cotidal line मीनिंग इन हिंदी

उदाहरण वाक्य

1. South of Cape Hatteras the tidal forces are more complex, and cannot be predicted reliably based on the North Atlantic cotidal lines.
2. High water rotates about the amphidromic point once every 12 hours in the direction of rising cotidal lines, and away from ebbing cotidal lines.
3. High water rotates about the amphidromic point once every 12 hours in the direction of rising cotidal lines, and away from ebbing cotidal lines.
4. This is because cotidal lines 180?around the amphidromes are in opposite phase, for example high water across from low water at each end of Cook Strait.
5. In the North Atlantic, because the cotidal lines circulate counterclockwise around the amphidromic point, the high tide passes New York Harbor approximately an hour ahead of Norfolk Harbor.
6. In the " M " 2 plot above, each cotidal line differs by one hour from its neighbors, and the thicker lines show tides in phase with equilibrium at Greenwich.
7. For an ocean in the shape of a circular basin enclosed by a coastline, the " cotidal lines " point radially inward and must eventually meet at a common point, the amphidromic point.
8. For a semi-diurnal tide the amphidromic point can be thought of roughly like the center of a clock face, with the hour hand pointing in the direction of the high water cotidal line, which is directly opposite the low water cotidal line.
9. For a semi-diurnal tide the amphidromic point can be thought of roughly like the center of a clock face, with the hour hand pointing in the direction of the high water cotidal line, which is directly opposite the low water cotidal line.
10. The amphidromic point is at once cotidal with high and low waters, which is satisfied by " zero " tidal motion . ( The rare exception occurs when the tide encircles an island, as it does around New Zealand, Iceland and Madagascar . ) Tidal motion generally lessens moving away from continental coasts, so that crossing the cotidal lines are contours of constant " amplitude " ( half the distance between high and low water ) which decrease to zero at the amphidromic point.
