2018 Hurricane WRF (HWRF) Tutorial

Date: Jan 23-25, 2018
Location: NOAA Center for Weather and Climate Prediction in College Park, MD

A Hurricane WRF Tutorial will be held on Jan. 23-25, 2018 at the NOAA Center for Weather and Climate Prediction (NCWCP) in College Park, MD. This 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.


The HWRF tutorial will not provide basic training on numerical weather prediction (NWP) or on the Weather Research and Forecasting (WRF) model. Therefore, it is recommended that all participants have a basic understanding of NWP and experience using WRF. We suggest that all participants unfamiliar with WRF familiarize themselves with the online WRF tutorial as well as the Gridpoint Statistical Interpolation (GSI) data assimilation online tutorial prior to attending the HWRF tutorial.

Participants should bring a laptop computer with a ssh client with x11 forwarding. The laptop also needs a USB port for the token to access the National Center for Atmospheric Research (NCAR)'s supercomputer, Cheyenne. If this is a limitation, please contact

Available Spaces

Due to the constraints of physical space and computers, registration for the tutorial with lecture and practical sessions will be limited to 40 participants.

Registration & Payment

There is a registration fee associated with the HWRF tutorial to cover necessary material costs and other expenses.

  • Full Tutorial (both lecture and practical sessions): $175 (includes supplemental materials and morning and afternoon refreshments). Please bring a personal laptop for the practical sessions.
  • NCWCP residents (with NOAA CAC cards): No registration fee will be charged, but supplemental materials and refreshments will not be provided - an option to order refreshments will be provided separately.

Registration fees must be paid by credit card. You will receive a confirmation that you have registered, and your credit card will be charged immediately. No refunds for cancellations will be given after December 22, 2017.

Given time constraints for the lunch breaks, information on how to order a lunch from the cafeteria will be provided to all registrants in early January.

If you have any questions or are unable to register, please e-mail:

Summary of Important Dates

  • 5 October 2017: Registration opens.
