Himawari-8 Water Vapor (6.9 \u00b5m) images [click to play animation<\/p><\/div>Japanese Meteorological Agency<\/a><\/strong> Himawari-8 Water Vapor (6.9 \u00b5m, 2-km resolution)<\/em> images (above)<\/strong><\/em> showed the rapid intensification of a hurricane-force extratropical cyclone over the North Pacific Ocean and Bering Sea during the 12 December – 13 December 2015 period. The 6.9 \u00b5m is one of 3 water vapor spectral bands on the Himawari AHI<\/strong><\/a> instrument — GOES-R<\/strong><\/a> will feature 3 nearly identical water vapor bands on the ABI<\/strong><\/a> instrument.<\/p>\n

According to surface analyses<\/strong><\/a> from the Ocean Prediction Center<\/strong><\/a>, the storm was centered over Japan at 00 UTC on 11 December, and began rapidly intensifying later that day as it continued moving northeastward; it eventually deepened to a minimum central pressure of 924 hPa (27.29 inches of mercury) over the far southern Bering Sea at 06 UTC<\/strong><\/a> on 13 December. This equaled the analyzed minimum central pressure of Post-Tropical Cyclone Nuri<\/strong><\/a> in November 2014, which was one of the strongest storms on record in the Bering Sea.<\/p>\n

Corresponding GOES-15 Water Vapor (6.5 \u00b5m, 4-km resolution)<\/em> images (below)<\/strong><\/em> offered a slightly closer view of the intensifying storm. The unique satellite signature — resembling a curved scorpion tail — of a phenomenon known as a sting jet<\/strong><\/a> was seen to begin developing around 20 UTC<\/strong><\/a> on 12 December south of the Aleutian Islands. Several hours after the middle-tropospheric sting jet feature on water vapor imagery moved over Adak Island (PADK on the images) around 0130 UTC<\/strong><\/a>, sustained surface winds of 82 knots (94 mph) with gusts to 106 knots (122 mph) were recorded just after 09 UTC. According a Tweet<\/strong><\/a> from the Ocean Prediction Center, winds from the storm also produced wave heights of 63 feet.<\/p>\n
