纬向指数 [wěi xiàng zhǐ shù]
zonal index
- 特别地，亚洲极涡、纬向环流指数、西太平洋副热带高压北界位置及太平洋暖池的海表面温度等因子均通过了95%（90%）信度水平检验。
Especially, t-test shows that significance of the Asia polar vortex, zonal circulation index, the most northern extension edge of subtropical high of Northern West Pacific and the warm pool of Pacific Ocean, are at 95%（90%）. - 通过上述对蝗虫发生有明显影响的大气环流特征值进行回归分析，结果表明，上年9月和当年4月大西洋副高脊线、3月大西洋副高北界、上年9月西藏高原指数、5月亚洲区极涡面积和3月亚洲纬向环流指数与发生面积拟合较好，说明这些大气环流特征值的强弱是决定东亚飞蝗发生的关键因素。
The conclusion drawn from the regression analysis of character indexes of the atmospheric circulation mentioned above shows that the area attacked by locusts can be preferably simulated by these key factors below: the Atlantic subtropical high's ridge line in Sep. of the last year and Apr. of the same year and that of the north demarcation line in Mar. of the same year, the Tibet plateau from Sep. to Oct. of the last year, the polar whorl area in May and the latitudinal atmospheric circulation in March of the same year in Asia.
