Here and There: Points and Vectors in 2D

In 1992 Hurricane Andrew hit the northwestern Bahamas, south Florida, and south-central Louisiana with such great force that it is rated as the most expensive hurricane to date, causing more than $25 billion of damage. ¹ In the hurricane image (Figure 2.1) air is moving rapidly, spiraling in a counterclockwise fashion. What isn’t so clear from this image is that the air moves faster as it approaches the eye of the hurricane. This air 14movement is best described by points and vectors: at any location (point), air moves in a certain direction and with a certain speed (velocity vector).
