There are actually 9 types of precipitation
Most of us generally think of precipitation in terms of three varieties: rain, snow, and sleet. But for meteorologists and climate scientists, the trio is far from adequate. In fact, a team of researchers including NASA engineers spent almost a decade analyzing weather data to fine-tune these categories. After utilizing machine learning to digest the ensuing mountains of data, the group has put forth a total of nine different types of precipitat…
Between rain and snow, machine learning finds nine precipitation types
In research that could improve weather forecasting and winter driving safety, a University of Michigan-led study distinguished nine distinct precipitation types—varieties of rain, snow and mixed-phase (e.g., sleet)—using unsupervised machine learning and nearly a decade's worth of high-speed camera data. The research is published in Science Advances.
As part of research to improve weather forecasting and the safety of winter driving, a study conducted by the University of Michigan identified nine distinct types of precipitation: rain, snow and mixed phases (e.g., scissors) – using unsupervised machine learning and nearly a decade of large camera data [...]
