日较差 meaning in English
daily amplitude
daily range
diurnal range
variation of the rate
Examples
- Difference between the daily maximum and minimum readings
日较差每日录得最高和最低值的差距。 - The capacity of the decrease of maximum air temperature in forests was the principal factor of decreasing the annual mean differences in daily range of temperature
这4种森林的年平均日较差依次为5 . 9 、 4 . 6 ， 3 . 6和3 . 1 ，且月变异系数逐渐减小，森林主要通过降低日最高温而减少林型间气温日较差。 - The daily variation of surface o3 is different under different weather condition , the variation of surface o3 in spring , autumn and summer is almost same when it is clear . in spring and autumn , under the condition of clear sky , its value is higher than that in cloudy or rainy / snowy day , while its variation is not obvious in winter and summer ; in rainy and snowy season , the variation of surface o3 in spring , autumn and winter is insignificant , bnt in summer , it is significantly different from other seasons , daily difference is the highest among all seasons , it has some important relationship with rain / snow , moreover , the function of rain and snow to the varation of surface o3 is different
( 2 )不同天气条件下，春、夏、秋、冬四个季节地面o _ 3浓度变化不尽相同，晴天和多云天，春、夏、秋季的地面o _ 3变化趋势基本一致，其中，春秋季，晴天o _ 3值高于多云天和降雨天，而冬季和夏季则不明显；各季节降雨、雪天o _ 3浓度的变化情况来看，地面o _ 3在春、秋、冬三个季节变化不大，而夏季与其它季节明显不同，变化幅度很大，日较差在四个季节中为最大，这与降雨、降雪关系很大，并且可能存在雨、雪的差异。 - The results show that the local average temperature and average surface temperature will rise , and both daily difference will rise , too . average sensible heat flux and its daily difference will also increase while average latent heat flux and its daily difference will reduce after the vegetation degration of some area in the west of liaoning province ; the average temperature will raise 0 - 0 . 5 , average surface temperature will raise 0 - 1 . 0 , average sensible heat flux will increase 5 - 40w / m2 , about 8 - 55 % and average latent heat flux will reduce 5 - 60w / m2 , about 4 - 48 %
模拟结果表明：在辽西部分地区植被退化后，当地6 、 7 、 8三个月的夏季平均气温和平均地面温度升高，两者的日较差增大，平均感热通量及其日较差也增大，平均潜热通量及其日较差减小；平均气温升高0 0 . 5 ，平均地面温度升高0 1 . 0 ，平均感热通量增大5 40w / m ~ 2 ，约8 55 ，平均潜热通量减小5 60w / m ~ 2 ，约4 48 。 - Regional difference in lower - level temperature dv and pressure dv are greatly weakened and dv of llj is distinctly faint without the nanling ridge . this result show that nanling ridge acts as a critical role in the establishment of dv of the lower - level temperature and pressure , which give rise to the dv of llj in south china
而当模式中仅仅去掉南岭和武夷山山脉地形后，低层大气温度场日变化的区域性差异明显变弱，梅雨低压带南侧原南岭山脉所在地的温度日较差明显减小，使得梅雨低压槽与华南地区之间的南北向水平温度梯度和水平气压梯度的日较差显著变小，导致华南低空急流日变化的显著减弱。
