This, in turn, is equal to the highest value of the stall speed (VS0) multiplied by 1.3 or stall speed at 1G (Vs1g) multiplied by 1.23 of an aircraft in a normal landing configuration at its maximum certified landing mass.

https://www.weather.gov/source/zhu/ZHU_Training_Page/clouds/cloud_development/clouds.htm Formation of cloud requires a continuation of the lifting process. It is assisted by the property of water of giving off heat when changing from vapor to liquid and solid states, the latent heats of condensation and of deposition, respectively. (If the vapor first changes to a liquid before freezing, then we also have
Disk brake (Disc brake)
Modern general aircarft (GA) and airliner are also use disc brake Types of disk brake (disc brake) Singel disc Multi-disc Composition of disc?

Types of meteors (WMO)
Ref : https://cloudatlas.wmo.int/en/general-classification-of-meteors.html (4) Four types of meteors (WMO): 水 moisture related 光 light related 電 electrical related 塵 dust and particle related Meteors present a great diversity of character. However, by considering their constituent particles or the physical processes surrounding their occurrence, meteors can be classified into four groups: hydrometeors, lithometeors, photometeors and electrometeors. 大氣現象呈現出多種多樣的特徵。但是，根據它們的組成粒子或它們發生期間的物理過程，大氣現象可以分為四組：水凝物、大氣塵粒現象、大氣光學現象 和 大氣電學現象。
