直减率 meaning in English
lapse rate
Examples
- Saturation - adiabatic lapse rate
饱和热直减率 - Autoconvective lapse rate
自动对流直减率 - As a result , in the paper , considering the altitudinal effect ( topography factor ) and the influence on the temperature lapse rate by topography and latitude and longitude and moisture transfer , the study on the daily surface air mean , max and min temperature in the reaches of yangtze rive is attempted by five models , which include the gaussian weighted model , the gaussian weighted model associated with the error - modification , the gradient plus inverse distance squared model and the modified gaussian weighted model a and b that take topography - factor into account
本文考虑海拔高度和温度直减率受地形和经、纬度及水汽等因素的影响，通过利用高斯权重法、结合逐步订正的高斯权重法、梯度距离权重反比法和加入地形影响项(地形因子)的两种改进高斯权重法的方案a 、 b ，对长江流域的地面日平均、最高和最低气温场进行了空间化插值研究。 - As far as daily surface air mean temperature , rmsie is below 0 . 5ctc . as for daily surfac e air max and min temperature , the rmsie are respectively lower than 0 . 74 and 0 . 58 . ( 4 ) the model a takes into account the fact that temperature lapse rate changes according to such factors as topography , latitude , longitude and moisture transfer , etc . the effect of spatial interpolation that uses it is not noticeably ameliorated by contrast with using the model a . there remains a need for further study
其中，改进方案a与其它方法相比，效果较好，其me均在0 . 03以下，对于地面日平均气温场， rmsie均在0 . 50以下，对于表面大气日最高温度场， rmsie均在0 . 74以下，对于地面日最低气温场， rmsie均在0 . 58以下；在方案a的基础上，考虑温度直减率随经、纬度和地形以及水汽输送等因素变化的分区插值方案，与方案a比较，插值效果没有明显改善，因此还需要进一步的研究。
