旬平均 meaning in English
mean of dekad
Examples
- The maximum of instantaneous global radiation is beyond 1000w / m2 and the ten - days average intensity is 338 . 90w / m2 because of high atmospheric transparency over semi - arid rainfed agriculture region of loess plateau between june and august . global radiation , reflected global radiation and surface long wave radiation emerge the characteristic of daily variations on a typical clear day and cloudy day , whereas atmospheric long wave radiation has not this characteristic . meanwhile , net radiation , latent heat flux sensible heat flux and soil heat flux appear the same characteristic as the mean daily variations above spring wheat field and bare soil on a typical clear day and cloudy day
黄土高原半干旱雨养农业区夏秋季大气透明度较高,晴天地面的总辐射值最大瞬时值均超过1000w m ~ 2 , 6 8月总辐射旬平均强度为338 . 90w m ~ 2 ;典型晴天和阴天总辐射、反射辐射、地表长波辐射均表现出明显的日变化特征,而雨天没有明显的日循环规律;无论是晴天、阴天还是雨天,大气长波辐射基本没有明显的日变化规律。 - With reof analyze technique , the mainly anomalous spatial features of soil humidity in the 0 - 50cm layer of huai river basin and their relations to different periods of precipitation and air temperature are specially analyzed by using the observed data including dekad averaged soil moisture , precipitation and air temperature data over the east of china from 1990 to 2000 . the results indicate that in the springtime the 30cm layer soil can be treated as a boundary
本文首先利用中国东部1990 - 2000年旬平均土壤湿度、降水和气温观测资料,通过对0 - 50cm层次土壤湿度进行旋转主分量分析( reof ) ,重点分析了淮河流域土壤湿度的时空分布特征,并初步研究了与前期、同期和后期不同时段降水与气温的关系。
