Abstract

The paper summarises the results of wind, temperature and evapotranspiration observations taken over a wheat field at Poona. Daytime variations of zero-plane displacement, temperature and wind speed are presented. Their systematic variation during the day is also expressed mathematically. Comparison of evapotranspiration by Thornthwaite's original formula as modified by Rider and lysimetric values has been made. Better agreement could be obtained between lysimeter values and computed evapotranspiration both averaged over a ten-day period by abandoning the assumption of logarithmic variation of vapour pressure in Thornthwaite's formula and by employing the diurnal variation of zero-plane displacement.
