Nonlinear processes in the climate systems

Nonlinear processes and indirect effects are currently acknowledged to be the largest source of uncertainties in the global climate. The session will be devoted to recent progress in estimates of major feedbacks in climate systems, the role of aerosols on dynamics and chemistry, on clouds including physical, chemical and biological processes. Special emphasis will be paid to atmospheric electricity in climate systems and impacts of transport emissions on atmosphere pollution in urban, rural, marine areas, with special concern to BC impacts.
General topics:

  • Feedbacks between chemistry, dynamics, and climate systems
  •  Clouds and their role in the climate system, effects of aerosols on clouds
  • Interactions between aerosols and chemistry in the climate system, including  impacts of transport emissions
  • Effects of aerosols on atmosphere pollution in urban, rural, marine areas, with special concern to BC  impacts
  • Atmospheric electricity in the climate system
