Navigating the Changing Winter Landscape in New Hampshire: El Niño and Climate Change
Navigating the Changing Winter Landscape in New Hampshire: El Niño and Climate Change
New Hampshire recently experienced a rollercoaster of weather, from a snowstorm to 50-degree temperatures, rain, and flooding. The unique fusion of an El Niño weather pattern and the effects of climate change, as explained by state climatologist Mary Stampone, is ushering in an enhanced warming this winter. In this article, we delve into the implications of this collision and its consequences for the Granite State.
Understanding El Niño and Climate Change El Niño and La Niña, opposing climate phenomena, disrupt normal conditions worldwide. El Niño, characterized by weak trade winds, influences seasonal weather on a hemispheric scale. In northern New England, El Niño historically brings warmth. This year marks the return of El Niño after four years, with NOAA predicting warmer-than-average temperatures in the northern U.S., including New England.
El Niño 'On Top' of General Warming Colliding with climate change, an El Niño winter can become more pronounced. Climate scientist Michelle L’Heureux highlights that climate change can exacerbate certain impacts related to El Niño. In New Hampshire, where winters are already warming faster than other seasons, the combined effect results in an even warmer winter. A 2022 analysis by Climate Central revealed a 3.3-degree Fahrenheit average warming across the U.S. since 1970, with New England experiencing a more drastic increase.
Impacts on Precipitation and Ski Resorts El Niño tends to make conditions wetter, contributing to increased precipitation. December in New Hampshire saw nearly double the normal amount of rain, causing historical river flooding events. Ski resorts in the state, facing warming trends, have invested in snowmaking technology for their viability. The warming winter trends have prompted closures and recovery efforts at resorts like Waterville Valley, Wildcat Mountain, and Loon Mountain.
Adapting to Changing Conditions Ski resorts in New Hampshire, recognizing the need for resilience, have invested in weatherproofing operations and efficient snowmaking equipment. Melody Nester from Ski New Hampshire emphasizes the importance of these investments to ensure continued operation in less-than-ideal weather conditions. While weather remains uncontrollable, strategic measures enable the mountains to adapt and compensate.
Conclusion As New Hampshire navigates this winter's unique fusion of El Niño and climate change, the warming trends and increased precipitation pose challenges for various sectors, especially ski resorts. Understanding these dynamics is crucial for adapting to changing conditions and ensuring the resilience of industries affected by the evolving winter landscape.
