Modelling H 3 + in planetary atmospheres: effects of vertical gradients on observed quantities

A simple expression for vertical convective fluxes in planetary atmospheres

We explore the vertical convective flux Fc in a radiative-convective grey atmosphere. An expression of the form Fc = Fsτo/(C +Dτo) appears useful, where Fs is the shortwave flux absorbed at the base of an atmosphere with longwave optical depth τo and C and D are constants. We find excellent agreement with an idealized grey radiative-convective model with no shortwave absorption for D = 1 and C ...

H3+ cooling in planetary atmospheres.

We review the role of H3+ in planetary atmospheres, with a particular emphasis on its effect in cooling and stabilising, an effect that has been termed the "H3+ thermostat" (see Miller et al., Philos. Trans. R. Soc. London, Ser. A, 2000, 58, 2485). In the course of our analysis of this effect, we found that cooling functions that make use of the partition function, Q(T) based on the calculated ...

the effects of changing roughness on the flow structure in the bends

flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
