中文摘要: |
在灾害性冰雹过程的不同阶段,大气中有不同特征的重力波出现。使用重力波周期-振幅谱的动态分析方法,把冰雹过程从不同的发展阶段加以考察,发现了一些雹云发展和重力波演变特征之间的联系。它们有助于找到一种对灾害性冰雹过程作出较长时效临近预报的方法和进行深入研究的线索。 |
英文摘要: |
Atmospheric gravity waves with different characteristls occur frequently in different stages during a severe hailstorm process. Using the dynamic analysis method of the period-amplitude-time spectrum, some definite relations between the development of hailstorms and characteristics of atmospheric gravity waves are found. Results provided some leads for further studies of hailstorm dynamics and supplied available method and indicators to judge the hailfall occurring and its damage level in the operations of hail suppression. |
