NASA-NOAA's Suomi NPP satellite catches Tropical Depression Ampil over Eastern China

July 23, 2018

NASA-NOAA's Suomi NPP satellite passed over the Northwestern Pacific Ocean and captured a visible image of Tropical Depression Ampil moving over land in eastern China.

On July 23 at 12:54 a.m. EDT (0454 UTC) the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA's Suomi NPP satellite captured visible image of Ampil over Shandong, an eastern Chinese province on the Yellow Sea. The VIIRS image showed Ampil's center was located over land. The VIIRS image showed the most powerful band of thunderstorms wrapping into the low-level center from the east and the Yellow Sea.

On July 2 at 11 a.m. EDT (1500 UTC) Ampil's center was located near 37.1 degrees north latitude and 118.2 degrees east longitude. That's approximately 407 nautical miles west on Inchon, South Korea. Ampil was moving to the north at 17 mph (15 knots/27.7 kph). Maximum sustained winds were near 28.7 mph (25 mph/46.3 kph).

The Joint Typhoon Warning Center or JTWC forecast said Ampil is moving northwest over eastern China and will briefly move back in over waters of the Bohai Bay. The storm is then forecast to track back over land and dissipate in the next couple of days.

#524 The Human Network
What does a network of humans look like and how does it work? How does information spread? How do decisions and opinions spread? What gets distorted as it moves through the network and why? This week we dig into the ins and outs of human networks with Matthew Jackson, Professor of Economics at Stanford University and author of the book "The Human Network: How Your Social Position Determines Your Power, Beliefs, and Behaviours".
