To assist in the development and population of NWEFD, Environment Canada has developed an expert system called SCRIBE. When complete, the forecaster runs software that creates text-based forecasts. Environment Canada forecasters manipulate the NWEFD making adjustments to forecast fields based on an analysis of the current state of the atmosphere and model output, including known model biases and trends. The Australian Bureau of Meteorology is in the process of evaluating and developing an implementation plan for database forecasting using the NOAA/NWS National Digital Forecast Database approach.Įnvironment Canada National Weather Element DatabaseĮnvironment Canada has developed the National Weather Element Forecast Database (NWEFD) that is populated with output from NWP models. Digital database forecasting also offers one of the most exciting opportunities to integrate PWS forecast dissemination and service delivery, which most effectively serves the user community.īoth the US National Oceanic and Atmospheric Administration (NOAA)/ National Weather Service and Environment Canada are currently using digital database forecasting technology to produce routine forecasts. The concept of digital database forecasting provides the capability to meet customer/partner demands for more accurate, detailed hydrometeorological forecasts. Traditional NWS text forecast products limit the amount of additional information that can be conveyed to the user community. Internet), National Weather Service (NWS) customers/partners were demanding detailed forecasts in gridded, digital and graphic formats. Over the last decade, technological advances and scientific breakthroughs have allowed NMHSs’ hydrometeorological forecasts and warnings to become much more specific and accurate.Īs computer technology and high-speed dissemination systems evolved (e.g. The process is typically schedule-driven, product-oriented and labour-intensive. maximum/minimum temperature, cloud cover) using numerical weather prediction (NWP) output as guidance. The traditional forecast process employed by most NMHSs involves forecasters producing text-based, sensible, weather-element forecast products (e.g. It will focus on digital database forecasting, next-generation forecast workstations, nowcasting systems and IT systems and applications. This article provides an overview of several key innovations, technological advancements and IT systems/applications which have, or can have, a substantial impact on improving NMHSs’ public weather services and their dissemination and service delivery. Digital database forecasting and next-generation workstations, along with new and emerging Information Technology (IT) systems and applications, offer the opportunity to further enhance and integrate PWS dissemination and service delivery functions. In addition, these innovations can impact NMHS service delivery capabilities. These innovations allow National Meteorological and Hydrometeorological Services (NMHSs) to provide hydrometeorological forecasts and warnings in a variety of formats (graphic, digital) beyond the traditional text products. Internet, wireless communication, digital database forecasting, next-generation workstations, nowcasting systems) have emerged, which provide the opportunity to improve public weather services (PWS). New communication networks and forecast system innovations and technology (e.g.
