  • Overview


    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 the operational hurricane forecast systems. The candidate’s work will involve the development, execution, testing and evaluation of several different components of the operational HWRF (Hurricane Weather and Research Forecast) and HMON (Hurricanes in a Multi-scale Ocean-coupled Non-hydrostatic) modeling systems that include physics, data assimilation, dynamics, vortex initialization, coupling to ocean, wave, land, storm surge and inundation models. 



    The successful 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 the hurricane models, and evaluate the results using objective verification metrics and model diagnostics. The candidate will work on several tasks, including implementing advanced hurricane physical parameterization techniques applicable at 1-3 km resolutions, determining areas of physics improvement needed to increase forecast skill, and transitioning the HWRF and HMON physics into the next-generation Finite Volume Cubed-Sphere (FV3) hurricane models within the Unified Forecast System framework. The candidate will work on 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 physical parameterization schemes for multi-scale high-resolution hurricane models.
    • Implement and test advanced hurricane-specific physical parameterizations into the FV3-based Common Community Physics Package (CCPP) framework.
    • Design, setup, and execute pre-implementation tests for annual operational hurricane model upgrades.
    • Develop advanced data assimilation and initialization methods for 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.

    Candidates must be a U.S Citizen or Green Card Holder to qualify (please indicate in your cover letter)


    Ph.D. in atmospheric sciences or meteorology, oceanic, mathematics, or a related physical science with at least 3 years of experience in the area of hurricane and tropical cyclone (TC) modeling.


    Demonstrated knowledge, skills, and abilities in at least five of the following areas:

    • Advanced knowledge of physics packages applicable to tropical systems.
    • Advanced knowledge of tropical meteorology and in particular TCs.
    • Knowledge of the physical and mathematical basis of geophysical modeling (atmospheric and/or oceanic) and experience running advanced numerical weather prediction (NWP) models.
    • Experience in high-resolution model development in various infrastructures like WRF and ESMF.
    • Experience working in a UNIX environment with advanced scripting languages (e.g., Perl, ksh, Python, Ruby, etc.).
    • Extensive practical application of computing languages such as FORTRAN and C, working with geophysical data formats (NetCDF, GRIB etc.), and graphical display programs such as GRADS, GEMPAK, MATLAB, IDL, etc.
    • Experience in model testing and evaluation and/or knowledge of objective verification principles.
    • Demonstrated skill in communicating effectively with scientists of diverse backgrounds on technical details of the work plan and present results accurately and clearly in both oral and written form.
    • Ability to work independently and in a team environment on complex problems.
    • Demonstrated skill in performing tasks requiring organization and an attention to detail.


    Desired skills:

    • Familiarity with advanced TC physical parameterizations applicable at high (1-3 km) resolutions.
    • Familiarity with the POM and/or HYCOM ocean models, or their equivalents.
    • Experience developing and testing numerical environmental prediction codes in a high-performance computing environment
    • Familiarity with operational NWP and/or an operational forecasting environment.
