摘要
基于ERA-Interim再分析逐日温度资料,依据温度递减率插值法,计算出两类对流层顶(热带对流层顶和极地对流层顶)的频率数据。分析了高原与同纬度地区两类对流层顶频率的季节变化特征及其差异,并初步讨论了高原两类对流层顶频率与其上空各层温度的关系。结果表明:1)高原在5-10月热带(极地)对流层顶频率增加(减少),11月至翌年4月热带(极地)对流层顶率减少(增加);其中极地对流层顶频率季节变化尤为明显,夏季很少出现,此时高原以热带对流层顶为主,其他季节则以复合对流层顶为主。2)北半球,热带(极地)对流层顶频率大致成带状由南向北递减(增)。与同纬度地区相比,高原在暖(冷)季热带对流层顶频率较同纬度地区偏多(少);与此相对应,暖(冷)季高原对流层中上部(平流层下部)各层温度较同纬度地区明显偏高(低)。3)高原高空各层温度与两类对流层顶频率具有紧密联系:对流层顶中上部温度与热带(极地)对流层顶频率存在显著的正(反)相关关系,而平流层下部温度与热带(极地)对流层顶频率为明显的反(正)相关关系。
