内容記述
Tokyo Metropolitan area consists of western diluvial upland and eastern alluvial plain. In upland area, there are many dissected valleys arborescently, and some slope-forests remain along those valleys in patches even though in central Tokyo. It is difficult to lay out a new large park within built-up area, so such slope-forests are precious plots as a natural resource of cold air production. In first presentation, results are shown from micro-climatological observations performed in and around several slope-forests. The obvious shift of wind direction appeared at the beginning of flow-down with a sharp temperature fall of 1 or 2 degrees. In slope-forest, cold air drainage occurs earlier than plane green space because of topographical effects. In second presentation, firstly we proposed a temperature measuring method using the sound virtual temperature of the sonic anemometer-thermometer as a proper air-temperature measuring method for the investigation of water mist cooling. Secondary, in order to evaluate the psychological influence of water mist evaporation, subjective experiments were conducted in the outdoor sunny place. We succeeded to reveal the detailed air temperature variation in the outdoor real setting by the new measurement technique. And some proper condition for effective outdoor application, for example air temperature level and solar radiation shielding, were also clarified.
