    Abstract

    The clo index, a measure of comfort providing an indication of clothing requirements under a given set of atmospheric conditions, was employed to assess the winter human bioclimate in Hong Kong. Hourly clo values for 8 stations were computed using hourly air temperature, wind speed and cloud cover data from 1991 to 2000, and they were reduced and grouped into monthly and seasonal values. A zonal pattern of clo requirements was observed. It was discovered that the hilly terrain blocked the cool northerly air making the southern part of the territory having the lowest clo values. Comfortable and cool weather wears comprised about 50-60 percent of the time at various stations. A statistically significant decreasing trend of clo values was detected at the Hong Kong Observatory; and this was mainly associated with the effect of urbanization.
