“…The stronger sea-breeze circulation and deeper inflow layer are due to the higher air temperature in the urban area. This is consistent with the results of previous studies (e.g., Yoshikado 1992;Fock and Schl€ unzen 2012). Figure 11 shows the vertical cross sections of potential temperature, vertical velocity, and wind along the line E-F in the URBAN and NO-URBAN simulations.…”

Daytime local circulations and their interactions in the Seoul, South Korea, metropolitan area are investigated using a high-resolution mesoscale model. It is found that the urban-breeze circulation interacts strongly with other local circulations, such as sea-breeze, cross-valley, and river-breeze circulations. Inland penetration of the sea breeze is retarded in the morning when moving over the coastal urban area because of the increased surface roughness but is accelerated in the afternoon after passing through the urban area as a result of the landward-convergent flow induced by urban heat islands in the inland urban areas. In the valley region, the cross-valley circulation prevails in the morning and the urban-breeze circulation prevails in the afternoon. The mountainside urban-breeze circulation weakens because of the cross-valley circulation in the opposite direction. On the other hand, the plainside urban-breeze circulation away from the mountain increases in strength as a result of the combined effect of heating from the urban surface and subsidence heating associated with the cross-valley circulation. This strengthened urban breeze acts to inhibit penetration of the sea breeze farther inland, causing the sea breeze to stagnate in Seoul. In the vicinity of the Han River, convergence zones with strong updrafts are formed as a result of the interaction between the urban breeze and the river breeze. When the sea-breeze front encounters the strong updrafts, the vertical velocity of the front at the intersection points increases.

A simulation with the Méso-NH model over the island of Mallorca, Spain, has been made in a case of synoptic high pressure (5 June 2010) that allowed the development of sea breezes (SB) in the three main basins of the island. The results compare well to the available observations and are qualitatively very close to a previous idealized study with no synoptic forcing made by Ramis and Romero in 1995. The temporal and spatial structure of the SB in the southeastern basin is analyzed with the use of the momentum, temperature, and turbulence kinetic energy budgets provided by the numerical model. Five stages of evolution from before dawn to after sunset are discussed, identifying the main physical mechanisms at play. The morning land heating warms the land and the air over it until an air temperature gradient is created and a marine flow accelerates inland, dragged by turbulence in the low layers. The upper part of the inland current and the layers just above are dominated by compensatory motions, which oppose the corresponding pressure gradient at these levels. These mechanisms last while the SB is active, with significant effects from the local topography, and they decrease in intensity as sunset approaches. This relatively simple case has been used to check the goodness of two analytical models of the SB that perform relatively well because they use turbulence as a surrogate for the missing advection terms in the layers above 200 m. These models are formulated here in a more consistent manner in the turbulence parameterization than were the original propositions.
