Typhoon Haiyan made landfall last week, causing much destruction in Southeast Asia. With death counts estimated to be in the thousands, this storm is one of the most powerful recorded typhoons to ever hit land and likely the deadliest natural disaster to hit the Philippines. So far, the typhoon is said to have affected at least 9.7 million people in 41 provinces. New satellite images obtained from NASA's Atmospheric Infrared Sounder (AIRS) instrument aboard NASA's Aqua spacecraft and the Indian Space Research Organization's OceanSAT-2 ocean wind scatterometer provide a glimpse into one of the most powerful storms ever recorded on Earth.

New satellite images obtained from NASA's Atmospheric Infrared Sounder (AIRS) instrument aboard NASA's Aqua spacecraft and the Indian Space Research Organization's OceanSAT-2 ocean wind scatterometer provide a glimpse into one of the most powerful storms ever recorded on Earth.
According to the U.S. Navy Joint Typhoon Warning Center, Typhoon Haiyan had maximum sustained winds of 195 mph (314 kilometers per hour), with gusts up to 235 mph (379 kilometers per hour) shortly before making landfall in the central Philippines on November 8.That would make it one of the strongest storms ever recorded. Weather officials in the Philippines reported the storm, known locally as Typhoon Yolanda, came ashore with maximum sustained winds of 147 mph (235 kilometers per hour) and gusts of up to 170 mph (275 miles per hour).
The two AIRS images, acquired at 8:59 p.m. PST on Nov. 7 and 9:17 a.m. PST on Nov. 8, show the powerful storm in infrared. When the first image was acquired, the storm was located 214 miles (344 kilometers) south-southeast of Manila. By the time the second image was acquired, the fast-moving storm was already centered west of the Philippines, on a forecast track that has headed towards Vietnam. The storm's coldest cloud-top temperatures are indicated by the brightest shades of purple, and show where Haiyan's heaviest rainfall was occurring.
Another image, from the OSCAT radar scatterometer on the Indian Space Research Organization's OceanSAT-2 satellite, shows Haiyan's ocean surface winds at 5:30 p.m. PST on Nov. 6. The wind data were calculated by scientists at NASA's Jet Propulsion Laboratory, Pasadena, Calif., using an advanced wind retrieval algorithm designed for tropical cyclone conditions. The colors indicate wind speed and arrows indicate wind direction. The wind speeds were measured in 15-by-15-mile (24-by-24-kilometer) boxes that recorded a maximum value of 128 miles, or 206 kilometers, per hour). That's why these wind speeds are lower than the maximum small-scale winds calculated by the U.S. Navy Joint Typhoon Warning Center.
