描述Kilo, Ignacio and Jimena 2015-08-30 0930Z.jpg |
English: Hurricanes traversing the Pacific Ocean are often solitary storms. Occasionally they show up in pairs. But according to meteorologists, August 2015 marked the first time in recorded history that three Category 4 storms simultaneously paraded over the central and eastern Pacific.
The top image shows a nighttime view of hurricanes Kilo, Ignacio, and Jimena (from west to east). The image is a mosaic, based on data collected during three orbital passes of the Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi-NPP satellite. The VIIRS “day-night band” detects light in a range of wavelengths from green to near-infrared, and uses light intensification to enable the detection of dim signals. Moonlight from a full Moon was favorable for these nighttime images, acquired between 11:30 p.m. and 3 a.m. Hawaii Standard Time on August 29-30 (09:30 and 13:00 Universal Time on August 30). At the time, all three hurricanes were Category 4 storms—the second-highest ranking on the Saffir-Simpson Hurricane Wind Scale. Hurricane Kilo had maximum sustained winds of 215 kilometers (135 miles) per hour, according to an advisory issued by the Central Pacific Hurricane Center. The storm moved toward the north-northwest, and posed no hazards to land. Meanwhile, Hurricane Ignacio had similar sustained wind speeds that measured 220 kilometers (140 miles) per hour; this storm, however, was closer to the Big Island’s mainland and had the potential to produce damaging and life-threatening surf. Huricane Jimena, the easternmost of the three storms, carried maximum sustained winds of about 210 kilometers (130 miles) per hour, according to an advisory issued by the National Hurricane Center. |
