Poetic geography describing the weather

Quoted from Bai Xuege's Farewell to Tian Wu's Home by a poet in the prosperous Tang Dynasty.

The north wind swept across the earth, breaking hundreds of herbs, and the weather in Alakazam began to snow in August. Suddenly, it was like a spring breeze blowing overnight, as if thousands of trees and pears were in full bloom.

The north wind described is northwest wind, not spring breeze.
