A radiation model is constructed that includes radiative interactions with atmospheric gases, as well as parameterized treatments of scattering and absorption/emission by cloud droplets and haze particles. A unified treatment of solar and terrestrial radiation is obtained by using identical cloud and haze parameterization procedure for the shortwave and longwave region. The influence of the rel...

Abstract Modeling evidence suggests that the Inter-decadal Pacific Oscillation (IPO) can remotely affect tropical Atlantic sea surface temperature (SST) variability. However, root causes of IPO-tropical inter-basin teleconnections are not fully understood. Using idealized pacemaker experiments wherein observed IPO-SST anomalies specified, we show a warm-phase anomaly drives basin-wide SST warmi...

During the Northern hemisphere winter season, biomass burning is widespread in West Africa, yet the total tropospheric column ozone values (<30 DU) over much of the Tropical Atlantic Ocean (15 N–5 S) are relatively low. At the same time, the tropospheric column ozone values in the Southern Tropical Atlantic are higher than those in the Northern Hemisphere (ozone paradox). We examine the causes ...
