美国气象频道有业内人士发文专门介绍森拉克及镜像气旋迈拉与厄尔尼诺的关联及影响
Cyclone Maila and Typhoon Sinlaku, a pair of twin tropical cyclones in the Pacific, could thrust forward the formation of an El Niño while bringing impacts to Oceania and Guam.
The two systems, Maila and Sinlaku, make up a pair of tropical cyclones that formed on opposite sides of the equator, known as twin cyclones.
This phenomenon is unheard of in the Atlantic, but is much more common in the western Pacific and Indian Oceans, which host favorable conditions for tropical systems both north and south of the equator. In the south Atlantic, tropical systems don’t form close to the equator and form rarely at all in that basin. In the Pacific, twins can form as often as 2-3 times a year.
They form when a burst of wind and moisture moving eastward at low latitudes is split in half by the equator. The resulting storms will be mirror images of each other and will spin in opposite directions.
Indirectly and with a significant delay, these two cyclones could have impacts around the world by this summer long after they’ve dissipated.
The wind burst that helped them form and the additional eastward flow created by the twins will likely help intensify this year’s expected El Niño.
These strong winds will push warm water located between Hawaii and New Guinea eastward toward South America, helping trigger the formation of El Niño later this year.
Once this process begins, it becomes difficult to stop. When the eastern Pacific is engulfed in warmer water, thunderstorms begin to form, which tends to pull in more wind from Oceania. This spurs more thunderstorm activity and so the loop begins. This is called the Bjerknes feedback loop. |
