Does crisp autumn describe weather or climate?

Crisp autumn means clear skies and crisp weather in Wan Li, and describes the weather.

In addition, the autumn sky is not as gray as winter and spring, nor does it cover the sun with dark clouds like summer. The sky is blue, with a few white clouds floating occasionally. The temperature is neither too hot nor too cold, which is very pleasant. Therefore, people often praise it as "crisp autumn", which in turn means describing the climate.

I think crisp autumn is a description of the weather and climate. It contains two meanings. The emphasis is on describing the climate.
