scientists create first-ever 3-d model of a melting snowflake
Bookmarked 402 weeks ago
this visualization is based on the first three-dimensional numerical model of melting snowflakes in the atmosphere developed by scientist jussi leinonen of nasa039s jet propulsion laboratory in pasadena california a better understanding of how snow melts can help scientists recognize the signature in radar signals of heavier wetter snow -- the kind that breaks power lines and tree limbs -- and could be a step toward improving predictions of this hazardthe model reproduces key features of melting snowflakes that have been observed in nature: first meltwater gathers in any concave regions of the snowflake039s surface these liquid-water regions merge as they grow and eventually form a shell of liquid around an ice core finally developing into a water drop the visualization shows a typical snowflake less than half an inch one centimeter long the snowflake is composed of individual ice crystals whose arms became entangled when they collided in the air the extremities of the arms melt first b
