Submit an Abstract to this Session Please know the abstract submission deadline has passed. There are no exceptions to this deadline and no new abstracts can be submitted.
You can still search the program to see your colleague�s abstract submissions as well as the sessions submitted for the 2016 Fall Meeting. The final program will be released in early October.


Session ID#: 12513

Session Description:
Mixed-phase clouds contain both liquid and ice water in the same atmospheric domain that interact via microphysical processes.  They have a variety of distinct phenomena, impacting the atmospheric radiation balance and the hydrological cycle, which are sensitive to the partitioning of cloud phase.

We invite presentations that advance our knowledge on mixed-phase clouds, with the focus on the following topics: a) ground-based, aircraft and satellite observations of mixed-phase clouds using a range of instruments (radar, lidar, microwave radiometer, radiosonde, Doppler radar spectra), characterization of cloud microphysics, retrieval algorithms, validations, datasets;  b) modeling of mixed-phase clouds in numerical models of all scales; c) precipitation dependence on abundance of natural and anthropogenic aerosol particles, air pollution and mixed-phase microphysical schemes, case and sensitivity studies; d) interactions between atmospheric constituents and mixed–phase clouds, such as ice nucleation, aerosol scavenging, and cloud chemistry; e) cloud-radiation feedbacks in the climate system involving mixed-phase clouds.
