Outline the development of amphidromic circulation in an ocean basin. What will be an ideal response?

---

cWater moving in a tide wave tends to stay to the right of an ocean basin due to the Coriolis
effect. As water moves north in a Northern Hemisphere ocean, it moves toward the eastern
boundary of the basin; as it moves south, it moves toward the western boundary. A wave
crest moving counterclockwise will develop around a node if this motion continues to be
stimulated by tidal forces. The node (or nodes) near the center of an ocean basin is called an
amphidromic point. An amphidromic point is a no-tide point in the ocean, around which the
tidal crest rotates through one tidal cycle. Amphidromic circulation develops as follows (in
the Northern Hemisphere): (1) A tide wave crest enters an ocean basin. (2) The wave trends
to the right, causing a high tide on the basin's eastern shore. (3) Unable to continue turning to
the right because of the interference of the shore, the crest moves northward, following the
shoreline and causing a high tide on the basin's northern shore. (4) The wave continues its
progress around the basin in a counterclockwise direction, forming a high tide on the western
shore and competing the circuit. The point around which the crest moves is an amphidromic
point.
