Preliminary Analysis on Temperature Fields of Jinta Oasis under Clear Sky in Summer
夏季晴空金塔绿洲温度场的初步分析

Characteristics of the temperature fields observed in the JTEX" field test were analyzed.The results are showed as follows: The cold center and the warm center of oasis formed respectively in daytime and nighttime;The interaction between oasis and desert has relation with their edge and shape;There were obvious difference of ground temperature among the observation stations due to their different sites and soil types.Generally,the ground temperature of oasis was always lower than that of desert in daytime.In oasis,the vertical variation of soil temperature could be active till 20 cm below the surface,and there was no daily variation below 40 cm;The soil temperature of different layers were same twice in one day,the deeper the layer the later the same temperature appeared.For the same two layers,the temperature-being-same in oasis appeared earlier than that in desert.The soil temperature of every layer in desert was always higher than that in oasis,and the daily variation of different layers in desert was more obvious than that in oasis.
