What does late autumn mean?

The "deep" in late autumn means: the end. Late autumn is the name of this season. Generally speaking, late October is called late autumn. The temperature drops sharply in late autumn, which is not far from winter. Most of the crops have been harvested, and this is a truly desolate world.

Example:

1. In the late autumn morning, endless white fog enveloped the earth.

2. Leaves are butterflies that have not been taken away in late autumn. Are they brewing one last time?
