With different land-use characteristics (e.g., moist irrigated fields Inland sea breezes form along boundaries between adjacent land regions Similar flows called lake breezes form along lake shorelines, and ![]() It occurs in large-scale high-pressure regions of weak or calm synoptic-scale wind under mostly clear skies. Sea breezes, land breezes, katabatic winds, and coastal (barrier) jets.Ī sea breeze is a shallow cool wind that blows onshore (from sea to land) during daytime (see figure below).

For offshore flows, the tidal effect on wind-speed profiles is examined, with results showing that the tide state influences the time at which the sea-breeze speed increases but not the daily maximum speed of the sea breeze.Īrritt RW (1989) Numerical modeling of the offshore extent of sea breezes. This could be explained by the shorter distance to the sea due to the movement of the water boundary towards the station as well as larger sea–land temperature difference during high tide. The results indicate that there is a significant difference due to tidal state in the onset time of the sea breeze only for offshore flow, showing earlier arrival for the high-tide group in the morning than the low-tide group in the morning. The tidal effect on the sea breeze is tested at a significance level of 5% using a two-sample t-test for onshore and offshore flows. Sea-breeze days are divided into four groups depending on the tidal state and ambient flow direction. A sea-breeze day is defined as a day with both onset and cessation of a sea breeze within 24 h. We consider sea-breeze days during the warm season from May to September of each year from 2014 to 2017. The tidal effect on a sea breeze is examined using a 4-year 30-min database of wind-speed profiles obtained from a 300-m tower at a coastal site in Boseong, South Korea, facing a bay with tidal flats.
