Sentences with phrase «ocean diffusivity»

Ocean parameters: horizontal and vertical ocean diffusivity k H = 200 — 5,000 -LCB- 2000 -RCB- m2 / s, k V = 0.1 — 1.0 × 10 − 4 -LCB- 0.3 × 10 − 4 -RCB- m2 / s at top, 1.1 — 2.0 × 10 − 4 -LCB- 1.3 × 10 − 4 -RCB- m2 / s at ocean bottom (vertical profile after Bryan Lewis).

d Uncertainties taken into account (e.g., uncertainty in ocean diffusivity K, or total aerosol forcing εforc).

Using an effective ocean diffusivity of 0.65 cm ^ 2 / s (which is the central estimate derived in the Forest 06 study), the surface temperature response to a step forcing increase reaches about 90 % of its ultimate level within 25 years, if I've got everythng right.

The treatment of uncertainty in the ocean's uptake of heat varies, from assuming a fixed value for a model's ocean diffusivity (Andronova and Schlesinger, 2001) to trying to allow for a wide range of ocean mixing parameters (Knutti et al., 2002, 2003) or systematically varying the ocean's effective diffusivity (e.g., Forest et al., 2002, 2006; Frame et al., 2005).

A detailed reanalysis is presented of a «Bayesian» climate parameter study (Forest et al., 2006) that estimates climate sensitivity (ECS) jointly with effective ocean diffusivity and aerosol forcing, using optimal fingerprints to compare multi-decadal observations with simulations by the MIT 2D climate model at varying settings of the three climate parameters.

Effective ocean diffusivity, Kv, and total aerosol forcing, Faer, are estimated simultaneously with S.

The other two are climate sensitivity and deep - ocean diffusivity.

His paper contains more discussion on the deep - ocean diffusivity, joint distributions of aerosol forcing and other parameters are not discussed.
