垂直气压梯度
垂直气压梯度-
分析了气压分离和不分离，在几种不同的层结情况下，垂直气压梯度的截断误差。
The analysis of the truncation error in the vertical pressure gradient has been made with and without the pressure separation technique for different atmospheric stratifications .

两垂直坐标下气压梯度力计算误差在低层两者相差不大，但是往高层高度坐标的气压梯度力误差要明显小于质量坐标。
PGF errors are a little difference between the two coordinates in lower levels , but PGF errors of the height coordinate are obviously smaller than those of the mass coordinate in higher levels .
