摘要

摘要: 利用NCEP/NCAR再分析月平均资料，研究了1979—2002年夏季全球对流层顶气压和气温的分布特征与变化趋势。选取了夏季北半球对流层顶年（代）际变率最大区域来定义气压指数和气温指数。分析结果表明：（1）全球对流层顶气压和气温在北半球随纬度的增加而增大，在南半球随纬度先增大再减小，而在整个热带地区对流层顶气压和气温的分布则较为均匀。（2）全球平均的对流层顶气压和气温在分析时段内呈减小趋势，但在中高纬度地区对流层顶气压和气温存在大范围增大现象，表明二者的趋势并不是全球一致的。（3）对流层顶年（代）际变率最大值出现在北半球的中纬度地区和南半球的副热带及高纬度地区，最小值则出现在热带地区。气压指数和气温指数显示出准10年和准3～5年周期。
