When a nuclear explosion encounters rain and snow, due to the purification effect of rain and snow,

Rain and snow weather has played a very good role in nuclear radiation, especially reducing the risk of nuclear radiation spreading outward.

At the height of nuclear smoke cloud, the wind direction of each layer is different, and the diffusion range of smoke cloud is also different.

The high wind speed on the ground will produce dust and aggravate the air pollution on the ground.

Rain can wash down suspended dust and particles in the air, purify the air, wet the ground and reduce dust.
