A tropical sea-breeze circulation is simulated by using a two-dimensional mesoscale primitive equations model. The numerical experiments are carried out for a special case during winter under the typical prevailing trade wind regime over northern Queensland. Particular attention is paid to the behaviour of the onshore flow component, which occurs over the nearshore sea surface at night, and the corresponding sea-breeze circulation offshore. The interaction between a land breeze and the onshore wind component is discussed in the case where the land breeze lies at the coast rather than penetrates out to sea. The effects of local terrain (a hill), an island and large-scale wind on the sea-land breeze circulation are also investigated.
