Thy hair soft-lifted by the winnowing wind - antistrophe
Autumn is a woman- seasons were traditionally personified as female in European art
The word "winnowing" is perfect here because "to winnow" in farm-speak means to separate the grain (the edible part of the plant) from the chaff (its inedible covering). In centuries past, farmers winnowed their crops by having people beat the harvested plant with, say, large sticks. This action loosens the heavier grain, and then the chaff is light enough that it can be blown away, or "winnowed," in the wind.
The place where the grain and the chaff are separated is called the "threshing floor" - this is where autumn is
