纬度

In the thesis, it was shown that the latitude variation of the angular dispersion should mainly depend on square sum of lower degree deduced Gaussian coefficients if the non-axial-dipole component vs. the axial-dipole component is small.

本文证明，如果地磁场非轴向偶极子分量相对轴向偶极子分量为小量，那么VGP角散布的纬度变化主要由低阶约化Gauss系数的平方和决定。

Astronomy The angular distance of a celestial object above the horizon.

地平纬度：地平线以上天体的角度距离 4。

At mid-northern latitudes, Antares sets shortly after nightfall at this time of year.

在中北纬度每年这个时候，心大星在日暮后很快就落下了，在更北方会落得更快。

The approximate structure of nonlinear action of climatic atmosphere and ocean is: the nonlinear action decreases usually with increasing latitude, which is related to the role of the Coriolis force in fluid motion; the nonlinear action changes with the anomalous cyclonic or anticyclonic circulation shear, for instance, when the strength of anomalous eastward zonal circulation is comparable to that of anomalous meridional circulation, the nonlinear action is the strongest; wind stress plus gradient forces enhance the nonlinear action, etc..

气候海洋与大气非线性作用的大致结构是：通常与科里奥利力对流体运动的规范作用有关，非线性作用随纬度增加而减弱。距平流场的切变结构及其沿经向与纬向上强度的比较直接改变气候大气和海洋的非线性作用(比如，向东的距平环流强度与经向环流强度相当时，非线性作用最强)，较强的外部驱动使非线性作用加大等等。

This was also the year they introduced the prototype FCT-150 fluorite triplet apochromat and the revolutionary EM-2000 mount which used electric clutches and had a direct read out of R.A. and Dec.

这一年也是FCT-150萤石三片式APO折射镜和革命性的EM-2000型赤道仪问世的时间，EM-2000使用电子装置可以直接读出赤经/赤纬度。

Mariners were also able to fix their latitude , by using an instrument called an astrolabe

海员们还可使用星盘这种仪器确定纬度。

The model is based on two extended heat sources, one is on day side of the auroral oval and the other on night side.

夏季负相扰动发展到较低的纬度，冬季在中纬正相扰动是主要的。

It will also have a low-latitude magnetic effect, but because of distance, effect is much weaker than the auroral zone.

它在中低纬度也会产生磁效应，只不过由于距离较远，效应较之极光带弱得多。

This nice boardinghouse is situated in the small village of Grabovac, 8 km away from the Plitvice Lakes National Park, a UNESCO world heritage site.

Plitvice的湖位于Lika的山区，16个湖位于不同的纬度，被石灰华栅栏分隔着，并由瀑布和人工瀑布相连。

Boreal forest becomes one of the zones most significantly influenced by global climate change.

北方针叶林地处北半球中高纬度地区，增温剧烈，是受气候变化影响最显著的地区之一。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.
