On Aug. 6 at 20:55 UTC (4:55 p.m. EDT) NASA's Aqua satellite flew over Mangkhut as it tracked west-northwest through the Gulf of Tonkin on its way to a landfall. Aqua's Atmospheric Infrared Sounder or AIRS instrument captured infrared data that showed that cloud top temperatures of some thunderstorms around Mangkhut's center were as cold as 210 kelvin/-81F/-63C indicating powerful storms with the potential for heavy rainfall.
This Aug. 6 infrared image from AIRS on NASA's Aqua satellite showed that cloud top temperatures in Mangkhut are as cold as 210 kelvin/-81F/-63Ct (purple) indicating powerful storms.
The AIRS data also measures temperatures over land, and in the same image where it captured Tropical Storm Mangkhut, the data showed some of the surface temperatures in eastern central China appeared warmer than 300 kelvin/80F/26.8C at 1841 UTC on Aug. 6 or 2:41 a.m. China local time. Those are warm overnight temperatures!
Early on Aug. 7, the Joint Typhoon Warning Center noted that "Animated infrared satellite imagery shows the deep convective bands associated with the system have collapsed as they began to interact with the topography of Vietnam." A Tropical Storm Warning remains in effect for Aug. 7, according to the Vietnam National Centre for Hydro-Meteorological Forecasting.
At 1500 UTC (11 a.m. EDT) on Aug. 7, Mangkhut's center was very close to landfall. Maximum sustained winds were near 35 knots, making it a minimal tropical storm. Mangkhut was about 92 nautical miles/106 miles/170 km south of Hanoi, Vietnam, near 19.8 north latitude and 105.8 east longitude. It was moving to the west-northwest at 13 knots/15 mph/24 kph.
After Mangkhut makes landfall about 65 miles south of Hanoi, the storm is expected to dissipate within 24 hours.

Scientists from the Theory Department of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science (CFEL) in Hamburg have shown through theoretical calculations and computer simulations that the force between electrons and lattice distortions in an atomically thin two-dimensional superconductor can be controlled with virtual photons. This could aid the development of new superconductors for energy-saving devices and many other technical applications.
The vacuum is not empty. It may sound like magic to laypeople but it has occupied physicists since the birth of quantum mechanics.
