National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Thermal and Size Evolution of Sea Spray Droplets.

ADA210484

Publication Date	1989
Personal Author	Andreas, E. L.
Page Count	47
Abstract	Sea spray droplets initially have the same temperature as the ocean surface from which they formed. In high latitudes, under a relatively cold wind, they therefore cool and evaporate, in effect enhancing the air-sea exchange of heat and moisture. With a future goal of investigating this enhanced exchange in mind, this report develops model equations with which to track the thermal and size (moisture content) evolution of a spray droplet from the time it is created until it comes to equilibrium with its environment. On testing the model against some of the scanty data available on the evolution of saline droplets, good agreement is found. The ambient humidity has little effect on the thermal exchange, and, analogously, the initial droplet temperature has negligible effect on the moisture exchange. Keywords: Air-sea interaction; Bubbles; Heat transfer; Microphysics; Moisture transfer; Polar lows temperature; Sea spray; Water droplets; Whitecaps. (KT)
