| definition | A quasi-periodic rise and fall of sea level caused by meteorological variability, hence also known as “meteorological tides”. Semi-diurnal radiational tides in the tropics are thought to be due to semi-diurnal fluctuations in surface barometric pressure forced at diurnal period at the top of the atmosphere (sometimes called "atmospheric tide"). Diurnal radiational tides are often caused by land/sea breezes or solar heating (note that neither of these forcing functions are purely sinusoidal in time). Monsoonal winds may cause semiannual radiational tides on some coastlines. Annual heating of the atmosphere and redistribution of air mass can both cause annual radiational tides. | ||||||
