Its location varies with the seasons, since the polar front moves south in winter and north in the summer.

它的位置会随季节变化，由于极锋冬季向南移动，夏季向北移动。

The results show that the structures and characteristics of the meiyu front are different for various cases, or at various places and time, or at variious stages of one case, and the frontal characteristics can be transited from the polar front to the equatorial front.

结果表明，不同的个例，不同的地区和时期，一次梅雨过程的不同阶段，梅雨锋的结构和性质都有可能不同，它可以从比较接近极锋的性质过渡到接近赤道锋的性质。

In terms of atmospheric circulation, explain the different climatic characteristics of the Inter-topical Convergence Zone and the Polar Front in the western Pacific region.

以大气环流解释西太平洋地区热带辐合带与极锋的气候特徵差异。

Convergence is stronger than divergence in the Polar Front Zone,indicating that a part of the converging water must come from the cold water transporting northward from south of PFZ and contribute to the formation and maintenance of the lateral temperature gradient of SAF.

极锋区(PFZ，指极锋PF与亚南极锋SAF之间的区域)中辐聚大于辐散，部分辐聚的水体必定来自极锋以南向北输送的温度更低的上层水，对SAF水平温度梯度的形成和维持做出贡献。

Chen et al noted that there are three kinds of landfall typhoon tracks; subtropical high and polar front, whose evolutions and adjustments may modify typhoon movement, are the main synoptic systems which influence the track of landfall typhoon.

陈联寿等根据(1949-1976)年资料，指出：登陆台风路径可分为三类；副热带高压和极锋是影响热带气旋陆地路径的主要天气系统，它们的演变和调整会影响热带气旋的移向。

The STE dominated by the intrusion of stratospheric air has been testified as a cause of ozone enhancement in upper troposphere over East Asia at the end of March 2001. This STE relates to the surface high moving southward, the upper cold eddy deepening and drifting eastward, the convergence of Subtropical Jet and Polar Front Jet associated with the cold front, the increasing temperature gradient near the jets, and the enhancing baroclinic instability.

天气诊断和动力分析表明，2001年3月底东亚地区几个臭氧探空测站探测到的对流层上层臭氧增加是以平流层空气下传为主的STE过程导致的，此过程与地面冷高压南下、高空冷涡加深东移的天气过程、以及冷锋推进引起的副热带急流和极锋急流的移动和汇合、急流附近的温度梯度加大、斜压不稳定增强等动力因素密切相关。

The locations and orientations of the Subantarctic Front, the primary Polar Front and Southern ACC Front in the ACC of the Southeast Indian Ocean can be identified more precisely by the current distribution derived from ADCP data than by hydrographic data, because these fronts are usually accompanied by strong currents, although the speed coinciding with the SACCF is less than that of the SAF and primary PF.

在东南印度洋远离海脊和海台的深海盆以及海脊和海台的走向与ACC主轴平行的海域，高涡动能主要由周期大于90天的变化产生。SAF在东南印度洋没有一致的季节变化。

Combining a new geoid model (EIGEN-GL04S) recovered from GRACE mission and the KMSS04 model, a new mean dynamic ocean topography model are estimated over the Antarctic region. The surface Antarctic Circumpolar Current field and its Polar Front and sub-Antarctic Front are derived from MDT after filtering with a wavelet denoising method.

联合基于GRACE重力卫星观测资料恢复的重力场模型(EIGEN-GL04S1)和卫星测高推求的平均海面高模型(KMSS04)来构造南极绕极流区域的平均海面动力地形，并利用小波滤波方法去掉短波及噪声信号，进而推算大、中尺度的绕极流。

Spore shells of myxosporidia are synthesized by 2-7 chitin films. There is a polar capsule at the front-end or both ends and the polar filament in capsule. The polar filament can be drawed out from the capsule hole.
