The storm that became Typhoon Lingling strengthened very quickly in the Northwestern Pacific Ocean and infrared imagery from NASA revealed the powerful thunderstorms fueling that intensification.
Lingling formed on Sept. 2 as Tropical Depression 15W and strengthened quickly into a tropical storm and then a typhoon. Although Lingling is to the northeast of Luzon, northern Philippines, there are still some warning signals in effect on Sept. 3. Tropical cyclone wind signal #1 is in effect over the Luzon province of Batanes.
On Sept. 3 at 12:05 p.m. EDT (1405 UTC), the Moderate Imaging Spectroradiometer or MODIS instrument that flies aboard NASA’s Terra satellite used infrared light to analyze the strength of storms within the typhoon. NASA researches these storms to determine how they rapidly intensify, develop and behave.
Tropical cyclones are made of up hundreds of thunderstorms, and infrared data can show where the strongest storms are located. They can do that because infrared data provides temperature information, and the strongest thunderstorms that reach highest into the atmosphere have the coldest cloud top temperatures.
MODIS found those strongest storms were northeast and southeast of the center of circulation where cloud top temperatures were as cold as minus 80 degrees Fahrenheit (minus 62.2 Celsius). NASA research has found that cloud top temperatures that cold indicate strong storms with the potential to generate heavy rainfall. READ MORE…
