Simple and complex climate models suggest a hard snowball – a completely ice-covered planet – is one of the steady-states of Earth’s climate. However, a seemingly insurmountable challenge to the hard-snowball hypothesis lies in the difficulty i

Jupiter's moon Europa likely hosts a saltwater ocean beneath its icy surface. Geothermal heating and rotating convection in the ocean may drive a global overturning circulation that redistributes heat vertically and meridionally, preferentially warmi

We review recent observations and models concerning the dynamics of Cryogenian global glaciation and their biological consequences.
Geological evidence indicates that grounded ice sheets reached sea level at all latitudes during two long-lived C

Enceladus' south polar sea

Autor: Jason C. Goodman, Geoffrey C. Collins

Publikováno v: Icarus. 189:72-82

Recent observations of the south pole of Saturn's moon Enceladus by the Cassini spacecraft have revealed an active world, powered by internal heat. In this paper, we propose that localized subsurface melting on Enceladus has produced an internal sout

Using Neutral Singular Vectors to Study Low-Frequency Atmospheric Variability

Autor: John Marshall, Jason C. Goodman

Publikováno v: Journal of the Atmospheric Sciences. 59:3206-3222

The authors explore the use of the “neutral vectors” of a linearized version of a global quasigeostrophic atmospheric model with realistic mean flow in the study of the nonlinear model's low-frequency variability. Neutral vectors are the (right)
