| 英文摘要 | Pan measurement is a reliable and efficient method for indicating the evaporative demand of the atmosphere. There are several types of pan evaporimeters worldwide, and the estimation of the conversion coefficients (K-p) between them is necessary in hydrologic research. In China, E601B pans were installed at all meteorological stations beginning in 1998. They replaced the 20 cm pans (phi 20). To fully use the records from the two pans and obtain long-term pan evaporation, the spatial patterns of K-p between phi 20 and E601B and the factors that influence K-p are investigated based on records from 573 national meteorological stations from 1998 to 2001. In this study, The results show that higher K-p values are found in southwestern regions and lower values are found in northeastern regions during the warm seasons (from May to September), while K-p values are lower during warm seasons than during cold seasons (from October to April the following year). In addition, net radiation was found to be the dominant climate factor that affects variations in K-p, followed by relative humidity and the vapor pressure deficit. This study can improve the benefit of not only the selection of appropriate evaporimeters by meteorological departments, but also of the study of temporal variability and trends in the evaporative demand. |
