co-tidal

A co-tidal line connects points where high tide occurs at the same time.

Definition

1. Adjective:
   • Relating to simultaneous tides: "co-tidal" describes points or lines on a map where high tide occurs at the same time. It is used in geography and oceanography to study tidal patterns.
   • Of a line connecting equal tidal times: Specifically, a "co-tidal line" connects locations that experience high tide simultaneously.

Usage Examples

• Adjective:
  • The co-tidal lines on the chart showed that the tide rises at the same hour along the entire coast. (Lines connecting places with simultaneous high tides.)
  • Researchers plotted co-tidal points to understand the tidal wave propagation in the bay. (Points where high tide occurs at the same moment.)

Advanced Usage

• "co-tidal line": a line on a map joining points that have high tide at the same time.

  • Navigators use co-tidal lines to predict tidal heights for safe passage. (These lines help determine when high water will occur.)

• "co-tidal chart": a map that displays co-tidal lines and tidal ranges.

  • The co-tidal chart for the North Sea is essential for marine planning. (The chart shows simultaneous tidal timings.)

Variants and Related Words

• Co-tidal (n): a line or point of simultaneous high tide (used as a noun in technical contexts).

  • The co-tidal for this region is marked by a dashed curve. (The line indicating equal tidal times.)

• Tidal (adj): relating to tides.

  • Tidal forces are caused by the moon's gravity. (Forces associated with ocean tides.)

Synonyms

• Isotidal: another term for "co-tidal," meaning equal tidal times.
• Synchronous tidal: describing tides that occur at the same time.

Additional Notes

• The prefix "co-" means "together" or "equal," and "tidal" refers to tides. Thus, "co-tidal" literally means "together with the tide" in timing.
