The Role of Radiative Heating in the MJO

7 August 2017

Johnson, Richard H; Xie, Shaocheng

Supported by: ARM ASR

Research area: Cloud Processes

Despite its broad impacts on global weather and climate, the Madden-Julian Oscillation (MJO), which dominates tropical intra-seasonal variability, remains poorly represented in many weather forecasts and global climate model simulations. To improve our understanding of key processes of MJO initiation and propagation, this study, resulting from an ASR grant, uses [...]

Ice formation in stratiform mixed-phase clouds at warm temperatures

19 July 2017

Zhang, Damao

Supported by: ARM ASR

Research area: Cloud Processes

Low-level stratiform clouds have a high occurrence in polar regions. Accurate cloud thermodynamic phase determination is required to perform cloud property retrievals and to study aerosol-cloud interactions with remote-sensing measurements. However, ice particle formation in slightly supercooled stratiform clouds is still not well documented or understood.

Impact of Dispersion on CAM5 Cloud Radiative and Aerosol Indirect Effects

18 July 2017

Liu, Yangang

Supported by: ASR

Research area: Cloud-Aerosol-Precipitation Interactions

Accurate representation of cloud microphysics and aerosol-cloud interactions is essential to improving the ability of large-scale models to simulate clouds, precipitation, and aerosol indirect effects, and much remains to be done. Particularly understudied is the spectral dispersion of cloud droplet size distribution--how water is distributed among cloud droplets of different [...]
