The Hurricane Wea<strong>the</strong>r, Research and Forecasting (HWRF) model is one <strong>of</strong> two NOAA<br />
operational regional numerical wea<strong>the</strong>r prediction (NWP) models for tropical cyclones. HWRF<br />
is an important component <strong>of</strong> <strong>the</strong> numerical guidance used at <strong>the</strong> National Hurricane Center for<br />
tropical storm forecasting. For that reason, it is critical that HWRF be continuously improved<br />
and uses state <strong>of</strong> <strong>the</strong> art research and developments in tropical NWP.<br />
The Developmental Testbed Center (DTC – dtcenter.org) has partnered with <strong>the</strong> NOAA National<br />
Centers for Environmental Prediction to work with <strong>the</strong> transfer <strong>of</strong> new technologies onto HWRF.<br />
The DTC is an organization with nodes at NOAA Earth System Research Laboratory and <strong>the</strong><br />
National Center for Atmospheric Research that has as a mission bridging <strong>the</strong> gap between<br />
research and operations in several areas <strong>of</strong> numerical wea<strong>the</strong>r prediction.<br />
The DTC’s work in transferring new technology to HWRF follows two strategies. First, <strong>the</strong> DTC<br />
recognizes that <strong>the</strong> use <strong>of</strong> a single code base between research and operations facilitates <strong>the</strong><br />
exchanges between <strong>the</strong> two groups. Over <strong>the</strong> last year, <strong>the</strong> DTC has worked with NOAA NCEP<br />
to merge <strong>the</strong> components <strong>of</strong> <strong>the</strong> HWRF model that are used operationally onto Community<br />
codes. This work has culminated with <strong>the</strong> transfer <strong>of</strong> a community model for operational<br />
implementation for <strong>the</strong> 2011 hurricane season. Since March 2010, <strong>the</strong> DTC has been providing<br />
code management and user support for HWRF (http://www.dtcenter.org/HurrWRF/users),<br />
having now reached 150 registered users. Our presentation will describe <strong>the</strong> process used to<br />
transfer <strong>the</strong> community model onto operations and <strong>the</strong> support that DTC provides to its users.<br />
The second strategy is to have <strong>the</strong> DTC maintain a functionally equivalent HWRF testing and<br />
evaluation infrastructure in order to assess new developments that have a potential for<br />
operational implementation in <strong>the</strong> short or medium term. We will present results <strong>of</strong> multipleseason<br />
forecasts <strong>of</strong> <strong>the</strong> Community HWRF model and will discuss <strong>the</strong> upcoming evaluations to<br />
be conducted at <strong>the</strong> DTC to test new developments that have a potential for operational<br />
implementation.<br />
