1) upwind district
逆风地区
2) adverse wind region
逆风区
1.
Long life cycle adverse wind regions in Doppler radial velocity images were observed during the snowstorm.
结果表明:这次暴雪发生在西北气流、较大海气温差和半岛的丘陵地形特殊条件下;冷流暴雪在多普勒天气雷达径向速度图上表现为长生命史的逆风区。
2.
The sandstorm occurred in the weak echo area which was in front of the strong echo and in the adverse wind region of radial velocity.
结果表明:高空冷空气快速东移叠加到地面热低压之上形成对流不稳定,使得中尺度对流系统快速发展;T-LnP图上500~540 hPa干暖盖有利于对流层低层不稳定能量的存储和积累,干暖盖是强对流天气发生的重要征兆;沙尘暴发生前对流系统先从低层发展,然后迅速向中层发展;沙尘暴发生后中低层雷达回波减弱;中层回波开始增强,并向下发展,降水增大后,沙尘暴减弱消失;沙尘暴发生在紧邻强回波前面弱回波区域内;地面观测沙尘暴发生、发展、消亡时间与逆风区生消演变密切相关,沙尘天气发生在逆风区范围内,强沙尘暴天气发生在逆风区外层风速大值区的强辐合上升气流中。
3) Adverse wind area
逆风区
1.
Results show that the warm advection convergence, close zero velocity field and adverse wind area which appear successively during the snowstorm are the main character of Doppler velocity.
结果表明:降雪开始后相继出现的暖平流辐合、闭合零速度区和逆风区是本次暴雪天气过程多普勒速度的主要特征;持续的垂直风向切变及强辐合等风场结构为暴雪产生创造了条件;低空东南气流对多普勒速度特征的形成及暴雪的产生起了主导作用。
4) Fengcheng area
风城地区
1.
Method New well observation method is developed during well completion after inspection of Canadian UTF technology, that is temperature monitoring of FHW001 horizontal well in Fengcheng area by pre embedding temperature measuring probes in drill pipe.
方法 通过对加拿大UTF技术的考察 ,研究新的观察井测试方法 ,即管内预埋测温探头完井新工艺 ,并对风城地区FHW0 0 1水平井进行温度监测。
5) Dongfeng area
东风地区
1.
Having investigated and observed the geological condition in Benxi in the past few years,we have summarized the sinking regularity in this area in order to predict and analyze the geology disaster in Dongfeng area,Benxi.
通过对本溪市地质环境条件现状的调查及多年的观测,总结该区采空区沉陷规律,进而对东风地区地质灾害进行预测分析。
6) wind-eroded area
风蚀地区
1.
The part wind erosion may appear because of the construction of embankment in non-wind-eroded area.
非风蚀地区铁路和公路路堤的修建可能会引起路堤局部的风力侵蚀,从而造成路堤的损坏和局部地区的扬尘。
