Abstract: Recent work has shown that observations of tropical precipitation conform to properties associated with critical phenomena in other systems. Here some of these universal properties are used to probe the physics of tropical ...

Abstract: Tropical land climate sensitivities to surface properties are studied using an intermediate complexity atmosphere model. The focus here is on land surface vegetation feedbacks to the atmosphere through surface conductance ...

Abstract: Although the global vegetation distribution is largely controlled by the large-scale climate pattern, the observed vegetation?rainfall relationship is also influenced by vegetation feedback and climate variability. Using ...

Abstract: Paleoevidence indicates that generally wetter conditions existed in the Sahara during the mid-Holocene. Climate modeling studies addressing this issue generally agree that mid-Holocene values of the earth?s orbital parameters ...

Abstract: ropical deep convective transition characteristics, including precipitation pickup, occurrence probability, and distribution tails related to extreme events, are analyzed using uncoupled and coupled versions of the Community ...

Abstract: roperties of the transition to strong deep convection, as previously observed in satellite precipitation statistics, are analyzed using parcel stability computations and a convective plume velocity equation. A set of ...
