We study the properties of axial vector mesons a1 and b1 as relativistic S-wave states which are predicted in the Ũ(12)-scheme, through the analyses of their radiative and pionic decays. Specifically, partial widths of the strong a1(b1) → ρ(ω)π processes, their D/S-wave amplitude ratios, and radiative transition widths of a1(b1) → πγ processes are calculated by using a simple decay interaction ...

The equation of radiative energy balance in homogeneous We let L denote the mean horizontal photon path length in plane-parallel cloud accounts for the photon transport in clouds. Major contributors to E(x,y) are those sections of vertical direction alone. From this equation, we can evaluate pixel located near its sides and having lengths on the order of absorption as a difference of the net ra...

A number of unsolved problems in atmospheric radiative transfer are presented, including the light scattering and absorption by aerosols, the effect of mountains on radiation fields, and radiative transfer in the atmosphere–ocean system, with a specific application to the Asia–Pacific region. We discuss the issues of two nonspherical and inhomogeneous aerosol types, dust and black carbon, regar...
