate.

Spring and autumn in Jinan are very short.

It's autumn now, but the temperature in Jinan is sometimes very high, and there is no shadow of autumn at all. /kloc-it's sunny in October. 1 1 The temperature may suddenly enter the feeling of winter. In fact, you can feel autumn in a few days, so some of my clothes in spring and autumn are sometimes too hot or too cold to wear. The warm and sunny weather in Jinan can account for half of the whole year. It is usually warm from May to 65438+ 10, so I really want to experience the feeling of winter now, because "summer" is too long, and I forgot the feeling of cold in winter.
