We call these tides neap tides, and it's when the difference between high and low tide is at its lowest.Ī neap tide happens between two spring tides, twice a month when the first and last quarter Moon appears. This means that the gravitational pull of the Moon and Sun actually work against each other. When we experience a low tide, the Moon is facing the Earth at a right angle to the Sun. These tide types occur twice every month. These are called the spring tide (also known as the King tide) and the neap tide. There are two types, or extremes, of the tide. Inertia wins, and this caused the ocean to bulge out and create a high tide.Īs the Earth spins, different locations on the planet will face the moon, and this rotation is what allows the tides to cycle around the planet. The water moving away from the moon is able to result the gravitational forces trying to pull it in the opposition direction because the gravitational pull is weaker on the far side of Earth. On the opposite side of Earth, the bulge is caused by inertia. The gravitational pull of the moon is strongest on whichever side of the Earth is facing it, annd gravity pulls the oceans towards the moon, resulting in a high tide. Tidal forces of the moon in the open ocean will form as bulges of water that face the moon, but around land mass and coast lines, the water is able to spread out onto land, which creates the tides.Įarth's tides change based on the gravitational pull of the moon as it orbits us. At the lowest point (also known as a trough) reaches the coast, we experience a low tide. When the highest point of the wave (also known as a crest) reaches a coastline, the coast experiences what we call a high tide. The tides are very long waves that move across our oceans, and they are caused by the gravitational pull from the moon and, to a lesser extent, the sun. (El Niño has the opposite effect in the Pacific, reducing the amount of wind shear.)Īt the same time, this year’s heightened sea surface temperatures pose a number of threats, including the ability to supercharge storms.The data and charts above provide the tide time predictions for Rehoboth Beach, Delaware for October 2023, with extra details provided for today, Tuesday October 10, 2023. Hurricanes need a calm environment to form, and the instability caused by increased wind shear makes those conditions less likely. In the Atlantic, El Niño increases the amount of wind shear, or the change in wind speed and direction from the ocean or land surface into the atmosphere. The intermittent climate phenomenon can have wide-ranging effects on weather around the world, and it typically impedes the formation of Atlantic hurricanes. This year features an El Niño pattern, which arrived in June. ( A record 30 named storms formed in 2020.) There were 14 named storms last year, after two extremely busy Atlantic hurricane seasons in which forecasters ran out of names and had to resort to backup lists. 10, NOAA officials revised their estimate upward, to 14 to 21 storms. In late May, the National Oceanic and Atmospheric Administration predicted that there would be 12 to 17 named storms this year, a “near-normal” amount. Lee is the 12th named storm to form in the Atlantic in 2023. Lee was a post-tropical cyclone in the Gulf of Saint Lawrence with sustained wind speeds of 45 miles per hour, the National Hurricane Center said in its latest advisory.
