What can you tell me about tidal movements and currents off the coast of Copenhagen, Denmark?
<|assistant|>
The waters around Copenhagen, Denmark experience two primary tidal movements: a daily cycle and an annual cycle. On an hourly basis, the most prominent features of the daily tidal cycle are the semi-diurnal and diurnal cycles, which are caused by the gravitational interaction between the moon and the Earth. On an annual level, the greatest changes in the flow of the water are due to the astronomical cycle of the sun, which dictates how the oceans heat and cool throughout the year. Off the coast of Copenhagen, the strong Kattegat Current is the primary driver of the region’s water flow, leading to swift and cold waters.
