Fifth Symposium on Aerosol–Cloud–Climate Interactions

Conferences and Symposia Conference Program

View by day or program, includes author index and personal scheduler

      The theme for the 2013 AMS Annual Meeting is “Taking Predictions to the Next Level: Expanding Beyond Today's Weather, Water, and Climate Forecasting and Projections”.  Over the past 60 years the meteorological community has made tremendous strides in making prediction a fundamental part of its scientific and operational/service heritage through the development and application of complex numerical models involving the atmosphere, ocean, land and cryosphere components of the Earth System. This theme will serve as a catalyst for the 2013 AMS annual meeting by focusing the attention of the research and operational communities, including those who are involved in accelerating the transition of research results into operations.  Furthermore, the increasing use of predictions by decision makers throughout federal, state, and local emergency management government agencies and by private/commercial sectors will serve as an important component for this annual meeting along with the extension of predictive capabilities into a broader domain, including public health, food security, air and water quality, alternative energy and responses to climate trends.

      The 2007 Intergovernmental Panel on Climate Change (IPCC) assessment report highlights the scientific and societal importance for improved understanding on the aerosol–cloud-climate interactions to better assess the linkages between anthropogenic activities and climate.  In line with the theme of forecasts and projections, the symposium of Aerosol–Cloud–Climate Interactions will organize sessions and have discussions about the extent to what knowledge of aerosols can be added to the prediction skill, from the weather to the climate scales. The symposium will bring together experts in atmospheric chemistry, aerosols, radiation, clouds, and climate to exchange ideas on the subject of aerosol-cloud-climate interactions. The symposium will include invited and contributed oral and poster sessions.  It will provide a forum to review current research status on this subject, identify research needs, define research priorities and new research approaches, and facilitate dialogue among atmospheric chemists, physicists, and meteorologists to tackle research challenges in aerosol–cloud-climate interactions.

      To have a more integrated program and reduce conflicting sessions in the field regarding aerosol-cloud interactions, we will coordinate with other programs especially Atmospheric Chemistry, Weather Modification and Satellite Meteorology to have joint sessions.

Papers are solicited in all aspects relevant to this topic including:

• Cloud condensation nuclei (CCN) and ice nuclei (IN)
• Aerosol direct and indirect radiative forcings
• Impacts of anthropogenic aerosols on clouds, precipitation, circulation, and severe storms (joint with Weather Modification)
• The impacts of secondary organic aerosols (SOA) on climate
• Impacts of natural aerosols (e.g., biogenic, dust, sea salt and smoke) on climate- laboratory, field, satellite, and modeling studies (joint with Atmospheric Chemistry and Satellite Meteorology)
• Aerosol-cloud interaction representations in regional and global models and associated climate impact.
• Chemistry-aerosol-cloud/climate interactions (joint with Atmospheric Chemistry).
• Aerosol-cloud interactions in weather forecast (joint with Weather Modification).

      The 2013 meeting will also feature a joint session sponsored by Atmospheric Chemistry, Climate Variability and Change, the Policy Symposium, and the Aerosol-Cloud-Climate Interactions Symposium.  Papers are solicited highlighting policy-relevant research and efforts to connect science and policy in this arena, in keeping with this meeting's thematic emphasis on ‘accelerating the transition of research results into operations.’

      Graduate and undergraduate students are highly encouraged to submit an abstract describing your research.  Best student oral presentations and poster papers will be selected at the meeting and awarded by the Atmospheric Chemistry Committee soon after the meeting.
