"Temperature and Precipitation in a Nuclear Winter"

In a nuclear winter, widespread nuclear explosions release massive amounts of smoke, soot, and dust into the atmosphere, blocking sunlight. This core process leads to significant drops in surface temperatures (colder weather) and reduces rainfall (precipitation). The decreased sunlight prevents plants from growing, which then disrupts food chains. The overall climate becomes colder and drier for an extended period, impacting ecosystems, agriculture, and human survival. These atmospheric changes can persist for months or years, resembling a prolonged winter scenario caused by the widespread fallout from nuclear warfare.
