This talk provides a vision for future weather prediction
research at NCAR, within the WRF community, and beyond, emphasizing high
resolution. The vision is centered on the concept of interoperability of
dynamical cores, physical parameterizations, data assimilation and component
models. It also presents the initial stages of a roadmap to achieve this and
a glimpse of where we will be in several years as well as the possible
challenges ahead.
For the purposes of this talk, unified modeling refers to unified capability
without gaps in space, time or application. It does not refer to a single set
of components designed to handle all applications. By maximizing
interoperability, we seek to reduce the barrier to entry for researchers who
wish to engage in new frontiers. Interoperability fosters gradual transitions
in support to the community and flexibility to respond to the evolution of
research needs.
The unification of WRF and MPAS will be the focus of the presentation. We
will cover (a) migration of science applications from WRF to MPAS; (b) common
physics suites; (c) coupling to other component models from the Community
Earth System Model; data assimilation for WRF and MPAS; and (e) the future of
community support for prediction research. We will also briefly explore new
capabilities, such as a regional version of MPAS and preparing WRF and MPAS
for next-generation computers.
