<bigger>GEWEX Atmospheric Boundary Layer Study (GABLS)
GEWEX is initiating a new project focusing on the representation of the
Atmospheric Boundary Layer in regional and global models. The project
referred to as 'GEWEX Atmospheric Boundary Layers Studies (GABLS)', was
approved by the SSG.
The main goal of GABLS is to improve the representation of the
Atmospheric Boundary Layer (ABL) in models on the basis of an advanced
understanding of the relevant processes. As such GABLS will provide a
framework, similar to those established for GCSS and GLASS, in which
scientists working on boundary layer research issues at different
scales will interact.
The ABL is an important aspect of the physics in regional and global
models. It is particularly important when discussing coupled
atmosphere/land-surface/ocean models. The intention is to organize an
international activity under the GEWEX Modelling and Prediction Panel
(GMPP) aimed at stimulating and coordinating research on boundary layer
physics. GABLS like GLASS and GCSS will undertake its work in
association with the other components of WCRP and especially with WGNE,
which endorsed GABLS at its October 2000 meeting. This interaction
will ensure that GABLS establishes the same proactive posture in
engaging the NWP/GCM community that has been used in GCSS and GLASS.
GABLS will include representatives of the weather and climate modelling
communities in their deliberations and have them present issues of
relevance to large-scale models, which GABLS will then integrate into
its work plans.
Dr Bert Holtslag, of the Meteorology and Air Quality Section, at the
Wageningen University in The Netherlands, has agreed to Chair GABLS.
Dr Holtslagユs plans for an initial workshop for GABLS were accepted.
The meeting will be held in conjunction with the "Climate conference
2001" being planned for August 20-24, 2001, in Utrecht, The Netherlands
(convened by Dr Han van Dop, Utrecht University). A session at the
Conference on the representation of "Boundary layers in climate models"
is already being planned, in addition to related workshops (convened by
Peter Duynkerke, Utrecht University and Bert Holtslag, Wageningen
University). Invited contributions at the conference will be given by
Dr Anton Beljaars (ECMWF), Dr Dave Randall (CSU) and Dr Bjorn Stevens
(UCLA). These relevant sessions are expected to result in a list of
specific scientific issues and to go a long way toward development of a
GABLS Science and Implementation Plan. A proposed structure for a
series of GABLS Working Groups and points of contact to begin work in
the GABLS framework will be presented and discussed at the Conference.
Finalization of these plans is an expected outcome of the meeting.
