You may have heard people discussing El Niño and its potential effects on various aspects of life. However, if you’re like many of us, you may have only a vague understanding of El Niño and how it can influence various factors. In this article, we will explain what El Niño is, how it alters weather patterns, and how these changes can increase the risk of pest infestations during El Niño years in New Zealand.
What is El Niño?
El Niño, which means “the little boy” in Spanish, was named by South American fishermen who observed warm water anomalies in the Pacific Ocean. This phenomenon often occurred around Christmas in South America, leading to the name El Niño de Navidad. Typically, trade winds near the equator in the Pacific Ocean blow westward, transporting warm water from South America towards Asia. Cold water rises from the depths to replace this warm water. However, during El Niño events, the trade winds weaken, causing warm water to shift back towards North and South America.
El Niño is a recurring weather pattern that irregularly takes place every two to seven years and can persist for 9 to 12 months or even longer. Scientists are still studying how climate change may impact the patterns of El Niño in New Zealand.
El Niño’s Impact on New Zealand
While New Zealand is surrounded by three distinct oceans—the Tasman Sea, the Southern Ocean, and the Pacific Ocean—it’s essential to recognize that all of the world’s oceans are interconnected. Therefore, a weather phenomenon affecting one ocean can have repercussions elsewhere.
In New Zealand, El Niño typically leads to higher temperatures across the entire country and reduced rainfall, particularly in the eastern and northern regions bordering the Pacific Ocean. These hotter and drier conditions increase the likelihood of heatwaves, droughts, and wildfires. While El Niño doesn’t guarantee these conditions, many of New Zealand’s significant droughts have coincided with El Niño events.
El Niño’s Impact on Pests in New Zealand
The severity of El Niño’s influence on local weather plays a crucial role in how it affects pests in New Zealand. In general, during hotter and drier weather, pests may seek refuge indoors to escape the heat and, more importantly, to find water. This behavior is especially pronounced if their natural habitats are affected by wildfires. Consequently, you can anticipate an uptick in pest infestations in New Zealand homes and businesses.
Some people may hope that El Niño’s drier conditions will lead to a reduction in mosquito populations in New Zealand, as mosquitoes require water for breeding. While it’s true that mosquitoes need water, they don’t necessarily need large amounts of it. Even in drier conditions, they can find sufficient water sources to lay their eggs.
