The classic question of whether one should walk or run in the rain to remain the least wet has inspired a myriad of solutions ranging from physically performing test runs in raining conditions to mathematically modeling human movement through rain. This manuscript approaches the classical problem by simulating movement through rainfall using MATLAB. Our simulation was generalizable to include snowfall as well. An increase in walking speed resulted in a corresponding decrease in raindrop and snowflake collisions. When raindrops or snowflakes were given a horizontal movement vector due to wind, a local minimum in collisions was achieved when moving in parallel with the same horizontal speed as the raindrop; no local minimum was detected with antiparallel movement. In general, our simulation revealed that the faster one moves, the drier one remains.

使用 MATLAB 模拟雨雪中移动时的最佳干燥度

一个人应该在雨中行走还是跑步以保持最少的湿气这个经典问题激发了无数的解决方案，从在下雨条件下进行物理测试运行到对雨中人体运动进行数学建模。本手稿通过使用 MATLAB 模拟降雨过程中的运动来解决经典问题。我们的模拟也可以推广到降雪。步行速度的增加导致雨滴和雪花碰撞的相应减少。当雨滴或雪花由于风而被给予水平运动矢量时，当以与雨滴相同的水平速度平行运动时，碰撞达到局部最小值；反平行运动未检测到局部最小值。一般来说，我们的模拟显示，移动得越快，保持得越干燥。
