NASA sees Sanba develop into a super typhoon

September 13, 2012 ASIATropical Storm Sanba exploded in intensity between Sept. 12 and 13, becoming a major Category 4 Typhoon on the Saffir-Simpson Scale. NASA’s Aqua satellite captured infrared data that showed a large area of powerful thunderstorms around the center of circulation, dropping heavy rain over the western North Pacific Ocean. NASA’s Aqua satellite passed over Super Typhoon Sanba on Sept. 13 at 0447 UTC (12:47 a.m. EDT). The Atmospheric Infrared Sounder (AIRS) instrument captured an infrared image of Sanba and found an eye about 20 nautical miles (23 miles/37 km) wide, surrounded by a thick area of strong convection (rising air that forms the thunderstorms that make up the storm) and strong thunderstorms. Forecasters at the Joint Typhoon Warning center noted that the AIRS imagery showed that there was “no banding outside of this ring, consistent with an annular typhoon.” On Sept. 13 at 1500 UTC (11 a.m. EDT), Sanba’s maximum sustained winds were near 135 knots (155 mph/250 kmh). Sanba had higher gusts into the Category 5 typhoon category. The Saffir-Simpson scale was slightly revised earlier in 2012, so a Category 4 typhoon/hurricane has maximum sustained winds from 113 to 136 knots (130 to 156 mph /209 to 251 kmh). A Category 5 typhoon’s maximum sustained winds begin at 137 knots (157 mph /252 kmh). Sanba was located about 600 nautical miles (690 miles/1,111 km) south of Kadena Air Base, near 16.8 North latitude and 129.5 East longitude. It was moving to the north at 9 knots (10.3 mph/16.6 kmh) and generating wave heights of 40 feet. Sanba is expected to continue on a north-northwesterly track through the western North Pacific and move through the East China Sea, passing close to Kadena Air Base, Okinawa, Japan on Sept. 15. –Physics

    I am happy I am not there

    My husband and I are living in South Korea right now, and it looks like another typhoon is coming our way. Lord, be with all the people affected by this storm!

    It seems to be one thing or another for this area of the planet. The human and economic toll ihas been staggering. Damage to Okinawa will bring an economic burden to Japan that they don’t need at this time. I don’t think Japan can handle another catastrophic event, nor is the Western world in a postion to keep sending aid. China is now feeling the effects of living on the “bubble” and may be in a worse position than they let on. It is the season of economic collapse if history holds true. It would be a very unsettling time to be alive with out Faith.

    Any1 know if it’s true that experts can tell the difference between a storm created by nature & one created by HAARP? If so, any word yet on what spawned this thing? Sounds like it’s gonna be a doozy…the last thing that area needs right now. I hope those living in the area know that people around the world are praying for their safety. My heart goes out to them…they can’t seem to recover from 1 disaster & another 1 is always on the way.

    I was reviewing your introduction to Hazard, Japan has 50 nuclear reactors, not good! 😦

    As I was reading this article, The Weather Channel was showing the radar image of this typhoon. the wind speed is currently at 170mph (sorry don’t know kph) and it’s massive. My prayers are going out to everyone who is living in the path of this storm.
