Minecraft wiki entry for Coordinates, associated text: Like relative coordinates, these describe positions relative to where a command is executed from, but with different directions. A number following a caret (^) is an offset within a moving, entity-centric frame: This coordinate system is centered at the executor's position, with +Xlocal directed to its left, +Ylocal directed upward, and +Zlocal directed in the direction the sender faces. (Note that an entity with rotation 0 0 has its local frame aligned with the world frame.)
