Support Scientist HAFS Developer
I.M. Systems Group, Inc. (IMSG) is seeking a candidate to support the Environmental Modeling Center (EMC) of the National Centers for Environmental Prediction (NCEP) in carrying out research and development work related to future operational hurricane forecast systems. The candidate’s work will involve the development, execution, testing, and evaluation of several different components of the proposed FV3-based HAFS (Hurricane Analysis and Forecast System) that include hurricane dynamics, multi-level high-resolution movable nests, physics, data assimilation, vortex initialization, coupling to ocean, wave, land, storm surge and inundation models. The work location is at the NOAA Center for Weather and Climate Prediction (NCWCP) in College Park, MD.
The candidate will perform the job duties in a high-quality, independent, and collaborative way, assisting in managing projects and developing and applying innovative methods for the primary work areas described below. The candidate will work with EMC scientists and external collaborators to set up comprehensive tests of new hurricane models, and evaluate the results using objective verification metrics and model diagnostics. The candidate will work on several tasks, including developing advanced nesting and coupling techniques for Hurricane modeling using next-generation Finite Volume Cubed-Sphere (FV3) model, and/or advanced hurricane physical parameterization techniques applicable at high resolutions, and/or advanced inner-core data assimilation methods for conventional and satellite data, determining areas of physics improvement needed to increase forecast skill and transitioning hurricane physics from existing operational models into the FV3-based hurricane models within the Unified Forecast System Common Community Physics Package (CCPP) framework. The candidate will work with advanced NOAA Environmental Modeling System (NEMS) infrastructure and multi-scale modeling framework, improving hurricane specific physics, data assimilation, dynamics, and high-resolution telescoping and moving nest techniques. This work will include:
● Develop new or improving existing nesting and coupling schemes for multi-scale high-resolution hurricane models.
● Implement and test advanced hurricane-specific physical parameterizations into the FV3-based CCPP framework.
● Develop new or improved inner-core data assimilation algorithms for FV3.
● Design, setup, and execute pre-implementation tests for annual experimental and operational hurricane model upgrades.
● Develop advanced initialization methods for experimental and operational hurricane models.
● Develop and implement generalized nesting techniques for global-to-local scale applications.
● Develop advanced scripts for flexible end-to-end system integration and automation, and allow for additional functionalities.
