concept

Understanding vectors, fields, and circulation

Weather apps show wind at every location: speed + direction. That's a vector (magnitude + direction).

Now they show this for EVERY point on the map. That's a vector field — a vector assigned to every location.

The visualization above does the same: each arrow shows the force/velocity at that point.
