Extreme wind and rain may lead to bigger and worse desert locust outbreaks, with human-caused climate change likely to intensify the weather patterns and cause higher outbreak risks, a new study has found.
极端的风和雨可能导致更大、更严重的沙漠蝗灾，而人为造成的气候变迁，可能会加剧这种天气模式，并增加蝗灾爆发的风险，一项新研究发现。
The desert locust — a short-horned species found in some dry areas of northern and eastern Africa, the Middle East, and South Asia — is a migratory insect that travels in swarms of millions over long distances and damages crops, causing famine and food insecurity. A square kilometer swarm comprises 80 million locusts that can in one day consume food crops enough to feed 35,000 people.
沙漠蝗虫是一种短角物种，分佈在非洲北部和东部、中东和南亚的一些干旱地区，是一种迁徙性的昆虫，以数百万只的群体迁徙长距离，破坏农作物，造成饥荒和粮食不安全。1平方公里的蝗群包含8000万只蝗虫，1天可以消耗足够养活3.5万人的粮食作物。
The study, published in Science Advances on Wednesday, said these outbreaks will be “increasingly hard to prevent and control” in a warming climate.
这项研究週三发表于《科学进展》期刊，指出在气候变暖的情况下，这些蝗灾将「越来越难以预防和控制」。

migratory：形容词，迁徙的（指候鸟或其他动物的季节性迁徙特征），（动物、候鸟或人）移居的，迁居的。例句：Sea eagles are not migratory, so once extinct, there is no chance of them returning naturally.（海鹰不是候鸟，所以一旦灭绝，就不会有同类从迁徙地自然回归原驻地的可能。）
swarm：名词，一大群（昆虫）。例句：Ronny was so focused on observing a swarm of ants that no one can disrupt him.（罗尼很专心观察一群蚂蚁，没人可以打断他。）
