偏差风

诊断结果表明：偏差风场的第一模态直接与东亚夏季风环流有关，可称为季风模态；第二模态则与PJ波列关系密切，可称为PJ模态；

The results indicate that the first mode of departure wind field called monsoon mode relates directly with summer monsoon circulation of East Asia and it exists close relationship between PJ wave train and the second mode which can be called PJ mode .

根据非平静大气下弹箭运动方程组，针对航弹在风影响作用下产生的落点散布，采用脉冲修正方式对航弹落点偏差进行风校正。

According to the motion equation in the non-quietude atmosphere , the authors calculate the dispersions of bomb on the effect of the wind have adopt and the pattern of the impulse correction .

从线性化模型出发建立多输入-多输出滑模控制器，并将模型偏差、风载荷视为系统的外部扰动，通过引入参数自适应律在线估计总的外部扰动，并加以补偿。

The MIMO control law is derived with the linear model of the system . In addition , the model error and wind force are considered as the external disturbances , which are estimated on line and compensated .

结果表明，在土壤湿度空间分布不均匀的情况下，运用Mosaic方法计算得到的地表潜热通量偏小，背景风较小的时候偏差较大，背景风增强时偏差减小。

The results show that , under the sub-grid heterogeneous distribution of soil moisture , the surface latent heat flux calculated by Mosaic method is smaller than their true values . Moreover , with the background wind increasing , the deviation decreases .
