Abstract
|
The triggering of a robust water cycle on Mars might have been caused by the gigantic flooding events evidenced by outflow channels. We use the Ames Mars General Circulation Model (MGCM) to test this hypothesis, studying how these presumably abrupt eruptions of water might have affected the climate of Mars in the past. We model where the water ultimately went as part of a transient atmospheric water cycle, to answer questions including: (1) Can sudden introductions of large amounts of water on the Martian surface lead to a new equilibrated water cycle. (2) What are the roles of water vapor and water ice clouds to sudden changes in the water cycle on Mars. (3) How are radiative feedbacks involved with this. (4) What is the ultimate fate of the outflow water. (5) Can we tie certain geological features to outflow water redistributed by the atmosphere.
