NASA infrared imagery shows Hagupit nearing landfall in China

On Aug. 3 at 1:41 p.m. EDT (1741 UTC) NASA’s Aqua satellite analyzed Typhoon Hagupit less than 2 several hours right before landfall in China. Applying the Atmospheric Infrared Sounder or AIRS instrument, NASA observed coldest cloud prime temperatures as cold as or colder than (purple) minus 63 degrees Fahrenheit (minus 53 degrees Celsius).

NASA’s Aqua satellite presented a seem at Storm Hagupit as it was nearing landfall in southeastern China.1 of the means NASA researches tropical cyclones is employing infrared data that delivers temperature info. Cloud prime temperatures present information and facts to forecasters about exactly where the strongest storms are positioned within a tropical cyclone. Tropical cyclones do not often have uniform strength, and some sides have more powerful sides than others. The more powerful the storms, the greater they extend into the troposphere, and the colder the cloud temperatures.

On Aug. 3 at 1:41 p.m. EDT (1741 UTC) NASA’s Aqua satellite analyzed Hagupit using the Atmospheric Infrared Sounder or AIRS instrument. Aqua passed in excess of Hagupit a lot less than 2 hours right before its official landfall.

The infrared information showed the bulk of the storms had been southeast of the middle for the reason that of vertical wind shear or outdoors winds pushing in opposition to the storm from the northwest.

AIRS found coldest cloud prime temperatures as chilly as or colder than minus 63 levels Fahrenheit (minus 53 levels Celsius). NASA study has revealed that cloud major temperatures that cold suggest robust storms that have the functionality to build large rain.

China’s National Meteorological Heart documented that Hagupit produced landfall China’s Zhejiang province on the coastal regions of Yueqing Town at all over 3:30 a.m. neighborhood time on Aug. 4 (3:30 p.m. EDT on Aug 3). At the time of landfall, Hagupit experienced utmost sustained winds around 85 mph (137 kph), equal to a Classification 1 hurricane.

At 5 a.m. EDT (0900 UTC) on Aug. 4, the Joint Storm Warning Center observed that Tropical depression Hagupit was centered in close proximity to latitude 29.8 degrees north and longitude 120.3 degrees east, about 104 nautical miles southwest of Shanghai, China. Hagupit was going to the north with greatest sustained winds lowering to 30 knots (35 mph/56 kph).

Hagupit is transferring inland above eastern China and the Joint Hurricane Warning Heart forecasts that it will reemerge into the Yellow Sea on Aug. 5, but adverse circumstances will lead to Hagupit’s dissipation.

The AIRS instrument is a person of 6 devices traveling on board NASA’s Aqua satellite, introduced on Might 4, 2002.

For a lot more than five many years, NASA has used the vantage point of room to have an understanding of and take a look at our dwelling world, boost life and safeguard our long run. NASA provides collectively technological know-how, science, and exceptional worldwide Earth observations to give societal gains and reinforce our country. Advancing awareness of our property world contributes specifically to America’s management in place and scientific exploration.
