Tropical Cyclone Son-Tinh makes landfall and NASA examines its trail of rainfall


TropicalCyclone Son-Tinh made landfall in Vietnam and left a trail of heavy rainfall in its wake. NASA’s Global Precipitation Measurement objective or GPM core satellite offered a price quote of that soaked trail through the Gulf of Tonkin.

Tropical storm Son-Tinh struck Hainan Island, China and was headed towards northern Vietnam when the GPM core observatory satellite passed over the Gulf of Tonkin, South China Sea on July 17, 2018 at 6: 49 p.m. EDT (2249 UTC). Data gathered by GPM exposed that heavy rainfall was currently happening in the Gulf of Tonkin well to the west of hurricane Son-Tinh’s center of flow.

GPM is a joint objective in between NASA and the Japan Aerospace Exploration Agency, JAXA. GPM’s Microwave Imager (GMI) and Dual-FrequencyPrecipitation Radar (DPR) information revealed the areas of heavy rainfall in storms in the western Gulf ofTonkin GPM’s radar (DPR Ku Band) scans of that rainy location exposed that rainfall was dropping at a rate of well over 97 mm (3.8 inches) per hour.

AtNASA’s Goddard Space Flight Center in Greenbelt, Maryland a simulated 3-D observation of rainfall in the Gulf of Tonkin was produced with information gathered by GPM’s radar (DPR Ku Band). The 3-D view revealed heavy rainstorms were returning strong radar echoes to the GPM satellite. Storm tops in the most effective storms were discovered by DPR to reach heights of about 16 km (9.9 miles).

At 5 p.m. EDT (2100 UTC) on July 18, Tropical Storm Son-Tinh made landfall in northern Vietnam and the Joint Typhoon Warning Center released their last caution on the system. At that time, it had optimal continual winds near 45 knots (52 miles per hour/83 kph). It lay near 19.0 degrees north latitude and 105.5 degrees east longitude, about 122 nautical miles south of Hanoi,Vietnam Son-Tinh was relocating to the west at 12 knots (138 miles per hour/222 kph).

Son-Tinh brought heavy rainfall over northern Vietnam and Laos and is anticipated to dissipate quickly.
