Yearly average precipitation and average wind speed
of a disaster period were calculated by using average
daily precipitation and average daily highest wind speed
(Table 2). Average precipitation of a disaster period and
average daily highest wind speed were both higher than
yearly average precipitation and average highest wind
speed. During a period of heavy rain, precipitation
increased, but wind speed did not increase significantly.
Precipitation was higher in a typhoon period than in a
period of heavy rain, with 57.86 mm and 33.10 mm,
respectively. The same was true for wind speed, with
7.78 m/s and 4.85 m/s, respectively (Table 2).
