upward air current meaning in Chinese
上升气流
Examples
- Before flying , glider and sailplane pilots may be interested to know if there is adequate lift due to upward air currents
在飞行之前，滑翔机师及模型机操作专家可能想知道有没有上升气流提供足够的抬升动力。 - Before flying , glider and sailplane pilots may be interested to know if there is adequate lift due to upward air currents
在飞行之前，滑翔机师及模型机操作专家可能想知道有没有上升气流提供足够的抬升动力。 - This webpage provides two weather indices , namely the " thermal index " and the " soaring index " , to let the glider pilots estimate whether there is adequate lift due to upward air currents for soaring activities
该网页提供了两个天气指数：热成指数和滑翔指数，以协助滑翔飞行员评估是否有足够的上升气流进行滑翔飞行活动。 - Regional photochemical reaction is weak over this area , to a great extent , the atmospheric background condition influences to the variation of surface o3 , tthe variation of vertical wind speed is significant to surface o3 , from seasonal distribution of vertical wind , it appears upward air current in winter , spring and autumn , repectively , while it is mainly downward in summer , it is favorable to the o3 transport from stratosphere layer . at walilguan , the variation of humidity impacts a little on surface o3 , the relationship between surface o3 and wind speed is relatively complicated , by correlation statistic analyze , it is sure that the wind speed is not one of the important factor
( 2 )瓦里关地区局地光化学反应较弱，地面o _ 3在很大程度上受大气背景状况的影响； ( 3 )垂直风变化对地面o3日变化影响较大，从垂直风季节分布看，春、秋、冬三个季节为上升气流，而夏季下沉气流则很旺盛，这种分布有利于平流层o _ 3向下的输送； ( 5 )湿度对地面o _ 3贡献并不明显； ( 6 )各季节水平风速与地面o _ 3之间的关系较为复杂，不同季节相关分析表明，水平风速并不是影响地面o _ 3变化的主要因子之一。
