Understanding Climate Trends During Hurricane Season

Hurricane season in the United States, officially running from June 1 to November 30, is a period of heightened vigilance for coastal and southeastern regions. Understanding the climate trends that influence hurricane activity is crucial for preparedness and response.

What Are the Key Climate Patterns Affecting Hurricane Season?

Two primary climate phenomena significantly impact hurricane activity:

• El Niño and La Niña: These are opposite phases of the El Niño-Southern Oscillation (ENSO). El Niño is characterized by warmer-than-average sea surface temperatures in the central and eastern Pacific Ocean, while La Niña features cooler-than-average temperatures. These conditions can alter atmospheric patterns, affecting hurricane formation and trajectories.

How Do El Niño and La Niña Influence Hurricane Activity?

• El Niño: Typically suppresses Atlantic hurricane activity by increasing vertical wind shear, which disrupts storm development.

• La Niña: Generally enhances Atlantic hurricane activity by decreasing vertical wind shear, creating more favorable conditions for storm formation.

What Are the Historical Trends in Hurricane Activity?

Historical data indicates that the number of hurricanes and major hurricanes making landfall in the U.S. has remained relatively stable over the past century. However, the intensity of storms has shown variability, with periods of increased activity. For instance, the late 20th century saw a rise in hurricane intensity, aligning with warmer sea surface temperatures. (19january2021snapshot.epa.gov)

How Does Climate Change Affect Hurricane Trends?

Climate change is expected to influence hurricane activity in several ways:

• Sea Surface Temperatures: Rising global temperatures can lead to warmer ocean waters, providing more energy for storms and potentially increasing their intensity.

• Storm Intensity: Models project that for every 1°C increase in sea surface temperature, wind speeds of hurricanes could strengthen by about 4%. (climate.gov)
