Contents

Increasingly models are being developed and used at higher resolutions. However, many physical processes remain unresolved and need to be parametrized. Even the highest resolution limited area models still need a parametrized representation of shallow convection, turbulence, microphysics, radiation and land surface processes. Schemes for deep convection and subgrid orography will still be needed in the foreseeable future for global NWP and climate models.

The seminar will give an overview of the relevant issues. Emphasis will be on the interaction of parametrized processes with the resolved dynamics. Increasingly, parametrization work focuses on how processes interact with each other and the dynamics and whether the feedbacks are represented realistically. This is particularly relevant at very high resolution where part of the process (e.g. convection) might be resolved. Interactions and feedbacks act at all scales from planetary and synoptic scales to meso-scales. Examples are: cloud/radiation interaction with the general circulation, boundary layer turbulence with cyclones, land surface processes with precipitation at the meso-scale and the interaction of convection with tropical variability. Lectures will also be given on the role of cloud resolving models in studying interactions and developing parametrization schemes, and on the need for stochastic components in schemes.

Participants are requested to arrive at ECMWF between 09:30 and 10:00 on Monday 1 September for registration. It is envisaged that the seminar will close at 17:00 on Thursday 4 September.

Contact and Registration

The seminar is open to the ECMWF Member States and Co-operating States. There is no registration fee for member states and no financial support is available for participants from ECMWF.

The EMS has again made available a Young Scientist Travel Award (YSTA) to support the participation of young scientists of the ECMWF Annual Seminar. This award includes financial support for travel expenditure. For further information see the attached announcement or visit http://www.emetsoc.org/awards/awards.php

Applications from non-Member States can be accepted if places are available following the deadline for Member State applications. For non-Member States a registration fee is charged. Further information: seminars@ecmwf.int
