Sentences with phrase «convection scheme»

We use similar dry and moist convection schemes as in the dry and moist models above, for Titan adapted to the thermodynamic properties of methane as the condensable species.

Moist convection is represented by a simplified Betts - Miller convection scheme that relaxes temperatures toward a moist adiabat and specific humidities toward a profile with a prescribed relative humidity.

In - depth analysis reveals that the model's shallow cumulus convection scheme tends to significantly under - produce clouds during the times when shallow cumuli exist in the observations, while the deep convective and stratiform cloud schemes significantly over-produce low - level clouds throughout the day.

The links between model biases and the underlying assumptions of the shallow cumulus scheme are further diagnosed with the aid of large - eddy simulations and aircraft measurements, and by suppressing the triggering of the deep convection scheme.

The relationship between the diurnal cycle of precipitation and present and future climate was examined using the GISS - MM5 regional climate modeling system with two alternative moist convection schemes.

In the GCM, if a layer is statically unstable relative to a specified convective temperature lapse rate, a convection scheme relaxes temperatures in that layer toward an enthalpy - conserving profile with the convective lapse rate.

(The GCM can be run without a convection scheme, but the results become strongly resolution - dependent.)

The convective lapse rate can be specified to be smaller than the dry - adiabatic lapse rate, in which case the convection schemes mimics the stabilizing effect latent heat release has in moist convection.

(The convection scheme is a slight variant of that described in Frierson (2007).)

I was able to impose this condition in a convection scheme and tested several variations in a single column atmospheric model.
