A SHIFT IN INVERSION TEMPERATURE POINTS IN A NON-CONVECTIVE POOL SUBJECTED TO MULTIPLE ABSORBING LAYERS,

Abstract

A survey on temperature inversions in a non-convective pool subjected to multiple absorbing layers was conducted in cross River University of Technology, Calabar. Temperature data were generated by monitoring temperature variation with height for four experimental model pools D1,D2,D3 and D0 with one, two,three and zero absorbing layers respectively(transparent glass material of thickness measuring 0.5 cm ), using high mercury in-glass thermometers.The model pools were drums of height measuring 83 cm, perforated at graduated distances inserted with thermometers, and lagged with insulating materials(styropor) of thickness measuring 2.5 cm.The multiple absorbing layers were placed at the top of the drums at interval distances of 10 cm between them.Temperature monitoring was carried out between 6 am and 6 pm for two distinct seasons(dry and wet seasons) on hourly basis, Results obtained from this study showed that a shift in inversion temperature points occurred across the length of the three non-convective pools D1 having at 45.0 cm, D2 at 35.0 cm and D3 at 21.0 cm. The range of inversion temperature was between 0.1oC to 15 oC and occurs at all times of the day with convex(negative) inversion being more prominent.

Keywords: A Shift in Temperature inversion, Thermometer, multiple absorbing Layers, non-Convective pools.
