研究了1948 ~ 2007年60年期间地中海地区大气静态稳定性的季节特征以及1948 ~ 1962年、1963 ~ 1977年、1978 ~ 1992年和1993 ~ 2007年4个15年子周期。采用s型因子分析和t型因子分析对地中海地区K静态稳定指数的5天平均值进行分析。k指数年际变化和空间分布均有三种主导模式。研究发现，这些模态与影响该地区的主要大气环流系统的季节特征和地球表面（陆地或海洋）的热特性有关。四个子期结果的差异部分反映了上述因子强度的年代际变化。
The seasonal characteristics of atmospheric static stability in the Mediterranean region are examined, for the 60-year period 1948–2007 and for the four 15-year sub-periods 1948–1962, 1963–1977, 1978–1992 and 1993–2007. S-Mode and T-Mode Factor Analysis are applied to the mean 5-day values of K static stability index over the Mediterranean region. Three dominant modes are revealed for both, the intra-annual variation and the spatial distribution of K-index. It is found that these modes are connected to the seasonal characteristics of the main atmospheric circulation systems affecting the region and the thermal properties of the Earth’s surface (land or sea). The differences among the results of the four sub-periods partially reflect the inter-decadal variations of the strength of the above factors.
