Investigation of the wind environment by Community Participation in Musashikosugi Area

(Part 2)Proposal of Wind Force Scale based on free description by local residents

Abstract

The purpose of this paper is to propose a new wind force scale based on free descriptions by local residents to examine the relation between wind speed and the impressions or phenomena caused by the wind.
Firstly, the free descriptions were categorized into 6 groups such as “tree”, “hat, hair, clothes”, “umbrella”, and so on. Next, for each group, the characteristic words in the free descriptions were extracted by Text Mining. A new wind force scale for each group was proposed based on the sentences including the extracted characteristic words.
