| 抄録 | Turbulent transport of heat in urban atmospheric boundary layer was investigated through the quadrant analysis with a field observation data. Observation of a half year long was taken in a suburban area in Tokyo and made it possible to discuss seasonal variation of transport process. Heat flux above the buildings was dominated by upward ejection of warmer air in summer. On the other hand, the downward cooler sweep accounted for the flux in winter. Ejection (sweep) was correspond to the lower (higher) wind speed. An example was shown for a linkage in which the ejection above building roofs corresponds to the buoyancy-driven upflow below the roof level. |
