1) effective wind
起沙风时间数
1.
The results show that on the edge of the desert, the effective wind was 2 70×10 .
结果表明 :沙漠边缘地区年起沙风时间数在 2 70× 10 4 min左右 ,输沙总量为 3 80 0kg·m-1·a-1,年输沙总量与合成输沙总量的比值在 1 83~ 2 39之间变化。
2) wind initiation of particles
风沙起动
3) Dust emission by wind erosion
风蚀起沙
4) threshold wind of transporting sand
起沙风
1.
The results showed that: (1)The threshold wind of transporting sand in the study area between March to May were most frequent, with an accumulated frequency of 38%~58%.
结果表明:①研究区3~5月起沙风发生频数最高,占全年起沙风的38%~58%;平均风速和最大风速值最大,分别为6。
5) Blown sand electrification
风沙起电
1.
Blown sand electrification intensify becomes large with increase of wind velocity and weak with enlargement of sand particle size.
利用国内大型风沙物理风洞实验模拟沙尘暴电现象 ,研究风沙起电机理 ,结果表明 ,不同风速下不同沙粒会产生不同极性的电场强度和电位效应 ,风沙电随风速增大而增强 ,且随沙粒度增大而减小 。
6) Effective wind regime
起沙风况
