Lead Story: Hierarchical Model Development and Single Column Models
Summer | Earth system models connect the atmosphere, ocean, and land, and depend on proper representations of dynamics and physics, initial conditions, and interactions of these processes to predict future conditions. Standard meteorological variables are used to validate typical numerical weather prediction models but are gross measures of these countless interactions and limit their usefulness for guiding model improvement. Some fraction of error in these metrics can be the result of specific physical parameterizations, but it can… Read More
Did you know?: The Next Generation Global Prediction System
Summer 2018 | The Next Generation Global Prediction System (NGGPS) multi-year Strategic Implementation Plan (SIP) connects federal and academic experts in the numerical weather prediction community to support the end-to-end functionality of the National Centers for Environmental Prediction (NCEP) Production Suite. The goal of the SIP is to help evolve the NGGPS into a Unified Forecast System (UFS) for operations and research. The SIP governance includes UFS Working Groups who represent the essential science, technical, and design… Read More
Director's Corner: NOAA Embraces Community Modeling to Advance Weather Prediction
Brian Gross, Acting Director EMC
Summer 2018 | NOAA and the National Weather Service (NWS) are embarking on a new strategy of community engagement for developing the numerical weather prediction models that provide NWS forecasters with the best possible guidance. By engaging the broader numerical modeling community, NWS will leverage the vast modeling expertise that resides therein, since each model developer offers a unique perspective about modeling challenges and possible solutions.
Bridges to Operations: Tests Conducted at DTC Lead to Operational Implementation of Innovations in Physics and Data Assimilation in HWRF
Summer 2018 | The Hurricane Weather Research and Forecast system (HWRF) is one of NOAA’s operational models used to predict the track, intensity, and structure of tropical cyclones. Each winter, scientists at NOAA’s Environmental Modeling Center (EMC), the Developmental Testbed Center (DTC), and NOAA’s Hurricane Research Division (HRD) perform testing and evaluation (T&E) on possible changes to the HWRF physics schemes, dynamic core, and data assimilation system that have the potential to improve HWRF predictions. Many of these… Read More
Visitors: Impact of Vertical Advection Schemes of the Hydrometeors on the Simulated Hurricane Structure and Intensity
Visitor: Shaowu Bao
Summer 2018 | Advection is a computationally expensive process in Numerical Weather Prediction (NWP) models. Therefore, time-sensitive operational forecast models sometimes sum up the hydrometeors, including cloud water, rainwater, ice and snow, prior to calling the advection scheme. For this configuration, the model only needs to calculate the advection of the total condensate. However, the impact of such a time-saving technique has not been systematically evaluated. With the release of HWRF 3.9a, a version of the operational HWRF… Read More
Community Connections: 2018 DTC Community Unified Forecast System Test Plans and Metrics Workshop
July 30 - August 1, 2018
Summer 2018 | The 2018 DTC Community Unified Forecast System Test Plan and Metrics Workshop was held at NOAA’s National Center for Weather and Climate Prediction (NCEP) on July 30 - August 1, 2018. The major goal of this workshop was to work towards a community test plan with common validation and verification metrics for the emerging Unified Forecast System (UFS). The plan will serve as a guide for the Numerical Weather Prediction (NWP) community for testing and evaluating new developments for the UFS models and components by… Read More
