Abstract

The aerosol-cloud interactions importantly influence the energy and water cycle of Earth-atmosphere system. The uncertainty of climate models is partly due to the lack of large-scale observational constraints of interaction between aerosol and water cloud. Based on CATS lidar time-resolved observations over the global marine region during 2015–2017, this study investigates the vertical effect of aerosol on marine water clouds, and evaluates the covariate influence of meteorological factors combined with European Centre for Medium-Range Weather Forecasts (ECMWF) reanalysis meteorological data. The mutual roles between aerosols as cloud condensation nucleation (CCN) and meteorological variables (temperature and relative humidity) contribute to the non-linear relationship of interactions between aerosol and water clouds. The results provide effective constraints for the parameterizations of aerosol-cloud interactions in current climate models.

期刊介绍： The Journal of Atmospheric and Solar-Terrestrial Physics (JASTP) is an international journal concerned with the inter-disciplinary science of the Earth''s atmospheric and space environment, especially the highly varied and highly variable physical phenomena that occur in this natural laboratory and the processes that couple them. The journal covers the physical processes operating in the troposphere, stratosphere, mesosphere, thermosphere, ionosphere, magnetosphere, the Sun, interplanetary medium, and heliosphere. Phenomena occurring in other "spheres", solar influences on climate, and supporting laboratory measurements are also considered. The journal deals especially with the coupling between the different regions. Solar flares, coronal mass ejections, and other energetic events on the Sun create interesting and important perturbations in the near-Earth space environment. The physics of such "space weather" is central to the Journal of Atmospheric and Solar-Terrestrial Physics and the journal welcomes papers that lead in the direction of a predictive understanding of the coupled system. Regarding the upper atmosphere, the subjects of aeronomy, geomagnetism and geoelectricity, auroral phenomena, radio wave propagation, and plasma instabilities, are examples within the broad field of solar-terrestrial physics which emphasise the energy exchange between the solar wind, the magnetospheric and ionospheric plasmas, and the neutral gas. In the lower atmosphere, topics covered range from mesoscale to global scale dynamics, to atmospheric electricity, lightning and its effects, and to anthropogenic changes.
