The challenge of accurately quantifying future megadrought risk in the American Southwest

open access: yesGeophysical Research Letters, 2016
American Southwest (ASW) megadroughts represent decadal‐scale periods of dry conditions the near‐term risks of which arise from natural low‐frequency hydroclimate variability and anthropogenic forcing. A large single‐climate‐model ensemble indicates that

Composition for cardinal directions by decomposing horizontal and vertical constraints [PDF]

open access: yes, 2003
In this paper, we demonstrate how to group the nine cardinal directions into sets and use them to compute a composition table. Firstly, we define each cardinal direction in terms of a certain set of constraints.
