VLab Forum Members,
Just a quick reminder that the May VLab Forum, which was
rescheduled for Friday, June 17, 2022, at 2:35 – 3:30pm (Eastern
Time), will take place this week. This is the first of two VLab
Forum talks this month and features a presentation by Panagiotis
Velissariou, Saeed Moghimi, Edward Myers, and Andre Van der
Westhuysen titled "Development of a NUOPC enabled Parametric
Hurricane model (PaHM) as an atmospheric component for CoastalApp to
support on-demand wave-surge coupled applications". We hope you
can attend.
To participate in the forum, please register
for the webinar
(NOTE: If you registered for the webinar when it
was scheduled for May, there is no need to reregister for the
webinar at its new date and time.
Abstract:
Parametric atmospheric models are very useful on forcing ocean and
wave models as they are light-weight and they do not require much
time or computational resources to produce the on-demand wind fields
for coastal and regional ocean simulations (e.g., storm surge
modeling studies). The Parametric Hurricane Modeling system (PaHM)
follows the same philosophy as well. PaHM
(https://github.com/noaa-ocs-modeling/PaHM) is developed by the
Coastal Marine Modeling Branch (CMMB) of the Coast Survey
Development Laboratory (CSDL) under the umbrella of the Office of
Coast Survey (OCS), NOAA/NOS. PaHM is a modeling system that
contains a multiplicity of parametric models (Holland Models [1980,
2010], and the Generalized Asymmetric Vortex Model – GAHM), and it
is left to the user to activate any of these models to generate the
wind fields at run time. In the case of the presence of multiple
storms in the basin, PaHM has the capability to integrate all the
storms when generating the wind fields. PaHM can be used either as a
standalone atmospheric model or can be coupled with ocean and wave
models via NOAA’s Environmental Modeling System (NEMS), a common
modeling coupling framework that implements the National Unified
Operational Prediction Capability (NUOPC).
For this case study for Hurricane Florence (2018), we use
CoastalApp (PaHM is a modeling component of the application),
https://github.com/noaa-ocs-modeling/CoastalApp. CoastalApp is a
flexible and portable modeling framework for coastal applications
and regional forecasts. CoastalApp consists of multiple coupled
modeling components that link the atmospheric, ocean and terrestrial
realms under one common framework coupled using ESMF/NUOPC coupling capabilities.
We would like to acknowledge support from 3A-3a-4 Hurricane
Supplemental 2018 and express our gratitude to Nicole Kurkowski -
NOAA Federal for her exceptional leadership.
