Does the earth's rotation cause tailwinds, and how?

Hi lgr1-ga,

Good day and thanks for your question.

The Earth's rotation does play a role, but an indirect one. 

"The primary factor that affects the formation of winds is differences
in atmospheric pressure. As is true throughout nature, any fluid will
try to move from a region of high pressure to a region of low
pressure. The principal causes of these differences in pressure are
related to the absorption of heat due to solar radiation."
