Study of average heat fluxes in various layers of the soil and their seasonal variation in Jodhpur

Untersuchung des Wärmeflusses in verschiedenen Schichten des Bodens und seiner jahreszeitlichen Änderung in Jodhpur


Weekly mean soil heat fluxes were worked out for 1965 and 1966 in respect of sandy to loamy sand soil of Jodhpur, India. On the average mean soil heat flux of +25 cal/sqcm/week occurs during 1st to 22nd standard week (January to May). From 26th week, which is the normal time of on-set of south west monsoon over Jodhpur to 37th week which is the normal period of its withdrawal there are large oscillations in the soil heat flux values. For instance values varied from +84 to −116 cal/sqcm/week during 1966. The weeks of rainfall have large negative fluxes while intervening dry periods have large positive fluxes. These may be partly due to transfer of heat with mass movement of water. The period from 37th week to end of the year is one of continuous decrease of heat storage with least fluctuations.


Es werden Wochenmittelwerte des Wärmeflusses in sandigem bis lehmigem Sandboden in Jodhpur in Indien für die Jahre 1965 und 1966 berechnet. Im Durchschnitt ergibt sich für die ersten 22 Wochen von Januar bis Mai ein Wärmefluß von +25 cal/cm2 pro Woche. Von der 26. Woche, in der gewöhnlich der Südwest-Monsun in Jodhpur einsetzt, bis zur 37. Woche, auf die normalerweise das Ende des Monsuns fällt, treten große Schwankungen des Wärmeflusses im Boden auf. Die Werte variierten z. B. 1966 von +84 bis −116 cal/cm2 pro Woche. In Wochen mit Regenfällen weist der Wärmefluß große negative Werte, in dazwischenliegenden Trockenperioden aber große positive Werte auf. Dies mag zum Teil auf den Wärmetransport durch die Wasserbewegung zurückzuführen sein. In der Periode von der 37. Woche bis zum Jahresende nimmt die Wärmespeicherung mit nur sehr geringen Schwankungen kontinuierlich ab.
