Applying Dalton’s law of potential evaporation rate over the territory of Russia and neighboring countries using long-term observation data

Parameters of the relationship between wind speed W and conductance G , used in Dalton’s law for potential evaporation rate, were estimated from the long-term field monitoring data on potential evaporation at 81 stations of the State Hydrological Institute. Linear dependence on W was assumed, that i...

Summary:Parameters of the relationship between wind speed W and conductance G , used in Dalton’s law for potential evaporation rate, were estimated from the long-term field monitoring data on potential evaporation at 81 stations of the State Hydrological Institute. Linear dependence on W was assumed, that is, G ( W ) = g 1 + g 2 W . The estimation yielded g 1 = 165.2 and g 2 = 99.9. These parameters were employed for computation of potential evaporation rate from routine meteorological data for locations of 2460 meteorological stations of the former USSR territory. The computed estimates were then compared with some published calculated values and with the data of direct potential evaporation rate measurements at 254 geographical points. The comparison yielded satisfactory results.
