Science / Tides and Currents / Radiational Tide: Periodic variations in sea level primarily related to meteorological changes such as the semi daily (solar) cycle in barometric pressure, daily (solar) land and sea breezes, and seasonal (annual) changes in temperature. Other changes in sea level due to meteorological changes that are random in phase are not considered radiational tides.
