Turbulence, transfer, transport, and transformation:
interactions among environmental systems
General Information
Date / location:
May 24-25, 2012 / Budapest, Hungary (Eötvös auditorium, room 0.83)
Topics (organized into workshops):
- Large-scale transport in the atmosphere and oceans (organizers: Imre M. Jánosi and Tamás Tél)
Atmospheric and oceanic transport processes are relevant for basic science and
applications. The series of presentations cover phenomena ranging from small
scale mixing, through spreading of pollution (trace gases, aerosols, volcanic
ash, etc.) up to the largest coherent structures characteristic of 2d
quasigeostrophic turbulence.
- Radiative transfer and atmospheres (organizer: Attila G. Császár)
Understanding radiative transfer phenomena in atmospheres is important not only to the
detailed understanding (and possibly an improved control) of the greenhouse
effect on Earth but also from a more general astrochemical and astrophysical
point of view. A scientific understanding of radiative transfer in atmospheres
requires the availability of detailed line-by-line spectroscopic information on
a small number of small molecules, an understanding of physical and chemical
properties of molecules playing crucial roles in transfer phenomena, and the
development of models (radiative transfer models, RTM) which can use all this
information for an accurate numerical modeling of quantities such as
irradiances, radiances, and radiative heating rates.
- Splitting methods: theory and applications (organizer: István Faragó)
Splitting techniques are
commonly used when large-scale models, which appear in different fields of
science and engineering, are treated numerically. Operator splitting means that
the spatial differential operator in the equations is split (decomposed) into a
sum of different sub-operators having simpler forms. In the treatment of large
scientific and engineering problems splitting procedures are an excellent tool
(and, very often, the only tool) by which huge computational tasks can be made
tractable on the available computers. This is the reason why splitting
techniques have been widely used in many fields of real-life numerical
modelling, and the number of the publications in this topic is exponentially
growing. We invite mathematicians as well as applied specialists including,
among others, physicists, chemists, meteorologists and astronomers for a forum
where we can discuss the latest achievements and possible new fields of
applications of operator splitting methods.
- Transformations in combustion systems with low environmental impact (organizer: Tamás Turányi)
Most of the electricity production and all road
transportation are based on combustion processes. The major products of
combustion are carbon dioxide and water, but the by-products may include
harmful chemicals. In the recent years, the design and development of burners,
furnaces and engines are based on numerical models. These models take into
account the turbulent flows, the transport and transformation of chemical species, and frequently calculate also
the radiative energy transfer. Using
these numerical models for the impovement of combustors and engines, the amount
of pollutants emitted to the atmosphere can be significantly decreased.
- Exchange processes in the surface layer and their environmental impacts (organizers: Imre Salma and Tamás Weidinger)
Exchange of energy, momentum
and matter including water, trace gases and aerosol particles play an important
role in the regulation of atmospheric composition, weather, and climate. Both
measurements and modelling approaches should be deployed to understand and
influence several physical, chemical and physiological properties and processes
including air quality and climate change. Research on vegetation, energy budget
closure, and flux measurements from local to landscape scale are also to be
involved. We invite micrometeorologists as well as other specialists in the
field of atmospheric chemistry and environmental
sciences to evaluate the current problems of measuring techniques, evaluation
methods, and soil-vegetation-atmosphere transfer
models. Research results and conclusions of selected micrometeorological field
campaigns (e.g., NitroEurope
Bjerringbro Field Experiment)
and fine aerosol measurements will also be discussed.
- Tracking the transition from turbulent clouds to stars - galactic cold cores in interstellar environments (organizer: L. Viktor Tóth)
The workshop discusses the
details of star formation in our Galaxy based on the ongoing observations made
by the Herschel satellite. The topics include the analysis and interpretation
of the dust continuum measurements of Herschel and the follow-up observations
with ground-based telescopes.
