Changes of Pan Evaporation and Its Influence Factors in China
Evaporation is an important component both in surface energy balance and terrestrial water cycle, and it is also a key factor determining weather and climate conditions. It plays a significant role in the studies of water and energy balance within a certain area and estimations of water resources. I...

| description | Evaporation is an important component both in surface energy balance and terrestrial water cycle, and it is also a key factor determining weather and climate conditions. It plays a significant role in the studies of water and energy balance within a certain area and estimations of water resources. In this study, based on pan evaporation data and their variation trends from 499 stations in China, the correlations between evaporation and various influence factors, including the amount of precipitation, temperature, wind speed, sunshine duration and relative humidity, were studied in depth by means of correlation analysis and set pair analysis methods. In most regions of China, temperature change presented a contrary trend compared with the variation of evaporation, as described in evaporation paradox. However, the correlation between them was not very striking, which implied that the variation of water surface evaporation was slightly affected by temperature. |
