John Kenneth Galbraith: convential wisdom
(The Affluent Society 1958)
“We associate truth with convenience, with what most closely accords with self-interest and personal well-being or promises best to avoid awkward effort or unwelcome dislocation of life. We also find highly acceptable what contributes most to self-esteem.”
Economic and social behavior, are complex, and to comprehend their character is mentally tiring. Therefore we adhere, as through to a raft, to those ideas which represent our understanding.”

convential wisdom – weather risks?
Basis for a risk analysis:
which groups are familiar with these risks:
Thunderstorms / floodings / storms / heat waves . . . .
tourists local population professionals (mountain guides, civil protection)

What and how should warnings be?
Warnings often fail to reach the people concerned
Reactions to warnings are not appropriate

What and how should warnings be?
Warnings often fail to reach the people concerned
distribution too low due to technical & organisational handicaps false alarm rate too high unclear systems (danger levels)
Reactions to warnings are not appropriate

What and how should warnings be?
Warnings often fail to reach the people concerned
unclear systems (services involved, danger levels) false alarm rate too high distribution too low due to technical & organisational handicaps
Reactions to warnings are not appropriate no emotional impact no clear advice no „know how“ about the consequences of extreme situations

Why and how should Weather services cooperate?
Fractioned producers / users in Europe and the Alps
unproportional high number of user live in boarder aereas
and hear warnings from neighbouring services
Coordinated warnings reduce the FAR and increase the POD
Commonly used warning systems draw more public attention
Communities in certain areas (like the Alps) develop strong
common sense about natural dangers (conventional wisdom)

What could METEORISK contribute?
• Homogenisation of forecasting work (warning levels etc.)
• Seminars and real time exchange of forecaster Know How
• Densification of observation network
• Common interpretation of model output
• Improved information of civil protection authorities
• Improved information of the public

• Answers
• METEORISK brought more attention to individual weather services and the meteorological community
• links to NMS proved to be succesful
• homogenized individual informations for different user groups were feasible
