1) 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。
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) upwind district
逆风地区
4) upwind
[英][,ʌp'wɪnd] [美]['ʌp'wɪnd]
逆风
1.
Removing upwind/downwind ambiguity of ocean wind direction by polarimetric microwave radiometer:Algorithmic basis
一种消除全极化微波辐射计顺/逆风向遥感模糊性的新方案——算法研究(英文)
5) HW Head Wind
顶风,逆风
6) Against wind
逆风、顶风
