Experimentation and Development of Physical Parameterizations for Numerical Weather Prediction Using a Single-Column Model and the Common Community Physics Package (CCPP)

October 11, 2019

The AMS Short Course on Experimentation and Development of Physical Parameterizations for Numerical Weather Prediction Using a single-column model and the Common Community Physics Package (CCPP)  will be held on 12 January 2020 preceding the 100th AMS Annual Meeting in Boston, MA. Preliminary programs, registration, hotel, and general information will be posted on the AMS Web site.    

The goal of this course is to familiarize participants with new tools for experimentation and development of physical parameterizations for Numerical Weather Prediction (NWP). Students will be exposed to the physics suites available through the Common Community Physics Package (CCPP), a library of physical parameterizations that is in use with NOAA’s Unified Forecast System. Supported suites include the operational GFS, the suite under development for the next operational GFS implementation, the suite used by the Rapid Refresh and High-Resolution Rapid Refresh (RAP/HRRR) models, and a suite developed under the auspices of a NOAA Climate Process Team.

In this course, the CCPP will be taught in conjunction with the Global Model Test Bed (GMTB) single-column model, a simplified framework that enables experimentation in a controlled setting. Various research cases will be provided as forcing datasets for the single-column model, all originating from experimental field campaigns focused on specific meteorological phenomena, such as a DOE-ARM LASSO case focused on shallow convection and a TWP-ICE case focused on maritime deep convection. In addition to its conceptual simplicity, the single-column model is not computationally demanding and can be executed on computers readily available to graduate students or in the cloud. The CCPP and the GMTB single-column model are publicly released and supported community codes (https://dtcenter.org/gmtb/users/ccpp/).

Instructors include Developmental Testbed Center subject matter experts from NOAA Global Systems Division and the National Center for Atmospheric Research.

Participants are expected to bring their own laptops to be able to participate in the hands-on exercises. Laptops must enable ssh connection. In order to display the results, students must either have the ability to receive data through scp or have X windows support configured.

For more information please contact Ligia Bernardet at the Global Model Test Bed helpdesk at gmtb-help@ucar.edu.

Short Course on Containers and Cloud Computing at AMS Annual - 12 Jan 2020

October 10, 2019

The Developmental Testbed Center (DTC) will host a short course on Integrating NWP System Components Using Container Technology and Cloud Services on 12 January 2020 preceding the 100th AMS Annual Meeting in Boston, Massachusetts. The goal of this course is to raise awareness about tools and facilities available to the community for testing and evaluating Numerical Weather Prediction (NWP) innovations, including the emerging set of software tools in reusable containers and cloud computing resources, through hands-on learning. 

While this course may appeal to a wide-reaching audience, this information may be particularly useful to undergraduate and graduate students interested in learning more about NWP and to university faculty that may find software containers and cloud computing to be useful teaching tools to add to their course curriculum. For more information, please see: https://annual.ametsoc.org/index.cfm/2020/programs/short-courses-workshops/integrating-nwp-system-components-using-container-technology-and-cloud-services/

 

2018 DTC Community Unified Forecast System Test Plan and Metrics Workshop

April 30, 2018

The Developmental Testbed Center (DTC) is pleased to announce an upcoming community workshop on Numerical Weather Prediction test plan and metrics for model validation and verification.

Now available: Agenda | Registration | Logistics

The workshop, to take place at the NCWCP in College Park, MD, will be held for two and a half days prior to the NGGPS Strategic Implementation Planning (SIP) meeting at the same location. The major goal of this workshop is to develop a community test plan with common validation and verification metrics for the emerging Unified Forecast System (UFS). When complete, the plan will serve as a guide for the NWP community for testing and validating new developments for the UFS models and components, and for verifying the UFS for both historical and real-time forecasts using observations and analyses, through standardized hierarchical testing. While metrics for all spatial and temporal scales for NWP models will be open for discussion at the workshop, emerging topics such as the verification of Convective Allowing Models, coupled earth system models, and ensemble systems will be emphasized.

The full two days of the workshop (July 30th - July 31st) will utilize mornings for participant presentations and short discussion periods, with the afternoons focusing on editing plan documents in various topic-based breakout sessions. Participants are requested to bring a laptop or tablet to assist in the real-time development of planning documents during the breakout sessions. A wrap-up session will be held on the final morning (August 1st). NGGPS Strategic Implementation Planning (SIP) meeting attendees are encouraged to participate in the Test Plan and Metrics wrap-up session prior to their meeting starting the afternoon of August 1st.

2018 Hurricane WRF Tutorial

Autumn 2017

The DTC is pleased to announce that registration is now open for the 2018 Hurricane WRF (HWRF) tutorial to be held 23–25 January 2018 at the NOAA Center for Weather and Climate Prediction (NCWCP) in College Park, MD. Registration, a draft agenda, and information about hotel accommodations and other logistics can be found on our tutorial website:

2018 HWRF tutorial

The HWRF tutorial will be a three-day event organized by the Developmental Testbed Center (DTC) and by the NOAA Environmental Modeling Center (EMC). The Hurricane Weather Research and Forecast system (HWRF) is a coupled atmosphere-ocean model suitable for tropical cyclone (TC) research and forecasting in all Northern and Southern Hemisphere ocean basins.

Tutorial participants can expect to hear lectures on all aspects of HWRF, including model physics and dynamics, nesting, initialization, coupling with the ocean, postprocessing, and vortex tracking. Additionally, enrichment lectures on HWRF's multistorm capability, TC verification, HWRF ensemble system, and NCEP's future plans for TC numerical weather prediction will be presented. Practical sessions will give tutorial participants hands-on experience in running HWRF.

We look forward to seeing you in College Park. If you have any questions, please do not hesitate to contact:

WORKSHOPS, TUTORIALS, EVENTS

Physics Workshop The DTC and NOAA will convene a workshop entitled ‘Parameterization of moist process for next-generation numerical weather prediction models’ on January 27-29 2015 at the NOAA Center for Weather and Climate Prediction in College Park, MD.

The workshop is intended to stimulate the development of moist process parameterization for the Next- Generation Global Prediction System (NGGPS) and similar global models at scales and resolutions ranging from synoptic- to convection-permitting. The theme of the workshop will also be highly relevant to current and future generation regional and mesoscale models. Observational, modeling and theoretical perspectives will be addressed. Details will be available at http://www.dtcenter.org/events/workshops15/moist_phys/
