Human perception of surface wind, rain and water current: preliminary
experimental findings and discussion about implications for advisories

Masters FJ, Webster GA, Agdas D

Abstract:
Wind-human interaction studies have primarily focused on defining wind
speed thresholds that make daily tasks challenging, uncomfortable or
unsafe, with major emphasis on pedestrian ‘comfort’ criteria in urban
areas. Virtually no research has been carried on human perception of
rain and water current speed and depth. These knowledge gaps led the
authors to conduct a comparative study to characterize human
perception of hazardous agents resulting from severe weather events
(e.g., hurricanes, thunderstorms, flash floods/storm surge).
Seventy-six study participants were subjected to physical simulations
of wind (no rain), wind (with rain), horizontal rainfall (no wind) and
storm surge / flooding (current depth and speed were varied). Two
forms of perception data were collected: estimates of intensity (e.g.,
wind speed, rainfall intensity) and the associated perception on risk
on an ordinal scale range from 0 (no risk) to 10 (high risk). Survey
information was also collected  before and after the experiments. This
presentation will provide an overview of the experimental design,
review the data analysis (multi-level modeling) and discuss
preliminary findings. The authors will then coordinate a open
discussion about the implications of these findings with regard to
advisories and future research efforts that will build upon this work.
Feedback will be used in a forthcoming paper that comprehensively
addresses project components.
