At 1500 on 9 October, the Joint Typhoon Warning Center<\/a> stated that Super Typhoon Habigis had sustained winds of 140knts or 161.1092 mph<\/a>. This is the equivalent of a Category 5<\/strong> storm in the Atlantic basin.<\/p>\n

\"\"<\/a><\/p>\n

The Regional Specialized Meteorological Center (RSMC) Tokyo stated that the maximum winds at the center were 105knts (~120mph). The difference is due to differing methods of determining the winds and due to the fact that JTWC adopts a 1 min mean wind speed, but RSMC Tokyo adopts 10 mins mean wind speed.<\/p>\n

\"\"<\/a><\/p>\n

While this doesn’t affect forecasts for this storm, this sort of difference in measurement could mean the difference between a tropical storm warning or a high wind warning, as has been seen in some previous instances as storms transition from the Central Pacific to the RMSC Tokyo or other areas of responsibility.<\/p>\n

S-NPP first saw Super Typhoon Habigis at 1536Z on the western part of the pass, leading to an oblong effect of the eye, which the waxing moon (83% illumination) cast into shadow. This meant that any features that were in the eye itself could not really be seen .In addition, there was a lone lightning strike that could be seen in the S-NPP imagery.<\/p>\n\n\t\n\t\t\n\t\t\t<\/polyline>\n\t\t\t<\/polyline>\n\t\t\t<\/polyline>\n\t\t\t<\/polyline>\n\t\t\t<\/svg>\n\t\t<\/span>\n\t<\/span>\n<\/div>\n\n\n

However both the moonlit imagery from the DNB and the I05 (11\u03bcm) imagery showed what you’d expect of an intense tropical cyclone: a well defined eye along with copious amounts of tropospheric gravity waves as well as some intense convection in the feeder bands.<\/p>\n\n\t\n\t\t\n\t\t\t<\/polyline>\n\t\t\t<\/polyline>\n\t\t\t<\/polyline>\n\t\t\t<\/polyline>\n\t\t\t<\/svg>\n\t\t<\/span>\n\t<\/span>\n<\/div>\n\n\n

Just under an hour later, GCOM-W1 passed with a near nadir overpass of Habigis, allowing the AMSR2 instrument to looking to the storm. The 88.9GHz imagery showed a wide circulation, similar to the IR imagery and ATMS imagery from NOAA-20 about 3 minutes later.<\/p>\n\n\t\n\t\t\n\t\t\t<\/polyline>\n\t\t\t<\/polyline>\n\t\t\t<\/polyline>\n\t\t\t<\/polyline>\n\t\t\t<\/svg>\n\t\t<\/span>\n\t<\/span>\n<\/div>\n\n\n

However, the 23.8Ghz showed the center of circulation was not exactly at the center of the IR or 88.9GHz circulation.<\/p>\n\n\t\n\t\t\n\t\t\t<\/polyline>\n\t\t\t<\/polyline>\n\t\t\t<\/polyline>\n\t\t\t<\/polyline>\n\t\t\t<\/svg>\n\t\t<\/span>\n\t<\/span>\n<\/div>\n\n\n

Also note the double eye in the 88.9Ghz AMSR2 data, possibly indicating an eyewall replacement either being underway or having taken place.<\/p>\n

\"\"<\/a><\/p>\n

The I05 (11\u03bcm) imagery from NOAA-20 again showed similar features to the NPP imagery 50 minutes prior, though with the almost-nadir overpass, features were a bit less affected by parallax.<\/p>\n\n\t\n\t\t\n\t\t\t<\/polyline>\n\t\t\t<\/polyline>\n\t\t\t<\/polyline>\n\t\t\t<\/polyline>\n\t\t\t<\/svg>\n\t\t<\/span>\n\t<\/span>\n<\/div>\n\n\n

\"\"<\/a><\/p>\n

One other feature of the NOAA-20 pass is that the eye was not completely in shadow, with some mesovorticies within the eye, again a feature of an intense system. This can easily be seen in the zoomed in imagery of the eye.<\/p>\n\n\t\n\t\t\n\t\t\t<\/polyline>\n\t\t\t<\/polyline>\n\t\t\t<\/polyline>\n\t\t\t<\/polyline>\n\t\t\t<\/svg>\n\t\t<\/span>\n\t<\/span>\n<\/div>\n\n\n

The forecast from JTWC and JMA continue to have it impacting Japan on 12 October. This is enough of a concern that the Rugby World Cup has cancelled the (important) match between Japan and Scotland on that day due to weather concerns from Habigis, meaning the match is a draw, with Japan advancing to the quarter-finals.<\/p>\n
