英文摘要 | It has been speculated that the spume droplets torn off from ocean waves in high wind speeds (larger than about 9ms(-1)) enhance air-sea fluxes. However, the vertical transport of spume droplets in the high-wind atmospheric boundary layer (ABL) is little researched and lacks the support of numerical simulations. Based on observational data and the characteristics of high-wind ABL above the ocean, the vertical transport of spume droplets is studied and simulated. It is revealed that the existence of gusty wind with coherent structure during high winds is favorable for the vertical transport of the large-size droplets. The trajectories of 1000 spume droplets with different sizes under different wind speeds in the range 10-35ms(-1) are calculated, and the uplifting fraction of spume droplets that can reach the 100m height in the ABL is parameterized by using a nondimensional factor U-10(2)/(r(80)g), where U-10 is the wind speed at 10m height, r(80) the equilibrium radius of droplet at an equivalent 80% relative humidity, and g the gravitational acceleration. Then, the upward flux of large-size spume droplets and the mass concentration at 100m height are evaluated. These numerical results are comparable to some observational data and show that the large-size spume droplets can be entrained into the ABL during high winds and then contribute to the air-sea mass fluxes. |
