Why is severe weather considered a density-independent factor?

Severe weather is considered a density-independent factor because its effects on a population do not depend on the population's size or density. Events like hurricanes, floods, or droughts can impact all individuals in an area regardless of how many there are, leading to widespread mortality or displacement. This means that whether a population is large or small, severe weather can equally influence its survival and reproduction rates. Thus, it acts independently of population dynamics.
