What is the North American heat dome and how dangerous is it?
什麼是北美"熱蓋現象"，並且有多危險呢?
Tract 大片土地
Sweltering 熱極了
Atmospheric Pressure 大氣壓力
Heat Wave 熱浪
Heatstroke 中暑
Delirium 神智不清/語無倫次
Seizure 癲癇發作
Susceptible 易受影響
Huge tracts of North America are sweltering under very high temperatures, which are close to 50ºC in some places. The phenomenon behind this weather is known as a heat dome and the one that's currently settled across parts of Canada and the US is feared to have caused the death toll to rise in British Columbia.
一大片的北美地區在高溫之下熱得難受，有些地方接近攝氏50度。這種天氣現象稱作"熱蓋現象"，而且目前在加拿大和美國部分地區出現的"熱蓋現象"，可能導致不列顛哥倫比亞省的死亡人數上升。
1. What is a heat dome and what causes it?
1.什麼是”熱蓋現象”而什麼會引起?
There are two things that contribute to a heat dome – atmospheric pressure and rising sea temperatures.
有兩個因素會導致"熱蓋現象"-大氣壓力和不斷上升的海水溫度。
2. What effect is the heat dome having?
2.”熱蓋現象”會導致什麼結果?
One of the biggest health risks in a heat wave such as this one is heatstroke. Unless detected and treated promptly, heatstroke can lead to many serious problems including damage to the brain, heart, muscles and internal organs. Commonly accompanied by feelings of confusion and delirium, heatstroke can trigger seizures and lead to comas, brought on by swelling of the brain and organs.
像這樣的熱浪中，最大的健康風險之一就是中暑。除非及時發現並治療，中暑可能會導致許多嚴重問題，包括對大腦、心臟、肌肉和內臟器官的損害。通常還會伴隨意識模糊和語無倫次，中暑也會因為大腦和器官腫脹，進而引發癲癇發作並造成昏迷。
Older people are more susceptible to heatstroke, as the body’s ability to regulate heat deteriorates with age.
隨著年紀增長，身體調節熱能的能力會下降，因此老年人更容易中暑。
