Sep. 06, 2019 – GPM Satellite Finds Heavy Rainfall on Northern Side of Typhoon Lingling
The Global Precipitation Measurement mission or GPM core satellite analyzed the rainfall rates happening within Typhoon Lingling and found the heaviest precipitation on its northern side.
The GPM core satellite passed over Typhoon Lingling in the South China Sea on Sept. 6 at 2:16 a.m. EDT (0616 UTC). GPM found the heaviest rainfall at a rate greater than 1.6 inches (40 mm) per hour, falling northwest and northeast of center in fragmented thunderstorms. The heaviest rain areas were surrounded by less heavy rain, falling at a rate of 20 mm (about 0.8 inch) per hour. Lighter rainfall rates around those areas was between 0.2 and 0.4 inches (5 and 10 mm) per hour. NASA and the Japan Aerospace Exploration Agency, JAXA.
NASA researches tropical cyclones and provides data to international partners to use in their forecasting.
At 11 a.m. EDT (1500 UTC), Typhoon Lingling had maximum sustained winds near 100 knots (115 mph/185 kph). It was centered near 31.2 degrees north latitude and 125.0 degrees east longitude, about 293 nautical miles south-southwest of Kunsan Air Base, South Korea.
The Joint Typhoon Warning Center forecast calls for Lingling to move north through the Gulf of Tonkin. The Gulf of Tonkin is located off the coast of northern Vietnam and southern China. It is considered a northern arm of the South China Sea. Lingling is forecast to make landfall near Pyongyang, North Korea.
Sep. 05, 2019 – NASA-NOAA Satellite Sees Typhoon Lingling’s Eye Near Miyako
Typhoon Lingling’s eye was passing near the island of Miyako when NASA-NOAA’s Suomi NPP satellite passed overhead on Sept. 5. Miyako is one of the Ryukyu Islands located in the Northwestern Pacific Ocean.
The Ryukyu Islands are a chain of Japanese islands that stretch southwest from Kyushu to Taiwan.
On Sept. 5 at 1:24 a.m. EDT (0524 UTC), the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard Suomi NPP captured the visible image that showed the southwestern eyewall of Typhoon Lingling over the island of Miyako. In the image, Okinawa was being affected by the northeastern quadrant of the storm, and the islands of Senkaku and Yaeyama were experiencing winds and rain from the southwestern quadrant.
At 11 a.m. EDT (1500 UTC) on Sept. 5, the Joint Typhoon Warning Center (JTWC) noted that Lingling had maximum sustained winds near 115 knots. It was centered near 25.7 degrees north latitude and 125.3 degrees east longitude, about 143 miles west-southwest of Kadena Air Base, Okinawa Island, Japan. It was moving to the north.
Lingling is moving north and the JTWC forecasters noted it has reached peak intensity. The system is expected to weaken on approach to the Korean peninsula, but still be at typhoon strength at landfall near Pyongyang, North Korea.
Sep. 04, 2019 – NASA Catches the Eye of Typhoon Lingling
Typhoon Lingling continues to strengthen in the Northwestern Pacific Ocean and NASA’s Terra satellite imagery revealed the eye is now visible.
On Sept. 4 at 1:20 a.m. EDT (0520 UTC) the Moderate Imaging Spectroradiometer or MODIS instrument that flies aboard NASA’s Terra satellite showed powerful thunderstorms circling Typhoon Lingling’s visible 15 nautical-mile wide eye. The Joint Typhoon Warning Center (JTWC) noted, “Animated enhanced infrared satellite imagery depicts tightly-curved banding wrapping into a ragged eye.” In addition, microwave satellite imagery showed a well-defined microwave eye feature.
At 11 a.m. EDT (1500 UTC), the Joint Typhoon Warning Center or JTWC said that Typhoon Lingling, known locally in the Philippines as Liwayway, had moved away from the Philippines enough that warnings have been dropped.
Lingling was located near 23.0 degrees north latitude and 125.4 degrees east longitude. That is 247 nautical miles southwest of Kadena Air Base, Okinawa, Japan. Lingling was moving to the north-northeast and maximum sustained winds had increased to near 80 knots (75 mph/120.3 kph).
JTWC forecasters said that Lingling is moving north and is expected to intensify to 105 knots (121 mph/194 kph) upon passing between Taiwan and Japan.
Sep. 03, 2019 – NASA Infrared Eye Analyzes Typhoon Lingling
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.
At 11 a.m. EDT (1500 UTC), the Joint Typhoon Warning Center or JTWC said that Typhoon Lingling, known locally in the Philippines as Liwayway was located near 21.4 degrees north latitude and 124.2 degrees east longitude. That is 364 nautical miles southwest of Kadena Air Base, Okinawa, Japan. Lingling was moving to the north and had maximum sustained winds near 65 knots (75 mph/120.3 kph).
JTWC forecasters said that Lingling is moving north and is expected to intensify to 100 knots (115 mph/185 kph) upon passing east of Taiwan. The system will then weaken on approach to the Korean peninsula, but still be at typhoon strength.
