| 中文摘要 | 为了研究蒸发互补关系的区域变异性,该文引入了水汽压-温度(p-t)状态空间。在蒸发互补关系中,湿润环境蒸散发量通常采用Priestley-Taylor(P-T)公式进行计算。研究表明:大气环流和洋流将热量和水汽由低纬度向高纬度输送,导致P-T公式中的参数α随纬度增高而增大;海陆之间的大气运动将水汽由海洋输送到陆地,导致α随着离海洋距离的增加而减小。这与中国108个流域的水文气象数据所揭示的规律是一致的。; To describe the regional variability of the complementary relationship between the actual and potential evapotranspiration,a pressure-temperature(p-t) state space was defined.In this complementary relationship,the wet environment evapotranspiration(Ew) is usually calculated from the Priestley-Taylor(P-T) equation.This analysis shows theoretically the parameter α increases with latitude as a result of the annual transport of the energy and vapor from low latitudes to high latitudes through the atmospheric and oceanic flows.Atmospheric circulation between continent and ocean transports vapor from the oceans to the land,so α decreases with distance from ocean.This conclusion is consistent with numerical analysis using water balance data from 108 catchments of China. |
