A spring tide—popularly known as a "King Tide"—refers to the 'springing forth' of the tide during new and full moon. A neap tide —seven days after a spring tide—refers to a period of moderate tides when the sun and moon are at right angles to each other.
What is a neap tide? When the sun and moons are at right angles to each other, there is least gravitational pull, meaning the tidal range is at its lowest. The neap tide occurs 7 days after the spring tide.
5 Αυγ 2021 · When the Sun is at a right angle to the Moon, moderate tides, called neap tides, result. From our view on Earth, these tides coincide with certain lunar phases since they occur when the Moon reaches specific positions in its orbit. Earth’s tidal bulges don’t line up exactly with the Moon’s position.
20 Δεκ 2021 · When the solar and lunar tides are 90° out of phase, their effects cancel each other (first and last quarter). The ellipsoid approaches a circle, and consequently the tide gets a smaller amplitude. This situation is called neap tide (Fig. 3.21).
Neap tides are a type of tidal pattern that occurs twice a month, during the first and third quarters of the moon. During neap tides, the difference between high and low tide is at its minimum. This phenomenon happens due to the gravitational pull of the sun and the moon on the Earth’s oceans.
Definition. A neap tide is a type of tide that occurs when the difference between high and low tides is at its smallest, typically occurring during the first and third quarters of the moon. This phenomenon arises because the gravitational forces of the moon and the sun are perpendicular to each other, which results in lower tidal ranges.
