Impacto do Efeito da Quebra de Ondas Oce\u00e2nicas na Estrutura da Camada Limite Atmosf\u00e9rica.<\/strong><\/h3>\n
Neste trabalho foi constru\u00eddo um modelo num\u00e9rico unidimensional de Camada Limite Planet\u00e1ria (CLP), com a Camada de Limite Superficial\u00a0 segundo a teoria de similaridade e os coeficientes de difusividade extrapolados ate o topo da CLP. Os processos f\u00edsicos do arrasto das ondas e da produ\u00e7\u00e3o de got\u00edculas na atmosfera foram implementados no modelo com o intuito de compreender e avaliar seus efeitos (transporte de momentum e calor) na estrutura da CLP.<\/div>\n

The Impact of Spume Droplets and Wave Stress Parametrizations on Simulated Near-Surface Maritime Wind and Temperature.<\/strong><\/h3>\n
The influence of ocean gravity waves on the wind and temperature above the surface is investigated using a one-dimensional boundary layer model. The effect of the wave-induced stress is evaluated using three parameterizations: wave age (WaAg), wave steepness (WaSt), and wind action on the wave spectrum (WiAc). It is found that while the WaAg is more effective in reducing the wind for young waves, in the WaSt approach the maximum reduction is for old waves. On the other hand, the WiAc is very sensitive to the energy present in high frequencies corresponding to periods less than 2 s, which are found in both young and mature spectra. Since observations show that most of the wave stress is due to the small-period wave energy, in this aspect the WaSt parameterization is not recommended; WaAg is not as accurate; and thus WiAc is the best among the three, although its computational cost is the highest.<\/div>\n

Analytical Quantification of Carbon Dioxide Exchange Mediated by Spume Droplets<\/strong><\/h3>\n
The role of spume droplets in the air\u2013sea exchange of CO<\/span><\/span><\/span>2<\/span><\/span><\/span><\/span><\/span><\/span><\/span> is investigated by applying simultaneous rate equations for the mass of dissolved CO<\/span><\/span><\/span>2<\/span><\/span><\/span><\/span><\/span><\/span><\/span>, radius, and temperature of a droplet. The life of a droplet can be divided into two phases, except when the air is saturated, and when the air and sea temperatures are the same. In the first phase, the CO<\/span><\/span><\/span>2<\/span><\/span><\/span><\/span><\/span><\/span><\/span> fluxes at the droplet surface and at the air\u2013sea interface are in the same direction. In the second phase, the air\u2013droplet CO<\/span><\/span><\/span>2<\/span><\/span><\/span><\/span><\/span><\/span><\/span> gradient vanishes, and the droplet loses water and CO<\/span><\/span><\/span>2<\/span><\/span><\/span><\/span><\/span><\/span><\/span> as long as there is evaporation. The largest sea\u2013air CO<\/span><\/span><\/span>2<\/span><\/span><\/span><\/span><\/span><\/span><\/span> transfer by the droplets is in the case where the sea temperature is greater than the air temperature, and the air\u2013sea CO<\/span><\/span><\/span>2<\/span><\/span><\/span><\/span><\/span><\/span><\/span> concentration gradient is towards the air. The net transfer of CO<\/span><\/span><\/span>2<\/span><\/span><\/span><\/span><\/span><\/span><\/span> for a droplet depends on its lifetime, which is longer for smaller droplets. The overall role of a droplet spectrum is assessed assuming a sea-spray generation function for radii from 30 to 500\u00a0\u03bc<\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/span>m, whose formulation of its dependence on the surface-wave peak period and 10-m wind speed is currently accepted; for situations with an air\u2013sea CO<\/span><\/span><\/span>2<\/span><\/span><\/span><\/span><\/span><\/span><\/span> concentration gradient towards the air and a warmer sea than the air, the overall transfer obtained is towards the sea. The effect of the turbulence is analyzed by increasing the droplet lifetime by a factor of 10, which increases the CO<\/span><\/span><\/span>2<\/span><\/span><\/span><\/span><\/span><\/span><\/span> flux towards the sea for droplet spectra composed mainly of small droplets (generated by waves with small peak period). However, the mean droplet size is larger for droplets generated by waves with a high peak period, and then the flux is towards the air because many large droplets reach the second phase.
