演变

The results are as follows:① The mean spatial position of the tropical tropopause and the polar tropopause approximately consistent with heating fields of the tropopause, and isopiestic, isotherm present zonality and appear wave motion at the middle and high latitude . The tropopause temperature and pressure are not symmetrical between two hemispheres.② The interannual variations of the tropopause zonal-mean pressure and temperature anomalies are remarkable.

结果表明：①热带对流层顶和极地对流层顶的平均气压场的空间位置和热状况大致吻合，并存在空间波动性，两半球对流层顶的温压场具有显著的非对称性；②对流层顶的纬向气压与温度距平场都具有不同尺度的年际和年代际变化，两极地区对流层顶的温压场最不稳定，两半球中纬度地区的时间演变尺度存在明显差异。
