摘要
作者考虑到雨水耗热,得到如下计算日蒸发量的公式E=[ΔR_(n)+0.5E_(a)(1+I_(d)/190)]/[Δ+0.5(1+I_(d)/190)],式中I_(d)是日降雨量(毫米)。在降雨大的情况下,用此式计算的结果看来比Penman公式要好。
The wasting heat of rainwater is considered,we have obtained following formula for estimating the diurnal evaporation E=[ΔR_(n)+0.5E_(a)(1+I_(d)/190)]/[Δ+0.5(1+I_(d)/190)] where I_(d) is the daily rainfall(mm).The calculations show that this formula is more accurate than the Penmen’s formula when the rain fall is heavy.
