三旬三旬
  1. 炎暑惟兹夏,三旬将欲移。

    This sweltering heat will take its leave of us , the summer months will not want to stay .

  2. 预报结果表明,三种方法的旬和月平均预报均超过惯性预报的水平,其中以后两种方法为佳。

    The forecasts of 10-day and 30-day average by using three methods mentioned above , especially the last two , have an improvement over a persistence forecast .
