Did El Niño turn Hurricane Polo into the most powerful storm of the season?
厄尔尼诺现象是否使波罗飓风成为本季最强大的风暴？
Hurricane Polo, a large storm off the coast of Mexico, has been downgraded to category 4 but remains "very powerful", the US National Hurricane Center said.
美国国家飓风中心表示，墨西哥海岸附近的飓风波罗已被降级为 4 级，但仍然“非常强大”。
The Pacific hurricane, one of the strongest of the season, was projected to head towards the coast of south-western Mexico, bringing intense wind and rain, though was not expected to make landfall.
太平洋飓风是本季最强飓风之一，预计将向墨西哥西南部海岸移动，带来强风和降雨，但预计不会登陆。
A Hurricane Hunter aircraft, operated by the US National Oceanic and Atmospheric Administration (Noaa), flew into the storm on Tuesday and recorded sustained wind speeds near 180 mph (285 km/h), with stronger gusts.
美国国家海洋和大气管理局 (Noaa) 运营的一架飓风猎人飞机周二飞入风暴，记录到持续风速接近 180 英里/小时（285 公里/小时），阵风更强。
The slow-moving storm is being fuelled by extremely warm waters caused by the El Niño climate phenomenon.
厄尔尼诺气候现象造成的极度温暖的海水加剧了这场缓慢移动的风暴。
It was previously a category 5 storm - the highest level on the scale - but was downgraded to category 4 on Wednesday morning.
此前它是5级风暴——规模最高——但在周三早上被降级为4级。
Forecasters said that the storm was expected to fluctuate in intensity over the next few days.
预报员表示，预计未来几天风暴的强度将出现波动。
As it slowly drifts north west, Polo will drive torrential rainfall in parts of Mexico's south-west coast, and "may produce life-threatening flooding and mudslides, especially in areas of steep terrain," the forecaster said.
预报员表示，随着它缓慢向西北方向移动，“波罗”将给墨西哥西南海岸部分地区带来暴雨，并“可能引发危及生命的洪水和泥石流，特别是在地形陡峭的地区”。
Forecasters said heavy rainfall associated with Polo could impact coastal regions in southwest Mexico through Thursday.
预报员表示，与波罗相关的强降雨可能会影响墨西哥西南部沿海地区，直至周四。
A tropical storm warning remains in effect for portions of southwest Mexico and a tropical storm watch is in effect west of Playa Perula, the National Hurricane Center said.
国家飓风中心表示，墨西哥西南部部分地区的热带风暴警报仍然有效，普拉亚佩鲁拉以西的热带风暴监视也已生效。
The hurricane centre said people under a tropical storm warning should expect conditions to develop on Wednesday, and those in the watch areas can expect conditions to develop by Thursday.
飓风中心表示，受到热带风暴警告的人们应该预计周三会出现这种情况，而观察区的人们预计周四会出现这种情况。
Rainfall totals of up to 6in (15cm) are forecast, with 8in possible in some areas. Residents have also been warned of large ocean swells and life-threatening surf conditions for the next few days.
预计降雨量总计可达 6 英寸（15 厘米），部分地区可能达到 8 英寸。 居民们还收到警告，未来几天将出现巨浪和危及生命的冲浪状况。
"So far, the information we have is that (Polo) will not make a direct landfall on the coast," Mexico's President Claudia Sheinbaum said on Tuesday, but she warned residents along the Pacific coast to be vigilant. Sheinbaum highlighted the states of Jalisco, Colima and Michoacan as being at risk.
墨西哥总统克劳迪娅·谢因鲍姆周二表示：“到目前为止，我们掌握的信息是（波罗）不会直接在海岸登陆，”但她警告太平洋沿岸居民保持警惕。 谢因鲍姆强调哈利斯科州、科利马州和米却肯州面临风险。
So far this season, the Pacific has seen 15 storms, all in early September. Polo is the strongest of a batch of three storms currently swirling between Hawaii and the North American mainland.
本季节到目前为止，太平洋已发生 15 场风暴，全部发生在 9 月初。 波罗是目前在夏威夷和北美大陆之间盘旋的三场风暴中最强的一场。
Data from the Hurricane Hunter aircraft indicated that Polo could still strengthen, because of what NOAA called a "very conducive" environment of extremely warm ocean waters feeding the storm.
飓风猎人飞机的数据表明，波罗仍可能增强，因为美国国家海洋和大气管理局 (NOAA) 称，极其温暖的海水为风暴提供了“非常有利”的环境。

Daily sea surface temperatures in a key region of the central-eastern Pacific were 3.05C above average on 19 September - exceeding the previous record of 3.02C set during the very strong El Niño of 2015.
9 月 19 日，中东太平洋主要地区的每日海面温度比平均水平高出 3.05 摄氏度，超过了 2015 年强厄尔尼诺现象期间创下的 3.02 摄氏度的纪录。
Some longer-term measures of El Niño have not yet hit record levels but this is likely to change, with the peak not expected until later this year.
厄尔尼诺现象的一些长期指标尚未达到创纪录水平，但这种情况可能会改变，预计要到今年晚些时候才会达到峰值。
Warmer ocean waters mean storms can pick up more energy, leading to higher wind speeds.
海水变暖意味着风暴可以吸收更多能量，导致风速更高。
El Niño is a naturally-occurring pattern, which happens about every two to seven years and tends to last for around a year.
厄尔尼诺现象是一种自然发生的现象，大约每两到七年发生一次，通常会持续一年左右。
Trade winds that typically blow from east to west across the Pacific Ocean can weaken or even reverse, allowing warm water to spread eastwards.
通常从东向西吹过太平洋的信风可能会减弱甚至逆转，从而使温暖的海水向东扩散。
Heat is then released from the ocean into the atmosphere which can boost global temperatures and drive changes in weather patterns around the world.
然后热量从海洋释放到大气中，这可以提高全球气温并推动世界各地天气模式的变化。
