摘要：

The continuous measurement of night-time ET(a,n) (sunset to sunrise), daytime ET(a,d) (sunrise to sunset) and 24 h ET(a,24 h) alfalfa evapotranspiration was carried out, using the Bowen ratio-energy balance method, in a closed mountainous semi-arid irrigated valley in northern Utah. The results indicate that ET(a,n)/ET(a,24 h) was 2.93 mm/173.87 mm, or about 1.7%, during a complete growing cycle of alfalfa in August and September 1991. The results also show that this ratio could be very high (about 14%) when the night-time wind speed is high.
