What are the similarities and differences in climate between Changtan urban agglomeration in Hunan and Wuhan urban agglomeration in Hubei?

It should be Changsha-Zhuzhou-Xiangtan city circle and Wuhan 8+ 1 city circle. Because it is located near 30 degrees north latitude, it is affected by subtropical high in summer, and it is hot and rainy in summer. However, Hunan, close to Guangdong, is vulnerable to typhoons, which will cool most parts of Hunan, especially the south. On the other hand, Wuhan city circle is located in the plain, where the Yangtze River and the Han River meet, and the water vapor is strong and difficult to disperse, forming the so-called "sauna day". Damn weather. ~! It is cold and rainy in winter, but Hunan is mountainous. When the Asian high pressure raged, the cold air was blocked by mountains, so the temperature would not rise too fast, while in the Wuhan Plain, the cold air drove straight in and cooled down quickly ... It felt like high school again, hehe ~! I hope it helps you ~ ~!
