  3. Define NCEP

  4. NCEP Mission Statement NCEP delivers national and global weather, climate, ocean and water guidance, forecasts, warnings, and analyses to its NWS Partners and External User Communities. These products and services respond to user needs to protect life and property, enhance the nation’s economy, and support the nation’s environmental information database. NCEP Central Operations Climate Prediction Center Environmental Modeling Center Hydrometeorological Prediction Center Ocean Prediction Center Aviation Weather Center Space Environment Center Tropical Prediction Center Storm Prediction Center

  5. NCEP’s Future Location New Location NOAA Center for Weather and Climate Prediction UMD Research Park, College Park (Early FY08) Current Location NOAA Science Center World Weather Building Camp Springs

Severe Storm Outlooks Fire Weather Outlooks Winter Weather Guidance Quantitative Precipitation Forecasts to 5 days Weather Forecasts to Day 7 Day 8-14 Critical Weather Outlooks Marine Weather Discussions Model Discussions Severe Weather Watches Marine High Seas Forecasts Hurricane Watches and Warnings Aviation Warnings (Convective, Turbulence, Icing) Climate Forecasts (Weekly to Seasonal to Interannual) Solar Monitoring – geomagnetic storm forecasts What Does NCEP Do? Guidance to Support WFO/RFC National Products • Model Development, Implementation and Applications for Global and RRegional Weather, Climate, Oceans and now Space Weather • International Partnerships in Ensemble Forecasts • Data Assimilation including the Joint Center for Satellite Data Assimilation • Super Computer, Workstation and Network Operations

  9. NCEP’s Future is Built Upon: • Climate-Weather-Water-Land-Chemistry Linkages; for example • Seasonal Hurricane Outlooks & Extratropical Storm patterns • Meteorological-Hydrological forecasts • Ocean and atmosphere coupled forecasts • Atmosphere-Land Processes coupled forecasts • Relationship of solar activity on service provision and climate fluctuations • Ozone forecasts by combining air chemistry and operational models • “Seamless Suite” of products through a collaborative approach • Extension of predictability of Weather and Climate (from snowstorms to ENSO); Improve the forecasts of Extreme Events • Community Model Approach – Common Model Infrastructure • Addressing forecast uncertainty – Ensemble modeling • Test Beds in each Service Center • U.S.Weather Research Program THORPEX: International Polar Year – 07/08 GEOSS

  10. Student Employment Programs at NOAA • Student Educational Experience Program (SEEP) • Student Career Experience Program (SCEP) - SCEP is a program that provides experience that is directly related to the student’s educational program and career goals. SCEP replaces the Cooperative Education Program (COOP). Agreements are made with an accredited school combined with periods of career-related work in a Federal agency. Students earn federal benefits. Students interested in applying for a SCEP position should contact the Cooperative Education Coordinator at their school. • Student Temporary Employment Programs (STEP) - Does not have to be in your career field. The position is not to exceed one year with incremental extensions. It is great for career exploration.

  11. Student Employment Programs at NOAA • NOAA Faculty and Student Intern Research Program administered by the Oak Ridge Institute for Science and Education (ORISE): • Ten week faculty and student intern research program. Primary focus to provide work experience to faculty, graduate and undergraduate students under represented in mission-related occupations. FTE neutral. • NOAA’s Educational Partnership Program • Sponsored by the NOAA Diversity office and funded by Congress. Students are recruited from Minority Serving Institutes. Salary and graduate school tuition are paid for while attending school. • Workforce Recruitment Program • The WRP is a resource for federal agencies nationwide to provide employment opportunities for qualified students with disabilities. FTE neutral. • For more information on all programs • http://www.weather.gov/eeo/StudentResearchOpportunities.htm

  12. NCEP Employment Situation • Employment situation – FY04 • Total of 375 Civil Servants; 146 contractors; 18 visitors • Currently have 5 Student Interns (SCEP/STEP) • During the last 12 months • 32 CS vacancies; 5 SCEPs; • Hired 22 contractors & visiting scientists • 20 Summer/Student Program Hires (ORISE, GoHFAS, NOAA Educational Partnership Programs) • Projected growth through ’08: 50 – 60 (contractors/visiting scientists/postdocs)
