Query: An Analytic Radiative-Convective Model for Planetary Atmospheres   We present an analytic 1-D radiative-convective model of the thermal
structure of planetary atmospheres. Our model assumes that thermal radiative
transfer is gray and can be represented by the two-stream approximation. Model
atmospheres are assumed to be in hydrostatic equilibrium, with a power law
scaling between the atmospheric pressure and the gray thermal optical depth.
The convective portions of our models are taken to follow adiabats that account
for condensation of volatiles through a scaling parameter to the dry adiabat.
By combining these assumptions, we produce simple, analytic expressions that
allow calculations of the atmospheric pressure-temperature profile, as well as
expressions for the profiles of thermal radiative flux and convective flux. We
explore the general behaviors of our model. These investigations encompass (1)
worlds where atmospheric attenuation of sunlight is weak, which we show tend to
have relatively high radiative-convective boundaries, (2) worlds with some
attenuation of sunlight throughout the atmosphere, which we show can produce
either shallow or deep radiative-convective boundaries, depending on the
strength of sunlight attenuation, and (3) strongly irradiated giant planets
(including Hot Jupiters), where we explore the conditions under which these
worlds acquire detached convective regions in their mid-tropospheres. Finally,
we validate our model and demonstrate its utility through comparisons to the
average observed thermal structure of Venus, Jupiter, and Titan, and by
comparing computed flux profiles to more complex models.
