The workshop "Parameterization of Lakes in Numerical Weather Prediction
and Climate Modelling" will be held on 18-20 September 2008, in St.
Petersburg (Zelenogorsk), Russia. The workshop is supported by the
Nordic Network on Fine-Scale Atmospheric Modelling (NetFAM),
International Association for the Promotion of Co-operation with
Scientists from the New Independent States of the Former Soviet Union
(INTAS), EU Programme TEMPUS, and Russian Foundation for Basic Research
(RFFI).
Lakes significantly affect the structure of the atmospheric boundary
layer and therefore the surface fluxes of heat, water vapor, and
momentum. In numerical weather prediction (NWP) and climate models, the
effect of lakes should be adequately parameterized. The problem becomes
particularly pressing as the horizontal resolution of numerical models
is refined. A large number of small-to-medium size lakes, which are
indistinguishable sub-grid-scale features in low-resolution models,
become resolved grid-scale features in high-resolution models. A
physically sound and computationally efficient lake model
(parameterization scheme) is then required to predict the lake surface
temperature and its time-rate-of-change. An interest in the problem of
lakes has led to the development of several lake parameterization
schemes for use in NWP and climate models, ranging from the simplest
one-layer schemes to very sophisticated three-dimensional schemes. These
schemes have been applied in NWP, climate studies, and related
environmental problems with a varying degree of success, considerable
experience has been accumulated, and numerous problems have been
encountered.
The aim of the workshop is to join NWP and climate modelers dealing with
the parameterization of lakes in order to share their experience, review
the state of art, and discuss challenging problems, strategy of further
development, tasks, and plans. Emphasis is given to lake
parameterization schemes for NWP and climate models, external-parameter
data sets, data assimilation, and off-line applications of lake models
(parameterization schemes).
