Solar heating in the upper ocean
- Univ. of Alaska, Fairbanks, AK (United States)
A discrete ordinate method has been developed to solve the radiative transfer problem in nonuniformly refracting layered media such as the atmosphere-ocean system. In the radiative transfer model for the atmosphere-ocean system the essential points are: In the ocean, region I is the total reflection region and region II is the refraction region. The downward radiation distributed over 2{pi} steradians in the atmosphere is restricted to a cone (less than 27{pi} steradians) upon refraction across the interface into the ocean. Photons in region 11 of the ocean may be scattered into region 1. Note, however, that photons in region I of the ocean cannot reach the atmosphere directly and vice versa. The atmosphere and region I {open_quotes}communicate{close_quotes} through the scattering process between region I and region II in the ocean. Appropriate quadrature points (streams) and weights have been chosen for the interface continuity relations. To take into account the region of total reflection in the ocean, separate angular quadrature points are adopted in addition to those used in the atmosphere and the refractive region of the sea ice and ocean. This quadrature specification automatically accounts for the refraction and reflection at the air-sea interface and solves the radiative transfer equation in the coupled system consistently. The total number of quadrature points (streams) chosen for each stratum is based on the optical properties and the accuracy required.
