The Pacific Decadal Oscillation (PDO) and North Pacific Gyre Oscillation (NPGO) are the two dominant lowfrequency modes in the North Pacific. This study focused on the simulation capability of the two leading lowfrequency modes in current-coupled models, based on 24 coupled model outputs from the Coupled Model Intercomparison Project Phase 5 (CMIP5). Results showed that most of these models cap...

The title compound, C(12)H(7)Br(2)NO(2), a biphenyl derivative, displays a twisted conformation with the two benzene rings making a dihedral angle of 55.34 (14)°. The dihedral angle between the nitro group and its parent benzene ring is 26.8 (2)°. The crystal structure is stabilized by inter-molecular C-H⋯Br and C-H⋯O inter-actions, which lead to the formation of chains propagating along the c-...
