엘니뇨가 펜실베이니아의 겨울 날씨에 영향을 미칠까요?

펜실베이니아의 겨울을 맞이할 준비가 되셨나요? 단풍이 들고 기온이 떨어지면서 많은 펜실베이니아 주민들이 어떤 겨울 날씨가 예상되는지 궁금해하고 있습니다. 엘니뇨가 다가오는 계절에 어떤 영향을 미칠지 미국 국립해양대기청 기후예측센터의 전문가에게 알아보세요.

엘니뇨 발생

엘니뇨와 이에 대응하는 라니냐는 태평양을 중심으로 발생하는 흥미로운 기후 패턴입니다. 정상적인 조건에서는 태평양 무역풍이 서쪽으로 불어 남아공의 따뜻한 물이 아시아로 향합니다. 따뜻한 물을 대체하기 위해 더 차가운 물이 용승 현상을 통해 상승합니다. 하지만 엘니뇨가 발생하면 이러한 중요한 무역풍이 약해져 따뜻한 물이 동쪽으로 밀려나 북미와 남미의 서해안으로 이동하는 역전 현상이 발생합니다. 이 미묘해 보이는 변화는 중대한 결과를 초래할 수 있습니다.

엘니뇨의 날씨 영향

엘니뇨의 영향은 태평양 너머까지 미칩니다. 이 광활한 바다의 따뜻한 물은 전 세계의 기온, 강우량, 악천후를 조절하는 제트 기류와 기후 시스템을 교란시킬 수 있습니다. 또한 엘니뇨 패턴은 태평양 생태계가 의존하는 차갑고 영양분이 풍부한 물을 빼앗아 갈 수 있습니다. 흥미롭게도 스페인어로 '어린 소년'을 뜻하는 '엘니뇨'라는 용어는 1600년대 남미의 관찰력이 뛰어난 어부들이 이 해양 현상이 12월경에 정점에 이르는 것을 발견하면서 만들어졌습니다.

펜실베이니아의 겨울 날씨 전망

그렇다면 올겨울 펜실베이니아에서 엘니뇨는 어떤 의미일까요? 기후 예측 센터에 따르면 미국 북부는 이번 겨울에 더 온화하고 건조한 겨울을 보낼 가능성이 높습니다. 10월, 11월, 12월에는 펜실베이니아의 평균 기온이 평년보다 높을 것으로 예상됩니다. 펜실베이니아주의 일부 지역은 늦가을과 초겨울에 더 습할 수 있지만, 다른 지역은 강수량이 평년보다 적을 수 있습니다. 하지만 평균 이상의 기온이 반드시 눈이 내리지 않는다는 것을 의미하지는 않는다는 점에 유의하세요. 과거 데이터에 따르면 펜실베이니아는 엘니뇨 패턴이 나타나는 겨울에 눈이 내렸던 적이 있습니다.

Non-contact exposure to dinotefuran disrupts honey bee homing by altering MagR and Cry2 gene expression

Non-contact exposure to dinotefuran disrupts honey bee homing by altering MagR and Cry2 gene expression Dinotefuran is known to negatively affect honeybee ( Apis mellifera ) behavior, but the underlying mechanism remains unclear. The magnetoreceptor ( MagR , which responds to magnetic fields) and cryptochrome ( Cry2 , which is sensitive to light) genes are considered to play important roles in honey bees’ homing and localization behaviors. Our study found that dinotefuran, even without direct contact, can act like a magnet, significantly altering MagR expression in honeybees. This non-contact exposure reduced the bees’ homing rate. In further experiments, we exposed foragers to light and magnetic fields, the MagR gene responded to magnetic fields only in the presence of light, with Cry 2 playing a key switching role in the magnetic field receptor mechanism ( MagR–Cry2 ). Yeast two-hybrid and BiFc assays confirmed an interactio...

“Global honey crisis”: Testing technology and local sourcing soars amid fraud and tampering concerns

“Global honey crisis”: Testing technology and local sourcing soars amid fraud and tampering concerns The World Beekeeping Awards will not grant a prize for honey next year due to the “inability” to thoroughly test honey for adulteration. The announcement comes amid the rise of honey fraud in the EU, where a 2023 investigation found that 46% of 147 honey samples tested were likely contaminated with low-cost plant syrups. Apimondia, the International Federation of Beekeepers’ Associations, organizes the event at its Congress, whose 49th edition will be held in Copenhagen, Denmark, in September 2025. The conference brings together beekeepers, scientists and other stakeholders. “We will celebrate honey in many ways at the Congress, but honey will no longer be a category, and thus, there will be no honey judging in the World Beekeeping Awards. The lessons learned from Canada 2019 and Chile 2023 were that adequate testing was impossible if we are to award winning honey at the Con...

Unveiling the Canopy's Secrets: New Bee Species Discovered in the Pacific

Unveiling the Canopy's Secrets: New Bee Species Discovered in the Pacific In an exciting development for environmentalists and beekeeping experts, researchers have discovered eight new species of masked bees in the Pacific Islands, shining a light on the rich biodiversity hidden within the forest canopy. This discovery underscores the critical role bees play in our ecosystems and the pressing need for conservation efforts to protect these vital pollinators. A New Frontier in Bee Research By exploring the forest canopy, scientists have opened a new frontier in bee research, revealing species that have adapted to life high above the ground. These discoveries are crucial for understanding the complex relationships between bees, flora, and the broader ecosystem. The new species of masked bees, characterized by their striking black bodies with yellow or white highlights, particularly on their faces, rely exclusively on the forest canopy for survival.

New Report – Interlocked: Midwives and the Climate Crisis

New Report – Interlocked: Midwives and the Climate Crisis Earlier this year, midwives from 41 countries shared their experiences of working in communities affected by climate change through our survey, Midwives’ Experiences and Perspectives on Climate Change. Their voices shaped our new report, Interlocked: Midwives and the Climate Crisis , which highlights how midwives are already responding to the health impacts of climate disasters like floods, wildfires, and extreme heat—and why they must be included in climate action plans. What did we learn?Climate change is damaging community health: 75% of midwives reported that climate change is harming the communities they serve, with rising rates of preterm births, food insecurity, and restricted access to care during disasters like floods. Midwives are critical first responders: Midwives are often the first and only healthcare providers on the ground in crises, delivering care during wildfires, floods, and extreme heat. Midwives face signi...

Bee attack claims life of newspaper distributor

Bee attack claims life of newspaper distributor Newspaper distributor Pushparaja Shetty (45), who sustained severe injuries in a bee attack, succumbed to his injuries on Thursday at a hospital in Mangaluru. Pushparaja was attacked by a swarm of bees on Wednesday morning while walking at Kenjaru Taangadi under Bajpe town panchayat limits. He was immediately admitted to a hospital for treatment but could not survive the ordeal. Fondly known as ‘Boggu’ in the Porkodi area, Pushparaja was well-known for his dedication to delivering newspapers on foot to every household. He was admired for his generosity, as he often distributed sweets to schoolchildren on Independence Day using his own earnings and contributed part of his income to the betterment of society. Pushparaja was unmarried and is survived by three brothers and one sister.

Start the New Year Humming Like a Bee

Start the New Year Humming Like a Bee There are lots of opportunities to be as busy as a bee during these winter holidays. As we hustle toward the dawn of the New Year, it can be hard to notice that the natural world is actually suggesting something different for us right now. We’re past the solstice, but the winter still stretches ahead, the days are still short and the nights long. We’re being invited into a quieter, more inner-focused time. The ancient yogis were all about this inner focus. In India, for example, the Upanishads, the Sanskrit writings that accompanied the development of Hinduism — and alongside it, yoga — beginning around 800 B.C.E., went deeper than earlier texts had into philosophy and questions of being. With the goals of increased inner awareness and higher consciousness, yoga was at that time not yet as focused on the body or on asanas, as it now can tend to be. But the yogis did develop many practices to try to open the way to those goals. They discovered...

The largest “killer hornets” in the world were exterminated in the US

The largest “killer hornets” in the world were exterminated in the US The US informed that it had exterminated the worldʼs largest hornets, nicknamed "killer hornets" — they are capable of occupying a hive of honey bees in just 90 minutes, decapitating all its inhabitants and feeding their offspring to their own. This was reported by the Department of Agriculture in Washington. The hornets, which can reach five centimeters in length, were previously called Asian giant hornets, but in 2019 they were also spotted in Washington state near the Canadian border. In China, these insects killed 42 people and seriously injured 1,675. A dead northern giant hornet (below) next to a native bald hornet. According to experts, the hornets could have entered North America in plant pots or shipping containers. The hornet can sting through most beekeeper suits because it produces nearly seven times more venom than a honeybee and stings multiple times. Thatʼs why the Washington Departme...

The Unexpected Surge: America's Honeybees Buzz Back to Record Numbers

The Unexpected Surge: America's Honeybees Buzz Back to Record Numbers In an age where environmental narratives often lean towards loss and decline, the story of the American honeybee offers a glimmer of hope and a puzzle to solve. Recent data from the Census of Agriculture reveals an astonishing rebound in the honeybee population, now soaring to an all-time high of 3.8 million colonies. This revelation comes as a surprise against the backdrop of two decades marked by fears of colony collapse and the potential ramifications for ecosystems and agriculture. The surge in bee populations brings to light a series of questions and insights into the intertwined worlds of agriculture, conservation, and legislation. Central to this narrative is the state of Texas, where legislative changes have catalyzed a beekeeping boom by offering agricultural tax breaks to landowners cultivating honeybees. This policy shift, coupled with the entrepreneurial spirit of Texans and the essential role of bees...
