A Low Temperature Transfer of ALH84001 from Mars to Earth
(American Association for the Advancement of Science (AAAS), 2000)
The ejection of material from Mars is thought to be caused by large impacts that would heat much of the ejecta to high temperatures. Images of the magnetic field of martian meteorite ALH84001 reveal a spatially heterogeneous ...
Sea Ice as the Glacial Cycles’ Climate Switch: Role of Seasonal and Orbital Forcing
(American Geophysical Union, 2000)
A box model of the coupled ocean, atmosphere, sea ice, and land ice climate system is used to study glacial-interglacial oscillations under seasonally and orbitally varying solar forcing. The dominant 100 kyr oscillation ...
Proximity of the Present-Day Thermohaline Circulation to an Instability Threshold
(American Meteorological Society, 2000)
The relation between the mean state of the thermohaline circulation (THC) and its stability is examined using a realistic-geometry primitive equation coupled ocean–atmosphere–ice global general circulation model. The main ...
Elastodynamic Analysis for Slow Tectonic Loading with Spontaneous Rupture Episodes on Faults with Rate- and State-dependent Friction
(American Geophysical Union, 2000)
We present an efficient and rigorous numerical procedure for calculating the elastodynamic response of a fault subjected to slow tectonic loading processes of long duration within which there are episodes of rapid earthquake ...
Uncertainties in Thermohaline Circulation Response to Greenhouse Warming
(American Geophysical Union, 2000)
The uncertainty in the response of the thermohaline circulation to greenhouse forcing due to the use of flux adjustments in coupled ocean‐atmosphere models is evaluated. This is done by using a different yet physically ...
ENSO’s Phase Locking to the Seasonal Cycle in the Fast-SST, Fast-Wave, and Mixed-Mode Regimes
(American Meteorological Society, 2000)
The physical mechanism underlying ENSO’s phase locking to the seasonal cycle is examined in three parameter regimes: the fast-SST limit, the fast-wave limit, and the mixed SST–wave dynamics regime. The seasonal cycle is ...
