tide, salt water, opportunity
潮 centers on the rhythmic movement of the sea: the tide. Salt water is the substance of that tide, and opportunity is a natural extension—like a favorable tide that comes and goes.
潮 combines 氵 (water) with 朝, which likely contributes the sound and the idea of morning, when tides are often observed. The character expresses the tide and its associated salt water.
Water 氵 and morning 朝 come together: picture the morning tide rolling in, bringing salt water and new opportunities with the waves.
For チョウ, imagine a tide so strong it makes a distinctive 'chow' sound as it crashes: chow -> チョウ, and the morning tide brings the sea's rhythm.
