【摘要】：應(yīng)用南京城市氣溫觀測數(shù)據(jù)對一個2017年最新提出的日最大熱島強度診斷方程進行了檢驗,這是首次用歐洲之外的城市氣溫實測數(shù)據(jù)對該方程進行檢驗。南京氣溫觀測實驗基于城市局地氣候分區(qū)(Local Climate Zone,LCZ)方法進行,該方法是一種用于城市氣溫研究的客觀標準的局地熱氣候分類方法。用于本次研究的氣溫觀測數(shù)據(jù)來源于南京城區(qū)7個不同類型的LCZ地塊,從2016年7~11月期間挑選出29 d天氣特征為晴朗、微風、少云的典型氣象日。對比分析了各LCZ地塊的日最大熱島強度觀測值和基于該診斷方程的計算值,結(jié)果表明:該方程的整體精度(r~2=0.46,RMSE=1.08 K,MEAE=0.76 K)接近其在歐洲西北部14個城市的診斷表現(xiàn)(r~2=0.65,RMSE=0.91 K,MEAE=0.58 K),初步表明該方程可用于診斷我國城市的日最大熱島強度。
[Abstract]:A new diagnostic equation of maximum daily heat island strength proposed in 2017 is tested by using Nanjing city temperature observation data. This is the first time that the equation has been tested with the measured data of urban air temperature outside Europe. The temperature observation experiment in Nanjing is based on the urban local climate zoning (Local Climate Zone,LCZ) method, which is an objective standard local geothermal climate classification method for urban temperature research. The temperature observation data for this study come from seven different types of LCZ plots in Nanjing urban area. From July to November 2016, the typical weather days with 29 days of clear weather, breeze and less clouds were selected. The observed values of maximum daily heat island strength of each LCZ block and the calculated values based on the diagnostic equation are compared and analyzed. The results show that the global accuracy of the equation (RMSE 1.08 K / MEAEN 0.76K) is close to its diagnostic performance in 14 cities in northwestern Europe (RMSE 0.91 Ke MEAEN 0.58 K),). The results show that the equation can be used to diagnose the maximum daily heat island intensity of Chinese cities.
