Improved Cosmological Constraints from Gravitational Lens Statistics
- J. Mitchell, C. Keeton, J. A. Frieman, R. Sheth
- Physics
- 8 January 2004
We combine the Cosmic Lens All-Sky Survey (CLASS) with new Sloan Digital Sky Survey (SDSS) data on the local velocity dispersion distribution function of E/S0 galaxies, � (� ), to derive lens… Expand
The drying of Titan's dunes: Titan's methane hydrology and its impact on atmospheric circulation
- J. Mitchell
- Environmental Science
- 1 August 2008
[1] We explore the effect of a finite reservoir of methane on Titan's atmospheric circulation, precipitation patterns, and surface methane content. We develop a soil model that accounts for the… Expand
The dynamics behind Titan's methane clouds
- J. Mitchell, R. Pierrehumbert, D. Frierson, R. Caballero
- Environmental Science, Medicine
- Proceedings of the National Academy of Sciences
- 1 September 2006
We present results of an axisymmetric global circulation model of Titan with a simplified suite of atmospheric physics forced by seasonally varying insolation. The recent discovery of midlatitude… Expand
Axisymmetric, nearly inviscid circulations in non-condensing radiative-convective atmospheres
- R. Caballero, R. Pierrehumbert, J. Mitchell
- Physics
- 1 July 2008
We study the steady-state axisymmetric circulation of nearly inviscid, compressible atmospheres with no condensible component. Assuming simplified non-grey radiative transfer and instantaneous… Expand
The transition to superrotation in terrestrial atmospheres
- J. Mitchell, G. Vallis
- Physics
- 11 August 2010
[1] We show that by changing a single nondimensional number, the thermal Rossby number, global atmospheric simulations with only axisymmetric forcing pass from an Earth-like atmosphere to a… Expand
THE MECHANICAL GREENHOUSE: BURIAL OF HEAT BY TURBULENCE IN HOT JUPITER ATMOSPHERES
- A. Youdin, J. Mitchell
- Physics
- 3 August 2010
The intense irradiation received by hot Jupiters suppresses convection in the outer layers of their atmospheres and lowers their cooling rates. “Inflated” hot Jupiters, i.e., those with anomalously… Expand
Modern and glacial tropical snowlines controlled by sea surface temperature and atmospheric mixing
- A. Tripati, Sandeep Sahany, +4 authors L. Beaufort
- Geology
- 1 March 2014
During the Last Glacial Maximum, tropical glacier snowlines were lower than expected, based on estimates of tropical sea surface temperatures. Sea surface temperature reconstructions suggest the… Expand
Spontaneous Superrotation and the Role of Kelvin Waves in an Idealized Dry GCM
- S. Potter, G. K. Vallis, J. Mitchell
- Physics
- 31 January 2014
The nondimensional parameter space of an idealized dry primitive equation model is explored to find superrotating climate states. The model has no convective parameterization and is forced using a… Expand
Locally enhanced precipitation organized by planetary-scale waves on Titan
- J. Mitchell, M. Ádámkovics, R. Caballero, E. Turtle
- Environmental Science
- 1 September 2011
Saturn’s moon Titan exhibits an active weather cycle that involves methane. An analysis of cloud observations and simulations with a general circulation model reveals that convection in Titan’s… Expand
Elastic ice shells of synchronous moons: Implications for cracks on Europa and non-synchronous rotation of Titan
- P. Goldreich, J. Mitchell
- Physics
- 30 September 2009
A number of synchronous moons are thought to harbor water oceans beneath their outer ice shells. A subsurface ocean frictionally decouples the shell from the interior. This has led to proposals that… Expand
