  1. Jalen Heyward Changes in Storm Intensity in North Carolina

  2. Introduction to Storms • Thunder storm- storm that produce lightning and thunder • 2 major components precipitation and wind speed/ gusts • Important for safety matters and agriculture How has storm intensity changed throughout the years in North Carolina?

  3. Motivation • $485 billion in damage from storms in General. (National Weather Service, 2011) • Storm intensity is important to know for our economy. • Hypothesis: If storm intensity changed through out the year then the intensity would increase

  4. 7 Weather Stations • Stanly County Airport( KVUJ) • Upper Piedmont Research stn (Reidsville, REID) • Upper Mountain ResearchStn (Laurel springs, LAUR) • BearwallowMountain (Hendersonville, BEAR) • Central Crops Research station(Clayton, CLAY) • Pamlico Aquaculture Field Lab (Aurora, AURO) • Border Belt Tobacco Res stn( Whiteville, WHIT)

  5. Materials • Ten years of data • maximum wind speed • maximum wind Gust • total precipitation • maximum precipitation

  6. Procedure • Collected data from the different stations • Convert hourly data to daily data • Maximum wind speed, • Maximum wind gust, • maximum precipitation, • Total precipitation. • Graphed each data sets in time • Calculated coefficient of variance( R2), trend

  7. Border Belt Tobacco Research Station (Whiteville) Trend line decreases

  8. Border Belt Tobacco Res station (Whiteville) Trend line slightly increases

  9. Border Belt Tobacco Res station (Whiteville) Trend Line 0 slope

  10. Border Belt Tobacco Res station (Whiteville) Trend line slightly decreases

  11. Bear wallow Mountain

  12. Pamlico aquaculture field lab Trend line slightly decreases

  13. Summary of slopes

  14. Conclusion • Maximum Windspeed= Trend line Decrease • Maximum Precipitation= Trendline Increase • Total precipitation= Trendline decrease • Maximum Wind gust= Trend line increase • Neither increasing or decreasing storm intensity. • Results don’t support hypothesis.

  15. Future Work • Data = variable • How Much money was involved? • Look at surface analysis • Reports of tornadoes, wind, and Hail • Looking at a much longer period

  16. Acknowledgements • Thank you to the NC State Climate office • Thank you Adrienne and the other mentors for mentoring me.
