The auxiliary shaft topsoil adopted ordinary construction and drainages in hygrometric well.

屯留煤矿副井井筒表土段采用普通法施工,利用井外降井疏干降。

The terrain affect Spatial Distribution of Precipitation by way of macroeconomics topographer and parcel height above sea level.

地形对降空间分布影响主要是通过宏观地形因素和局地海拔高度不同而起作用。

Using Doppler radar data, an algorithm for precipitation nowcast is set up by applying an improved cross-correlation extrapolation method (COTREC).

摘要利用多普勒雷达资料，采用一种改进后叉相关法(COTREC)建立了一种降临近预报方法。

The wavy distribution curve of precipitation formed on the longitudinal-arranged underlying rangegorge landforms.At leeside of range, dry valley formed due to fohn effect.

纵向排列岭谷地形，形成明显降起伏分布曲线，气流越过山岭后下沉气流带来“焚风”效应，形成干热河谷。

It is found that dry intrusion maintained during the precipitation periods.The intensity of precipitation increased with the increasing dry intrusion, which pushed the rainy region southeastwards.
