摘要:

土壤焓作為一種綜合考慮地表狀況（如土壤濕度、土壤溫度等）的特殊陸面因子，可以直接從能量角度反映陸地下墊面的熱力狀況，故探討土壤焓異常持續(xù)性的相關(guān)特征，有助于加深理解地表熱力異常對氣候的影響。本研究基于陸面過程模式CLM4.0模擬的土壤溫度、土壤液態(tài)水和土壤固態(tài)水及土壤物質(zhì)類型（IGBP地表屬性），分別計(jì)算了歐亞大陸冬季和夏季土壤干物質(zhì)焓、土壤液態(tài)水焓和土壤固態(tài)水焓及土壤焓（前三者之和）；由于土壤溫度和土壤固、液態(tài)水含量的差異，淺層土壤焓及其三個(gè)組元表現(xiàn)出明顯的區(qū)域性和季節(jié)性特征；歐亞大陸冬季土壤焓異常持續(xù)性總體較夏季強(qiáng)，尤其是中高緯地區(qū)；另外，土壤干物質(zhì)焓、液態(tài)水焓的緯度和季節(jié)性差異也體現(xiàn)在對近地面大氣的熱力強(qiáng)迫上，具體表現(xiàn)為土壤干物質(zhì)焓、液態(tài)水焓分別與感熱、潛熱密切相關(guān)。本研究通過較為細(xì)致地分析土壤焓異常持續(xù)性的時(shí)空變化特征，為進(jìn)一步開展下墊面熱力異常（以土壤焓表征）的氣候效應(yīng)提供了重要的信息參考。

Abstract:

As a special indicator of land surface, soil enthalpy comprehensively integrates effects of various land surface statuses (soil moisture, soil temperature, etc), and directly reflects land surface thermal conditions based on energy theory. Therefore, the ananysis on relevant features of soil enthalpy anomaly persistence is favorable for deeply understanding thermal impacts of land surface on climate. Based on the soil temperature, soil liquid water, soil ice and the IGBP (International Geosphere-Biosphere Programme) soil types across Eurasia obtained from off-line simulations of the Community Land Model (CLM4.0), the soil solid matter, soil liquid water and soil ice enthalpy (the sum was named soil enthalpy) were estimated. Climatologically, both shallow soil enthalpy and its three components obviously differed among regions and seasons, mainly due to the differences in soil temperature, and contents of soil liquid water and ice. With respect of soil enthalpy anomaly persistence over Eurasia, it was generally more robust in winter than in summer, especially for the mid-and high-latitudes. Moreover, the closer relationships of soil solid matter enthalpy with sensible heat and soil liquid water enthalpy with latent heat indicated that soil enthalpy could impact the near surface atmosphere through the pathways of therrnal heating. Importantly, the relatively comprehensive analyses on spatio-temporal characteristics of soil enthalpy anomaly persistence in this study provided critical references for conducting researches about land surface thermal anomaly induced climate effects.
