Influence of the wind waves dissipation processes on dynamics in the water upper layer amg

Stoc­has­tic surface wind waves are cons­ide­red as an inte­rmed­iate phys­ical phen­ome­non resp­onsi­ble for the state of upper layer of the water column. Math­emat­ical form­ulat­ion of the problem is done by using the wind wave spec­tral evol­ution model. It is shown that para­met­ers of the air boun­dary layer are cont­rol­led by input evol­ution mech­anism of wind waves, while diss­ipat­ion mech­anism is impo­rtant for desc­ript­ion of energy and mome­ntum tran­sfer into upper layer of the water column. Esti­mati­ons of the wave energy diss­ipat­ion rate are found util­izing the opti­mized nume­rical model for wind waves derived earlier. Such esti­mati­ons can be used for better desc­ript­ion of nume­rous impo­rtant phen­omena at the air–sea surface, incl­uding air bubbles entr­ainm­ent, vert­ical mixing of oil slicks, near surface shear flow and many others. Three appl­icat­ions of the theory are pres­ented
