Interaction of deep and shallow convection is key to Madden-Julian Oscillation simulation
[1] This study investigates the role of the interaction between deep and shallow convection in MJO simulation using the NCAR CAM3. Two simulations were performed, one using a revised Zhang-McFarlaneExpand

Impact of a modified convective scheme on the Madden‐Julian Oscillation and El Niño–Southern Oscillation in a coupled climate model
[1] The connection between the intraseasonal Madden-Julian Oscillation (MJO) and interannual El Nino–Southern Oscillation (ENSO) has been proposed and investigated for the last two decades. However,Expand

A penalty PALM method for sparse portfolio selection problems
In this paper, we propose a penalty proximal alternating linearized minimization method for the large-scale sparse portfolio problems in which a sequence of penalty subproblems are solved by utilizing sparse projection techniques. Expand

Saliency Detection via Nonlocal L_0 Minimization
In this paper, by observing the intrinsic sparsity of saliency map for the image, we propose a novel nonlocal \(L_{0}\) minimization framework to extract the sparse geometric structure of the saliency maps for natural images. Expand

Role of Climate Feedback in El Niño–Like SST Response to Global Warming
AbstractUnder global warming from the doubling of CO2, the equatorial Pacific experiences an El Nino–like warming, as simulated by most global climate models. A new climate feedback and responseExpand
