摘要

摘要: 本文选取1981年7月至2012年12月美国国家航空和航天局（NASA）制作的归一化的动态植被指数（NDVI）资料、根据NDVI值计算地表热力输送系数（C_H）的参数化关系式（C_H-I_NDV）和青藏高原70个常规气象观测资料，计算了青藏高原全区的逐月地表热力输送系数（C_H），讨论了其时空分布特征，并在此基础上计算了高原70个常规台站的感热通量（SSHF）序列，并与已有感热资料进行了对比。随后，探讨了地面感热通量的气候特征及其年际变化与气候因子的关系。结果表明：高原地区的C_H值具有明显的空间差异和季节差异，表现为东高西低、夏季大、冬季小的特点。感热的年际变化在冬季主要响应于地气温差的变化，夏季则受地面风速影响较大；由于风速减小趋缓，地气温差增大，变化趋势在2003年前后由减弱趋势转变为增强趋势，这种趋势的转变最早发生在2001年秋季，且在高原全区具有较好的一致性。

Abstract: Based on normalized difference vegetation index(NDVI) data for the period of July 1981 to December 2012 from National Aeronautics and Space Administration(NASA) and observations collected at 70 meteorological stations in the Tibetan Plateau,, the C_H-I_NDV parametric relational expressions which giving the relationship between NDVI and surface heat transfer coefficient (C_H) are used to calculate monthly mean surface heat transfer coefficient (C_H) over the entire plateau. Characteristics of spatial distribution and temporal variability of the C_H are discussed, and monthly mean surface sensible heat fluxes (SSHF) at the 70 meteorological stations have been calculated using a bulk transfer method. Results are compared with available observations. Climatic features of SSHF and the relationship between SSHF and climatic factors are then analyzed. Results show that the C_H value has significant spatial and seasonal differences with high values in eastern Plateau and in the summer and low values in western Plateau and in the winter. The interannual variation of SSHF is mainly affected by changes in surface wind (v) in the summer, while in the winter it is largely affected by changes in the difference between surface temperature and air temperature (T_s-T_a). Since the decreasing trend of v slowed down in 2003 while T_s-T_a increased at the same time, interannual changes in SSHF switched from decreasing to increasing at around 2003. Note that such a switch first occurred in the autumn of 2001 over the entire plateau.
