AW5Space forcing of the Earth's and planets' climate
|Convener: M. Messerotti | Co-Conveners: H. Lundstedt , K. Matthes|
Weather and climate are respectively the short- and long-term response of planetary atmospheres to energy input from space and planetary sources that is processed in complex inner cycles dependent on and modified by the varying coupling with both the intrinsic planetary characteristics and the presence of living species interacting with the planetary environment.
Due to the complexity of the weather and climate systems, their predictability on the short term and the construction of possible scenarios on the long term are heavily dependent on the level of knowledge of the potential forcing agents and the possible action of amplifying processes.
In the case of the Earth, space forcing from the e.g. the Sun has still to be definitely ascertained in a quantitative way as well as other more debated agents such as galactic cosmic rays, not considered yet as a potential forcing due to a poor understanding of their potential role despite that interesting indications come from the analysis of the Earth palaeoclimate.
Similar considerations hold for the non-terrestrial planetary environments, whose wheather and climate are known to a lesser level of detail.
Hence, space weather and space climate agents certainly deserve a deep analysis in order to define their role as potential concurrent drivers of the Earth and planets climate and weather.
The aim of this session is to provide the state-of-the-art scenario on the knowledge in this framework and to point out the future perspectives for pointing out possible interrelationships between Earth and planets and Space Meteorology by assessing the level of coupling in the acting physical systems and processes.
Authors are invited to submit abstracts with focus on one ore more of the following topics relevant to space sources of potential Earth and planets weather and climate forcing agents, and to the analysis of their time evolution and signatures on terrestrial and planetary records of climate and palaeoclimate: - Solar electromagnetic emission; - Solar Wind; - Solar Cosmic Rays; - Galactic Cosmic Rays; - Ultra-High Energy Gamma Ray Bursts.
The session will be featuring oral and poster presentations.
