High-resolution boundary layer radar (BLR) and wavelet are utilized to observe microscale downdraft-updraft combinations. High-resolution BLR can observe thermal activity that pushed the stable layer. During this thermal, a combination of downdraft-updraft was also observed. A detailed observation of this combination was conducted in this study. Using a 1-dimensional continuous wavelet transform with Paul wavelet, we could quantify this downdraft-updraft combination based on the height and period. Using this quantification and wavelet variance in different weather conditions, we showed the essential period from 0 to 0.25 min, 2 to 4 min, and 4 to 8 min of this microscale downdraft-updraft combination.

高分辨率边界层雷达（BLR）和小波被用来观察微尺度的向下-向上-向上组合。高分辨率BLR可以观察到推动稳定层的热活动。在该加热过程中，还观察到了向下气流-向上气流的组合。在这项研究中对此组合进行了详细的观察。使用带有Paul小波的一维连续小波变换，我们可以根据高度和周期来量化这种向下-向上组合。使用这种量化和小波方差在不同的天气条件下，我们显示了这种微尺度向下-向上-向上组合的基本周期为0到0.25分钟，2到4分钟以及4到8分钟。
