The 29th Conference on Weather Analysis and Forecasting and the 25th Conference on Numerical Weather Prediction Conferences, sponsored by the AMS and organized by the AMS Committee on Weather Anyalsis and Forecasting, was held 4-8 June 2018 at the Grand Hyatt in Denver, CO. 

 29th Conference on Weather Analysis and Forecasting and the 25th Conference on Numerical Weather Prediction Conferences solicited papers and posters from the research and operational weather forecasting community on the following topics:

• Weather Analysis and Forecasting
  • Weather phenomena
    • Winter weather
    • Tropical weather
    • The 2017 Hurricane Season
    • Severe storms
    • Mesoscale meteorology
    • High impact local weather
  • Forecasting techniques
    • Aviation forecasting
    • Hydrologic forecasting
    • Fire weather analysis and forecasting
    • 2017 Wildfires – meteorological aspects
    • Impact of new data types and observational platforms
  • Forecasting tools
    • New applications
    • Satellite applications
    • Quantitative precipitation forecasts
    • Testbed, proving ground, and research-to-operations activities
    • Observational and NWP tools to facilitate decision support services, including social media
    • Results from recent field campaigns: VORTEX-SE, SHOUT, and others.
  • Societal impacts of weather
    • Impacts of extreme weather events on society, economy, and public health
    • Linkages between weather analysis, forecasting, NWP, impact-based decision support services derived from these topics, and continued preparation of NOAA’s “Weather-Ready Nation”
• Numerical Weather Prediction
  • Data assimilation techniques
  • Model development and application
    • Forecast verification methods and performance
    • Updates on global and mesoscale models
    • Improving model performance and efficiency
    • New or improved parameterizations
    • Local application of regional models
    • Regional climate downscaling approaches or short-range climate prediction
  • New ensemble generation or probabilistic-based forecasting techniques

Authors were welcome to submit papers on the full range of topics solicited above, in addition to other cross-cutting applications that blend WAF/NWP topics with other areas of research or applied science.

            An abstract fee of $95 (payable by credit card or purchase order) was required at the time of submission. Please note that some abstracts were not accepted, depending on program constraints, relevance, and merit of subject matter. In such cases the abstract fee was refunded. Authors could indicate their preference for an oral or poster presentation during abstract submission; those authors that presented more than one paper clearly indicated which they prefer for a possible oral presentation. Oral presentation slots were very limited; thus, authors could only request one oral submission, but were welcome to present multiple posters. Authors of accepted presentations were notified via e-mail by late-March 2018. These authors were strongly encouraged to submit an extended abstract (at no extra cost) electronically prior to the start of the conference, but manuscripts were accepted through the electronic submission system through 7 July 2018. Instructions for formatting extended abstracts (PDF format, up to 10 MB in size) were posted on the AMS web site. All abstracts, extended abstracts and presentations are available on the AMS web site at no additional cost.
