水廓 meaning in English

water region

Besides , the information on actual height of lowest cloud base is used in constructing of cloud liquid water profile by using radiosonde profiles , that makes an improvement of relative accuracy of retrieved value of l at almost all altitudes by 5 - 20 % according to numerical simulation comparison . the lower the altitude is , the more the accuracy is improved
为减少由于回归样本中云液水廓线的‘失真’给反演造成的误差，本文在对探空廓线作诊断建立云液水廓线时，引入了实际目测的最低云底高的信息。数值模拟比较表明该措施行之有效，使对流层中下层的几乎所有高度上l反演值的精度提高5 - 20 ，观测高度越低，精度提高越多。
