几种海面放热量体积法估算式的比较

A COMPARISON OF SOME ESTIMATING FORMULAS OF THE AERODYNAMIC BULK METHOD

本文依据日本气象厅东海浮标资料(1987年1月),用Jacobs,Deacon,Kondo等体积法估算式作海面放热量(潜热与感热之和)估算。估算结果揭示了不同估算式所具的量值上的关系。Kondo式估算结果与Jacobs式估算结果在中性条件下约为0.6,在非绝热条件下约为0.7;Deacon式估算结果与Jacobs式估算结果之间也有一定的转换关系。这些结果有可能为用不同估算式所作的海面放热量估算的文献进行量值比较。

Based on the data collected with buoy in the East China Sea and published by Japan Meteorological Agency (January,1987), the surface heat fluxes (sum of latent heat flux and sensible heat flux) are estimated by means of the various aerodynamic bulk formulas given by Jacobs, Deacon and Kondo. The results obtained from the estimations revealed some relationships among the different formulas. The result shown by Kondo's formula vs that by Jacobs is about 0.6 under neutral condition, and about 0.7 under diabatic condition. There also exist some relationships of conversion between the formulas of Deacon and Jacobs. These results may offer a possibility to compare the estimations of surface heat fluxes by different methods as reported in the concerned papers.
