Niña, short for La Niña, is a climate pattern characterized by cooler ocean temperatures in the central and eastern Pacific Ocean. It is part of the larger El Niño-Southern Oscillation (ENSO) cycle, which influences global weather patterns. During a Niña event, the trade winds strengthen, leading to changes in precipitation and temperature across various regions. Typically, Niña can result in increased rainfall in some areas, such as Southeast Asia and Australia, while causing droughts in others, like the southern United States. These shifts can impact agriculture, water supply, and even hurricane activity in the Atlantic Ocean.
