Sentences with phrase «areal fraction»

The scheme depends on two parameters: the areal fraction of the vertically - mixed region within the horizontal grid cell, and the density difference between the mean and the unstratified profiles at the surface.

b) Distribution of the records by latitude (grey histogram) and areal fraction of the planet in 5 ° steps (blue line).

What is consistent about the 2.3 W / m ^ 2 number is that this also happens to be the radiative balance for the average global anomaly of 0.8 C, which includes pro-rated SST and land forcing according to the areal fractions.

Not exact matches

(Note that radiative forcing is not necessarily proportional to reduction in atmospheric transparency, because relatively opaque layers in the lower warmer troposphere (water vapor, and for the fractional area they occupy, low level clouds) can reduce atmospheric transparency a lot on their own while only reducing the net upward LW flux above them by a small amount; colder, higher - level clouds will have a bigger effect on the net upward LW flux above them (per fraction of areal coverage), though they will have a smaller effect on the net upward LW flux below them.

The former is defined as the areal sum of sea ice covering the ocean (sea ice + open ocean), whereas the latter «area» definition counts only sea ice covering a fraction of the ocean (sea ice only).
