摘要 利用NCEP1°X1°再分析资料,使用客观分析的方法,对2010年西北地区的航空器空中报告中的中度以上颠簸物理量场进行分析,发现中度以上颠簸发生区域具有水平散度梯度、水平垂直速度梯度、水平涡度梯度大的大气动力学特征,为中度以上颠簸预报提供了新的思路和依据。 Div gradient and vor gradient and ω gradient are compressed in moderate and severe turbulence area that happened in Northwest China in 2010 by analysis NCEP1° X1°FNL data through objective analysis, abovementioned discovery can help to find a new idea in moderate and severe turbulence forecast.
