  1. Societal Benefits of Winds Mission Ken Miller Mitretek Systems February 8, 2007

  2. National Research Council Vision Statement 1 “A healthy, secure, prosperous and sustainable society for all people on Earth” “Understanding the … planet …, how it supports life, and how human activities affect its ability to do so … is one of the greatest intellectual challenges facing humanity...” NRC (April 2005)

  3. Societal Benefits from Improved Weather Forecasts Using Lidar Winds CivilianMilitary Hurricane Track Forecast Ground, air & sea operations Agriculture Weapons Delivery Transportation Satellite launch Energy Aerial Refueling Homeland Security Dispersion Forecasts for Air Quality Forecast Nuclear, Biological, Recreation & Chemical Release Science Climate Change Issues Circulation H20, trace gases, aerosol, heat transport Carbon cycle Energy cycle ImprovedOperational Weather Forecasts

  4. Quantifiable Economic Benefits • Recent estimates for Decadal Survey, ESTO study, Lidar Winds white paper • Based on 1995, 1998 estimates (Cordes)2,3 • Key assumptions • Seem conservative • Hard to validate • Purpose • Update estimates • Added a benefit area • Increased from $228 M to $807 M / yr • Compared with estimates from other programs

  5. Findings • Benefits greater than in 1995 • Fuel costs • Coastal population • Property values • GDP growth • Inflation • Added offshore drilling rig benefits • Magnitudes in line with other case studies • Additional benefits could be included • Recommend more study of assumptions

  6. US Economy Affected by Weather • 2005 GDP ~ $12.5 Trillion • Percent of GDP affected by weather17 • Nearly 30% directly or indirectly ($3.75 Trillion) • About 10% directly ($1.25 Trillion) • Mission benefits large vs. cost

  7. Benefits Reviewed • Cordes Study2,3 • Quantified $ • Reduce hurricane over-warnings • Reduce hurricane preventable damage and business interruption • Save aviation fuel using wind in routing • General forecast improvement • Not $ - Loss of life and limb • Considine et al Study12 • Off-shore drilling rig decision optimization

  8. Hurricanes: Loss of Life and Limb11 • Not quantified here • Before Katrina, Red Cross estimated 25K to 100K deaths in a New Orleans worst case • Death rate for hurricanes with > $1 B property damage (20 yr avg to 2005) • All 128 / yr • Excluding Katrina, Andrew 34 / yr • “…late 20th century forecasting prevents 90% of hurricane-related mortality that would occur with techniques used in the 1950s”

  9. Hurricane Over-Warning Savings10,11 • Evacuation cost: popular estimate $1 M / mile • Regional dependence • Could exceed $50M / mile in some areas • Much less in other areas • Hurricane Floyd (1999) evacuation cost rivaled damage cost 9

  10. Reduce Hurricane Overwarning • Statistics 1995 2 2005 11 • Typical warning 341 miles 300- 400 • Affected coast 124 miles 100 • Overwarning 217 miles 200- 300 • Benefits • Cost / mile $145 K $ 1 M • Over-warn cost / landfall $ 32 M • Reduce over-warning/landfall $ 5.4 M (17%*) $50 M (50 miles) • x 2 landfalls / yr $ 11 M100 M** • Or scale 1995 to $1M / mile $ 75 M 2005 Evacuation Avoidance: $75 to 100 M/yr * Storm climatology and simulations for global 3D winds in NWP ** Ref 11, better forecasts, not necessarily wind measurement alone

  11. Direct Hurricane Property Damage 11 • Much not preventable • Hard to demonstrate reduction • Probably improves over time • Growth & property values increase losses • “…no discernable trend from better forecasts or more effective mitigation measures”

  12. Direct Property Damage Savings (1995)2 • 13 yr to 1995 avg damage • Selected “typical” storms w/o Andrew = $1.2 B / yr • Assumed • 15% preventable with sufficient warning • 17% forecast improvement with winds vs. 1995 24 hr • Total 15% x 17% = 2.5% • Reduction, typical hurricanes = $30 M / yr

  13. Update Direct Damage • For > $B storms • 20 yr avg to 2005 (2005 $) • About 1 landfall / yr > $1B • $7.1 B / yr less Andrew, Katrina • $15.7 B / yr counting Andrew, Katrina

  14. Update Direct Damage (concluded) • Using the lower number • $7.1 B / yr without Andrew, Katrina • Account for lesser hurricanes 22 • Divide by .83 • Total = $8.5 B / yr • Reduce preventable losses 2.5% 2 • 2005 Savings Estimate = $212 M / yr

  15. Off-shore Drilling Rigs • Not in Cordes study • Gulf Rigs 12 • Need hurricane track/intensity • Optimize operating decisions: continue, evacuate, stop production • Estimated value of 24 hour forecast • Perfect $239 M / yr • Imperfect $ 10 M / yr • Assume 17% improvement2 x ($239 M-$10 M) • Benefit = $39 M / yr

  16. General Forecasting • Winds improve accuracy and lead times • Forecasts impact the economy • How much?

  17. Some Industries Affected by Weather16, 18

  18. General Forecasting (1995)2 • Chapman study 20 • Estimated gains from maximum forecast improvement from NWS modernization • $1.2 B / year in 1992 • Cordes2 • Assumed winds provide 5% of max • $60 M / yr ($1992)

  19. Scale 1995 General Forecasting Estimate by GDP • 1992 • GDP = 5.6 Trillion 1992$ • Benefit was $60M • 0.0011 % of GDP • 2005 GDP estimate = $12.5 Trillion • 2005 benefit scales to > $137 M / yr

  20. Forecast Improvements Example 1: Households • Household benefit estimates for better forecasts • $1.7 B / yr (2003) 13 • $1.87 B / yr (2005) 14 • This doesn’t include industry benefits

  21. Forecast BenefitsExample 2: ENSO 17 • El Nino Southern Oscillation (ENSO) savings estimate • U.S. agriculture $200-300 M • U.S. corn storage $ 10- 25 M • NW US salmon fishery $ 1 M • Total $211-326 M • Can winds help?

  22. Forecast Benefits Example 3:Est. Marginal GOES-R Benefits15 $M / yr Agriculture • Avoided irrigation costs15 41 • Orchard frost mitigation 9 Transportation • Flight delays 41 • Trucking 28 – 56 Recreational Boating 86 - 130 Energy Utilities 486 - 507 Total of Case Studies 691 - 784

  23. Conclusions from General Forecasting Examples • Big benefits: examples = $1191 to 1428 M / yr • Is our $137 M “in the ballpark” or low? • Can add important benefits to list

  24. U.S. Airlines Fuel Savings • User preferred routing • Critical capability for FAA Next Generation Air Transportation System (NGATS) • Wind optimal routing can save fuel • Benefits: economic, environmental, energy security

  25. U.S. Airlines Fuel: 1995 Estimate 2 • Background • Fuel consumption effects • 50 knot wind ~ 11% fuel impact (FAA, early 1980s) • Haul extra fuel for unknown wind conditions • Real time vs. NWS forecast winds cut flight time 4.2% (simulation early 1980s) • Cordes2 lidar fuel savings estimates • 0.5% domestic • 1.0% international, less wind information available 2006 Savings = $107 M / yr (1994$)

  26. Update U.S. Airlines Fuel • 2006 (annualized Jan - Nov data)5 • 19.3 billion gallons @ average $1.972 / gal = $38 B • 72% for domestic flight, 28% international • Estimated savings with wind data • Domestic $137 M • International $106 M 2006 US Airlines Savings Estimate= $243 M

  27. U.S. Military Aviation Fuel for 2006 (Cordes 1998)3 Military Aviation Savings ~ $20 M (1994$)

  28. Military Aviation – More Recent Numbers21 • AF jet fuel usage 2.6 B gallons / year • 53% over continental US • Cost • ~ $2.40 / gal • vs. $0.63 in 1995 study • Transport to plane $1.30 / gal

  29. Military Aviation Update* * Basis is 2.6 B gallons / yr for AF, $2.40 / gal for fuel, $1.30 / gal for transport to plane, estimated Navy usage using ratio from Ref 3.

  30. 2006 Annual Benefits Estimates ($M)

  31. Conclusions • Dollar benefit estimates have increased • Fuel costs • Increased coastal population and property values • Growing GDP • Added offshore drilling rig benefits • Magnitudes seem in line with other weather case studies • Assumptions should be reviewed • Significant benefit areas may not be included yet

  36. Weather in Economic Decision Making 2 Simple Decision Model P = Probability of adverse weather event L = Loss from adverse weather event S = Savings by preventive action (given adverse event) C = Cost of action Cost = 0 if no adverse event Then: Expected loss without action = PL Expected loss with action = P(L-S) + C If PS > C, it is rational to act

  37. Better Forecasts MakeBetter Decisions • P is the weather forecast (neglecting the complexities) • If less uncertainty in P • People use it more • Better economic decisions • Evacuation decisions will be conservative since loss of life is a factor
