ADAS analyses incorporate a dense network of local observing systems located within east central Florida, supporting the United States space program. These include: 44 wind towers, five 915 MHz boundary layer Doppler wind profilers and a 50 MHz wind profiler. In addition other data sets include: level II radial velocity and reflectivity information from several Florida Weather Surveillance Radar-1988 Doppler (WSR-88D) sites, GOES-12 visible and infrared satellite imagery, METAR surface observations, buoy data, Florida Automated Weather Network observations, Automatic Position Reporting Station (amateur radio) observations and aircraft flight level data.
ADAS analyses with a horizontal resolution of 4 km are produced every 15 minutes and ported to the Advanced Weather Interactive Processing System (AWIPS). These high resolution diagnostics assist forecasters in preparing routine fire weather forecasts as well as specialized fire weather spot forecasts in the instance of wildfire or prescribed burns. A limited number of ADAS graphics are also posted to the NWS MLB web site for use by field fire weather specialists and land management personnel at the local, state and federal levels.
Recently, the ARPS mesoscale forecast model was implemented. ARPS is cycled with the ADAS analyses to produce high resolution prognostics out 9 to 12 hours. This mesoscale model provides fine temporal and spatial resolution guidance to the NWS meteorologist. ARPS forecasts have demonstrated the ability to provide accurate guidance for the preparation of routine fire weather products, and on demand spot forecasts. Key parameters to the land management community (ie. moisture and wind information) can be monitored in real time with ADAS and predicted within 12 hours using ARPS. The depiction and forecast of mesoscale features such as sea breeze onset and progression, as well as the evolution of thunderstorm outflow boundaries can be obtained. The ARPS model has shown promise as an additional tool to forecast the timing and placement of thunderstorm activity critical for safe wildland fire fighting or to conduct effective prescribed burns.
