What is the climate type of Xichang?

Because Xichang has a relatively high altitude, it also has a relatively obvious plateau climate, but because of the influence of subtropical monsoon, the weather in Xichang is warmer and the temperature difference between morning and evening is relatively large. To put it bluntly, it is cold in the morning and evening, and it is very hot at noon. But the temperature will not be very high, and it will become very cold after two noon.
