Terrorism and Hazardous Weather Events: What have they in common? 7th Annual CRHNet Symposium Fredericton, NB 27-29 October 2010 Jacques Descurieux Meteorological Service of Canada Page 1 – July-6-15 INTELLIGENCE ANALYSIS COMMUNICATIONs Why Terrorism • "Hurricane Katrina: framing the issue – A weapon of mass destruction without criminal dimension” • A. Thaad, Admiral USCG (Ret.) • Floods pose “as great a threat as terrorism” • Sir Michael Pitt • 5000 passengers taken “hostage” • YVR 2009 • Montreal “roof collapses” March 2008 • YVR December 20/21 2008 • Katrina • Xynthia • Montreal “heat wave” August 2010 Intelligence? Intelligence = Information Analysis? Analysis = Knowledge Chronology of the Montreal Case Collapsing roofs cases Associated Risk Factors Weather Elements Event Type Direct Impacts Risk Perception Varied Precip.

Yes Vulnerability? • 50 000 flat roofs in Montreal as a result of age and ensuing reduced structural integrity. Qualitative Comparative Analysis (QCA): • Summarizing data (data exploration and typology) • Checking the coherence of data (systematic cross case comparisons) • Corroborate existing theories or assumptions • Elaborate new theories or assumptions • Test new theories or assumptions What is “QCA”? • A small to intermediate “N” (2 to 10 and 10 to 100) cases comparisons and analytical tool • “Qualitative” because it is a case-based technique • Introduces the concept of “conjunctural (configurational) causation” Basic Glossary • Determinant or Condition: an explanatory variable that may affect the outcome. Determinants can be “necessary” and/or “sufficient” • Outcome: a variable to be explained by the determinants or conditions • Boolean minimization: Reducing complex “expressions” into minimal formula Associated Risk Factors Weather Elements KATRINA (New Orleans) XYNTHIA (SW France) Precip.

CQA risk communication and response table: Risk Communication Cognitive Determinants of Response Was the message: Did the message tell: Events and date Type of Hazardous weather Understandable ? Usable? Actionable? What could happen? How will this evolve? How will it affect me? How can I cope with this weather hazard?

Communications? Communication = Knowledge Sharing or Knowledge Transfer MSC CMAC NavCanada MSC PSPC YVR Ground Ops Airlines YVR De-Icing Weather Warning YVR Snow removal Fig. 1: Simplified weather warning “value chains” Based on the Dec. 20, 2008 Snow event in YVR Airlines Airport Station Airlines National Dispatch/Ops AIRPORT AIRPORT NavCan Ground Contractors Ground Ops Airport Ops NavCan Meteorological Private Sector National Ops WPM Fig. 2: A Simple Aviation “Value Network”: CMAC TAF – TAF+ VCMAC DISSEMINATION Special Weather Bull Warnings Regional SPC It is not about the communication channel. It is the message that matters! Socio-contextual and cognitive determinants of individual response to threat: Socio-contextual factors: • Perceived preparedness • Trust Responses: • Information/knowledge gathering Cognitive factors: • What could happen? • Preparedness • Risk avoidance • How will it evolve? • How will it affect me? • How can I cope? Adapted and simplified from: Lee, J.E. and Lemyre, L (2009) Lee, J.E. and al. (2009) Preliminary Findings • Individuals are more likely to respond to a warning if it includes the 4 cognitive determinants of response to threat. • Failure to include even one element of any of the cognitive determinants may be sufficient to result in an inappropriate response to a specific threat. Successful preparedness is about INFORMATION ANALYSIS COMMUNICATION
