Physical Scientist and Ensemble Modeler Atmospheric River Forecasting

Overview

Lynker is seeking a talented Physical Scientist and Ensemble Modeler for Atmospheric River Forecasting to support the Environmental Modeling Center (EMC) of the National Centers for Environmental Prediction (NCEP) in research and development related to the Unified Forecast System (UFS) based Atmospheric River Forecasting System. The position supports the Water in the West initiative by developing and implementing the On-Demand Regional Atmospheric River Ensemble Forecast System (AR-EFS) within the UFS framework.

The role focuses on advancing ensemble-based regional modeling, developing data assimilation and post-processing techniques, and preparing the system for real-time applications and potential transition to NWS operations.

• Design, develop, and implement ensemble-based regional AR-EFS configurations using the UFS framework.
• Develop and test ensemble perturbation methods, multi-physics configurations, and stochastic physics schemes to improve probabilistic AR prediction skill.
• Integrate and evaluate regional data assimilation components using in-situ and satellite observations (e.g., AR Recon data, ASSIST radiances).
• Conduct retrospective and near-real-time ensemble experiments for multiple Atmospheric River (AR) seasons.
• Collaborate with partners (e.g., EMC, WPC, CW3E, and OAR) to refine model configurations and evaluate system performance.
• Support Transition to Operations (T2O) planning with NCEP Central Operations (NCO), ensuring compliance with operational standards and HPC constraints.
• Prepare scientific documentation, technical reports, and peer-reviewed publications summarizing findings and outcomes.

• Advanced degree (M.S. or Ph.D.) in Atmospheric Science, Meteorology, Oceanography, Computer Science, or a related field.
• 5+ years of experience in scientific programming.
• 3+ years of specialized experience in coupled forecast and data assimilation systems.

• Experience in numerical weather prediction (NWP) model development and testing (preferably UFS, FV3, HAFS, or similar).
• Strong background in ensemble forecasting, data assimilation, or stochastic physics.
• Proficiency with high-performance computing (HPC) environments and parallel programming.
• Strong analytical and communication skills; ability to work in collaborative, multi-institutional teams.

• Experience with NOAA operational or experimental modeling systems.
• Familiarity with probabilistic verification metrics and ensemble bias correction methods.
• Experience coordinating transition-to-operations (T2O) or real-time testbed activities.
• Record of peer-reviewed publications in ensemble modeling or atmospheric river prediction.
