  1. Aviation Weather Center Convective Weather Information In the NWS

  2. CCFP • Intuitive Graphics have been successful • Misinterpreted and misapplication • Solid yellows, oranges, and reds • No color change showing confidence • Improved Interpretation and application • Confidence: Blue and Grey • Coverage: Stippling, stripes, and solids

  3. CCFP • Before: Personal Preference-based Application • 2006: Systematic Application through Airspace Flow Programs in the Northeast • Need changes for FY07

  4. Use of Weather Info in ARTCC

  5. ARTCC Impacted Sector TDA PACE Example

  6. Comment • “Too Many Weather Products. Need Consolidation of Products.”

  8. Let’s understand difference between ‘product’ and ‘display’. • A product is the information from which the display is created: • Gridded data to create NCWD • BUFR data to create NCWF 1 hour forecast polygons or CCFP • Created by a Weather Provider

  9. Let’s understand difference between ‘product’ and ‘display’. • Product and ‘hard copy’ used to be the same. No longer. • A display is a visualization of the digital product, and more… • A display turns digital products into color and line texture • A display can write disclaimers that are not in the digital product. • A display can show the alphanumeric information contained in an object, and choose where to place this label. • A display can create a single picture with TWO products (i.e., NCWD & NCWF, CIP Severity filtered by probability > 50%) • A display can animate digital products (NCWF-2, CIWS

  10. Let’s understand difference between ‘product’ and ‘display’. • A display can integrate digital products with non-meteorological information. • A display can choose to show only information pertinent to the decision maker. • A display can turn high resolution data into categories (of the decision-maker’s choosing). • A display can allow users to interact and show areas and features the user wants from many products (Flight Path Tool) • Displays can add confidence statistics based on verifying past products. • Displays will be built by government and private entities (not necessarily the weather provider). ADDS is only the first of many new sophisticated displays to be developed.

  11. TEXT/ VOICE Digital, Gridded, Probabilistic Convective Products 0-24 hours Deterministic Graphic Suite Displays/ Integration Displays Probabilistic Graphic Suite Decision Tools Convective TDAs From One Product, Many Displays Systems

  12. Some Things to Overcome • Quality of the Gridded, Digital Products • Until then, human forecaster produced or enhanced. Gridded forecasts will be made official as they get meet needed criteria. • Distribution • Pipes need to be big enough • Proper presentation for each decision • Many types of decision displays • Displays and critical criteria need to be determined. • Hardware • Grids to Text

  13. Summary • Many products exist today because of the variety of uses for which they are designed. • Some day a single convective 4-D forecast will be the basis for many, many, displays and tools tailored to their use. • Process step by step as quality increases sufficiently. We’ll see results for evaluation. • Hide till we’re done?
