Snow

The emitter's attributes can be adjusted to control the speed, emission rate, spread, and other characteristics of the snowflakes. The snowflake particles will fall under the influence of a gravity field, creating the illusion of falling snow in your Maya scene.

This code creates a particle emitter that generates snowflake particles and uses a dynamic solver to simulate their movement. It also creates a gravity field to pull the particles downwards, simulating gravity's effect. The particle attributes such as speed, emission rate, and rendering style can be adjusted as per your requirements.
