August 12, 2010 - Tropical Storm Dianmu (05W) approaching Korea
Tweet
Tropical Storm Dianmu blew over the East China Sea in early August 2010, traveling slowly toward the Korean Peninsula. On August 10, 2010, the U.S. Navy’s Joint Typhoon Warning Center (JTWC) reported that Dianmu had winds of 55 knots (100 kilometers per hour) with gusts up to 70 knots (130 kilometers per hour). JTWC stated that the storm was roughly 270 nautical miles (500 kilometers) south-southwest of Seoul.
The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this natural-color image on August 10. The storm, which sports a distinct eye, stretches primarily north-south, sending spiral clouds hundreds of kilometers southward over the East China Sea. Storm clouds skirt China’s eastern coast.
On August 11 at 15:00 UTC (11:00 AM) Dianmu was loated 500 miles west-southwest of Misawa, Japan and moving west-northeast near 20 miles per hour. It quickly crossed South Korea, generating 15-foot high waves in the Sea of Japan. By 16:29 UTC (12:29 p.m. EDT) Dianmu was reported to have elongated, with most of the convection to the eastern part of the storm.
Dianmu is transitioning into an extra-tropical storm as it encounters increasing vertical wind shear and cooler sea surface temperatures. Those are two factors that weaken a tropical cyclone. Dianmu is expected to make landfall over north Honshu, Japan on August 12.
