场的散度 meaning in Chinese

divergence of field

Tests are conducted to determine the sensitivity of the simulation to the available pbl parameterization schemes , including the hir scheme , bt scheme , eta scheme , mrf scheme and gs scheme . significant sensitivity is seen that the structure of meteorological fields and the precipitation vary greatly with different pbl schemes
结果表明：在不同的边界层参数化方案下，垂直速度场、水汽通量散度场、涡度场、水平风场的散度以及_ ( se )场都表现出不同的特征；合理边界层方案的引入对预报效果有明显的改进。
