<p class="MsoNormal" style="margin: 0in 0in 0.0001pt;"><span style="font-size: 16px;">The Fall AGU meeting will host a number of sessions related to downscaling of weather and climate models. We have organized one session that will focus on the methodology
used in dynamical downscaling, and the questions regarding the most effective way to drive regional models in this context. It will also examine the tradeoff between dynamical downscaling and high resolution globally downscaled GCM approaches. If you are
working in these areas, we invite you to submit an abstract for this session.</span><font size="3"><o:p></o:p></font></p>

<p class="MsoNormal" style="font-size: 11pt; margin: 0in 0in 0.0001pt;"><span style="font-size: 12pt; font-family: 'Times New Roman', serif;">Dynamical downscaling - the use of regional models to produce high-resolution weather and climate impacts from coarse
resolution global climate model (GCM) simulations - has become commonplace on today’s high-end computing systems. Still, there remains great uncertainty surrounding the design of downscaling approaches and the value added of the high-resolution solutions.
Fundamental questions exist as to whether regional climate models should simply be forced by the coarse resolution GCMs along outer domain boundaries or whether a numerical nudging within the domain is required. Additionally, global downscaling has evolved
as an alternative, using high-resolution cloud-permitting global models to simulate slices in time starting from a coarse resolution GCM simulation. Similar to regional downscaling experiments, the question of if and how to relax to the coarse resolution
simulation remains. This session invites studies of the issues surrounding the design, validation and appropriate use of dynamical downscaling methodologies for regional or global simulations.<o:p></o:p></span></p>
