El Nino and Its Impacts

Meteorologist Stephen Abshire explains El Nino, a climate phenomenon involving warmer ocean temperatures in the Eastern Pacific, and its global impacts. El Nino affects weather patterns, causing variations in temperature and precipitation. The video discusses the transition from La Nina to El Nino, forecasts for the upcoming months, and potential impacts on hurricane activity and seasonal weather changes, particularly in the United States. The effects are more noticeable in winter, with changes in the jet stream and regional weather patterns.
