Sentences with phrase «higher cloud fractions»

Part of this sensitivity is attributed to a physically realistic positive radiative feedback, whereby a propensity toward higher cloud fractions in any given simulation is amplified by longwave radiative cooling.

The results were striking: across the intercomparison the cloud fraction was found to vary by a factor of almost five and the amount of liquid water in the clouds by nearly a factor of twelve, with the simulations having the highest cloud fraction and liquid water agreeing most closely with the observations.

(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 calculated solar fraction for the full month was 0.989 — very nice — probably a bit higher than a typical March, which might have more clouds.

While ARs are responsible for a large fraction of heavy precipitation in that region during winter, much of the rest of the orographic precipitation occurs in post-frontal clouds, which are typically quite shallow, with tops just high enough to pass the mountain barrier.

But, the amount of energy deposited is also low, as clouds have a high albedo, reflecting some fraction of the energy back to space and absorbing another fraction, which heats the air above the surface.
