Dear Colleagues!

We would like to invite you to submit contributions to our session
"Stochastic Approaches for Multiscale Modelling in Geosciences"
at this years EGU General Assembly in Vienna, Austria, 27 April - 02 May 

The deadline for abstract submission is January 16th at 13:00 CET.

Information about our session NP8.1 and how to submit an abstract can be 
found at:

The myriad physical processes that occur over a wide range of spatial 
and temporal scales in geophysical systems give rise to complex behavior 
and low frequency variability. Neither the importance of understanding 
the low frequency variability nor the difficulty of being able to 
appropriately model it can be over-emphasized. Indeed, several 
deficiencies in predicting such systems (e.g., climate) can be traced 
back to a misrepresentation of scale interactions. The latter, in turn, 
leads to systematic biases in resolved-scale processes.

 From the modeling point of view, given the non-uniqueness of small 
scales with respect to large scales and possible separation of scales 
between those explicitly modeled and those studied, stochastic 
approaches can provide more realistic representations of the multi-scale 
variability and allow transitions between attractors. On the other hand, 
such approaches also allow for a quantification of uncertainties that 
are inherent in the modeling of these multi-scale systems. It is 
important to note that such quantification of uncertainty is directly 
linked to the ability to compare models and observations, and combine 
them as in data assimilation techniques.

We invite contributions spanning fundamental studies of stochastic 
approaches, stochastic modelling of geophysical systems, stochastic 
parameterisations, data assimilation using stochastic methods and 
extreme value studies using a stochastic framework

Looking forward to seeing you at EGU,
