Variationas of energy and aerodynamic terms at different stations of India

Abstract

Variations and relative contributions of energy and aerodynamic terms to evaporation, from different stations of India are studied. Energy term shows higher value during first few weeks from the beginning of the year, at stations located at lower latitude, while its value retains high at stations lying on higher longitude except for Thiruvananthapuram. Aerodynamic term is found to be high at stations located at higher latitude, while except for Calcutta, its value is seen to be higher for the stations situated on higher longitude. Considerable variations in the percentage contribution of the energy and the aerodynamic terms are observed at stations situated at higher latitude. Stations situated at lower latitude show high and low value of percentage contribution of the energy and the aerodynamic terms In most of the weeks during the year. Relative shares of the energy term to evaporation are comparatively high at stations situated in higher longitude, while a higher percentage contribution of the aerodynamic term. is observed at stations located at lower longitude except for Nagpur.
