Effects of Wind Speed on Shape and Fall Velocity of Raindrops
In order to study the effects of different wind speeds on the shape and speed of raindrops, other factors were first ignored to discuss the effects of different wind speeds on the shape of the raindrops. Through the Beard and Chuang models, it is found that the raindrops deform when the raindrop diameter is larger than 1mm, and then the horizontal wind speed affects the change of the final velocity of the raindrops under the effect of only the horizontal wind stress and the air drag force. The horizontal wind speed promotes the generation of the end of the raindrop. When the horizontal wind stress and the air drag force are balanced, the end of the raindrop level will reach a steady state in a short time. The greater the wind speed, the greater the end velocity. Through the above conclusions, the size and distribution of rainfall can be known, so that the weather conditions can be known in advance, and applications can be applied in agriculture and green living fields. In addition, if the principle of image acquisition is applied to the use of optical instruments to process raindrop images, it can play an extremely important role in meteorological science research.
