clear air turbulence

How often does severe clear air turbulence occur over tropical oceans?

热带海洋晴空发生强气流涡动的频率如何?

in addition, this simplified equation was tested using the environmental technical application ( eta) mode and the data of 100 cases of clear air turbulence ( cat) in flight.

根据收集到的100例飞行中晴空颠簸的实际资料，利用环境技术应用（ETA）模式对该简化方程进行了检验。

the beginning researches and manufacture of airborne laser radar detecting clear air turbulence system is to adapt to the demand of the modern aviation development.

机载激光雷达晴空湍流探测告警系统正是适应现代航空发展的需要而开始研制的。

the second part of this paper is clear air turbulence detection theories foundation.

第二部分为晴空湍流探测理论基础。

We are getting into clear air turbulence emergency descent to 8000 m.

我们进入晴空颠簸,紧急下降到8000米.

there are many different kinds of turbulence, with the most problematic to predict and to avoid being clear air turbulence ( which is very difficult to detect using conventional radar).

乱流有很多种，其中晴空乱流最难预测与回避，常规雷达很难侦测。

based on the statistic independent property of the effects of rough surface and atmospheric turbulence on a propagation laser beam, a formulation for the probability density function of the unwrapped phase of a elliptic gaussian speckle field that propagates through clear air turbulence is developed.

根据粗糙界面和大气湍流对传输激光束影响的相互统计独立性，给出了通过洁净大气湍流传输的椭圆高斯分布散斑场的非限制相位概率密度函数。

Suddenly she was scared to death of clear air turbulence.

她突然之间被晴空乱流吓死了.

thus, it is a hotspot to detect clear air turbulence with lidar.

因而通过激光测风雷达探测晴空湍流是国际上研究的热点。
