Why is Shiyan hotter than Wuhan?

The main reasons why Shiyan is hotter than Wuhan are as follows:

1. Shiyan is located in the hinterland of Qinba Mountain. It is difficult for winds from the mainland or northwest to circulate here, and they are basically blocked by mountains.

2. The water in Danjiangkou Reservoir in Shiyan evaporates and dissipates too much heat during the day in summer, resulting in a higher temperature here.

3. There is little precipitation in Shiyan, which can reduce the humidity in the air and make the weather hotter.

The above are only general reasons, and the specific situation may change due to different factors.
