<br>Scroll down a bit till you'll see the three drawings with alot of arrows. The black vertical arrow in each drawing is the wind the other black arrow is the airflow caused by the forward movement of the craft and the resulting blue arrow is the apparent wind.

<br>Hope this visualizes things and thus help your understanding
