纬圈

X and y are Cartesian coordinates representing the zonal and meridional directions, and u and v are the corresponding velocity components.

x 和 y 分别表示笛卡儿坐标系中的纬圈和经圈方向，而 u 和 v 分别是这两个方向上的速度分量。

The scale analysis on planetary scale motion in the tropical atmosphere shows that the equilibrium between the pressure gradient force and Coriolis force in the meridional direction is easily established, which is known as the zonally semi-geostrophic motion The semi-geostrophic adaptation process in which the inertial gravity waves play an important part is relatively quick The evolution process after the semi-geostrophic adaptation process is slow and controlled by the Kelvin waves and long Rossby waves

对热带大气行星尺度运动所做的尺度分析和物理分析表明：热带大气的行星尺度运动在y方向容易实现气压梯度力与Coriolis力的平衡，它称为纬圈的半地转运动。半地转平衡的建立过程，也就是半地转适应过程相对是很短暂的，它不需要考虑f=β0y随y的变化，因而主要依靠惯性重力波为频散；而半地转平衡建立后的演变过程相对是很缓慢的，它主要受Kelvin波和Rossby波控制。

从候平均温度纬圈偏差的时间演变来看，中南半岛地区纬圈温度偏差由正转负的时间早于印度半岛地区，并分别与南海夏季风和印度夏季风爆发的时间基本对应。

Based on the review of the description of subtropical high and the research on its formation, fluctuation characteristics and physical mechanisms, it is found that the subtropical high is refered to the area where pressure is relatively larger. Its formation is due to the existence of mean meridional circulation that accumulates air mass to subtropical areas. The subtropical high is belt-like with meridionally non-uniform feature and this is a zonal mean point of view.

通过对副高的描述、形成及演变特征和物理机理的研究进行回顾，认为：副高是相对的气压的高值，是由于平均经圈环流的存在，使得有空气质量在副热带地区的堆积而形成的，成为带状，表现出在经度方向的不均匀，这是一种纬向平均的观点；同时，在这个平均的高压带上常常有闭合的单体存在，表现出纬向的不均匀。

Based on analyses of observations from the short-spaced GPS receiver array at Wuhan, the storm-time ionospheric irregularities which resulted in scintillations and rapid TEC fluctuations showed westward drifts between 21∶30 and 03∶00 LT with drift velocities changing from ~40 to ~130 m/s. And based on analyses of observations from the ultra-short spaced GPS receiver chain at Guilin, ionospheric irregularities which resulted in the L-band radio wave scintillations, showed eastward drifts around local midnight ranging from ~70 to ~55 m/s on the quiet-day and westward drifts ranging from ~150 to ~50 m/s before the midnight and eastward drifts after the midnight ranging from ~25 to ~65 m/s on the disturbed day.
