For an ongoing research project, I have been doing some reading on the history of Chinese medicine as it relates to the weather. Reading the Inner Canon of the Yellow Emperor, I came across these striking analogies measuring out the human pulse through the movement of wind:

When the heart pulse beats vigorously and the strokes are markedly prolonged, the corresponding illness makes the tongue curl up and makes to patient unable to speak. When the pulse beats are soft and scattered like willow blossoms scattering with the wind, it is fitting that one diffuse the encirclement of the corresponding illness.
When the pulse is tardy like willow branches swaying to a light breeze, and slippery, like pebbles rolling in a basin, it means that there are fevers raging within the body.
