热带宽度加速扩张根据全球变暖的趋势,研究人员已预测地球热带将会不断扩张,但最新研究显示,热带区域扩张的速度超过预期。热带快速扩张会给地球带来更多极端灾害天气。我们知道,地球上的五带实际上是根据天文因素划分的,即按照地球公转时地轴与轨道面存在倾角而导致太阳直射点在赤道南北徘徊的这一特性划分。一般而言,热带是指地球上南纬23.5度和北纬23.5度之间的区域。但美国国家海洋和大气管理局实验室的科学家戴安·塞德尔等人在《自然-地球科学》上发
Accelerated Expansion of Tropical Width According to the global warming trend, researchers have predicted that the Earth’s tropics will continue to expand, but recent studies have shown that tropical regions have expanded faster than expected. Rapid tropical expansion will bring more extreme weather to the Earth. We know that the five bands on earth are actually divided according to astronomical factors, that is, according to the inclination of the earth’s axis and the orbital surface during the earth’s revolution, this characteristic division of the sun’s direct point at the equatorial north and south. In general, the tropics refer to the region between 23.5 degrees south latitude and 23.5 degrees north latitude on the earth. However, the scientist of the National Oceanic and Atmospheric Administration of the United States, Dian Seidel and others, issued the book on Nature-Earth Science.
