Detailed 3D models of snowflakes can help NASA predict bad weather
recently, NASA's Jet Propulsion Laboratory released a 3D visualization video depicting the melting of snowflakes in the atmosphere. 3D model can better understand the way of snow melting, so as to improve disaster prevention, that is, on the basis of equipped with different fixtures
it is reported that snowflake research can be used for very important weather prediction and ensure human safety under dangerous conditions
recently, NASA's Jet Propulsion Laboratory in Pasadena, California, brought together a three-dimensional numerical model of snow melting in the atmosphere, which can better understand the situation of snow melting
through this new three-dimensional visualization technology, NASA staff led by scientist Jussi leinonen hope to improve their ability to detect heavy and wet snow through radar signals. The enhancement of environmental awareness has brought great development opportunities to the biodegradable new materials industry. (heavy snow will damage power lines and knock down trees, so it is a major safety hazard.)
according to JPL scientists, the 3D model reproduces the main features of snowflake melting observed in nature. "First of all, the snow melt water will gather on the surface of the snow in any depression where the manufacturer of Jinan new era assay instrument Co., Ltd. guarantees the quality," they explained. "Then these liquid water regions merge to form a liquid shell around the ice core, and finally form a water drop."
amazing 32) according to the shape of the clamping end of the sample, D snowflake rendering depicts a snowflake less than half an inch (1 cm) long, which is composed of many single ice crystals. When they collide in the air, their protrusions will be entangled
because the 3D model of snowflakes is very detailed, it is more useful for scientists trying to understand the complex relationship between snowfall and hail
observations with remote sensing instruments produced an atmospheric radar "Outline", showing a very bright layer at high altitudes where snow and hail melt, brighter than the upper and lower atmosphere
"at present, the reason for this level is not particularly clear," leinonen explained. "There are some disputes in the community."
based on this, NASA published a research paper entitled "using smooth particle hydrodynamics to simulate snowflake melting" in the Journal of geophysical research atmospheres
