Aug. 24, 2018 – NASA Tracks Tropical Storm Soulik into the Sea of Japan
NASA’s Aqua satellite flew over Tropical Storm Soulik after it moved into the Sea of Japan and saw that wind shear was adversely affecting the storm.

On Aug. 24 at 12:40 a.m. EDT (0430 UTC) the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard Aqua captured a visible light image of Soulik after it moved off the Korean Peninsula. The image showed the bulk of clouds were being pushed north of the low level center, as the southern quadrant was almost devoid of clouds, except for a small ring around the center.
At 11 a.m. EDT (1500 UTC) on Aug. 24, the center of Tropical Storm Soulik was located near 41.0 degrees north latitude and 133.0 degrees east longitude. That’s about 349 nautical miles northeast of Yongsan. The Yongsan Garrison located in the Yongsan District of Seoul, South Korea.
Soulik is speeding to the northeast at 36 knots (41 mph/67 kph) and maximum sustained winds are near 35 knots (40 mph/62 kph) with higher gusts.
The Joint Typhoon Warning Center or JTWC expects Soulik to move rapidly across the Sea of Japan and will become extra-tropical before reaching Hokkaido.

Aug. 24, 2018 – NASA’s Aqua Satellite Finds an Extra-Tropical Cyclone Cimaron
Cimaron has crossed the big island of Japan and became an extra-tropical cyclone. NASA’s Aqua satellite looked at Cimaron in infrared light and saw cloud tops were warming as the elongated storm weakened.
NASA’s Aqua satellite observed Cimaron in infrared light that revealed cloud top temperatures on Aug. 24 at 12:40 a.m. EDT (4:40 UTC) were coldest (yellow) and as cold as minus 50 degrees Fahrenheit (minus 45.5 degrees Celsius) in west central Japan. Credit: NASA/NRL
On Aug. 24 at 12:40 a.m. EDT (4:40 UTC) the MODIS instrument or Moderate Resolution Imaging Spectroradiometer aboard Aqua saw cloud tops dropped in the atmosphere and warmed, indicating the uplift of air in the storm was weakening.
Infrared data provided cloud top temperatures. The coldest clouds were the strongest storms. NASA’s Aqua satellite found two areas where cloud top temperatures were coldest and as cold as minus 50 degrees Fahrenheit (minus 45.5 degrees Celsius). One larger area was located in west central Japan and moving into the Sea of Japan. The second smaller area was located over east central Japan.
On Aug. 24 at 5 a.m. EDT (0900 UTC) the Joint Typhoon Warning Center issued the final bulletin on Extratropical Storm Cimaron. The storm had crossed central Japan and was emerging into the Sea of Japan. It was centered near 40.8 degrees north latitude and 137.7 degrees east longitude, about 161 miles west of Misawa, Japan. Cimaron was moving to the north-northeast and had maximum sustained winds near 45 knots (52 mph/83 kph).
Cimaron was moving northeast and has become extra-tropical and asymmetric. Computer forecast models show that Soulik and Cimaron would remain two separate systems. Soulik is located to the southwest of Cimaron
