Super Typhoon Haishen approaching western Japan and Korean Peninsula (Details)

 Super Typhoon Haishen approaching western Japan and Korean Peninsula (Details).

Haishen has intensified into 2020’s first super typhoon as it tracks towards Japan and South Korea.

The Joint Typhoon Warning Center (JTWC) defines a super typhoon as one that reaches maximum sustained one-minute surface winds of at least 150 mph (241.4 km/h), which is equivalent to a Category 4 or 5 hurricane on the Saffir-Simpson scale in the Atlantic basin.

In its latest statement, JTWC says Haishen’s maximum sustained wind gusts are 250 km/h, with gusts reaching as high as 306 km/h -- equivalent to a Category 4 hurricane. It is forecast to strengthen Friday night and obtain wind speeds that are equivalent to a Category 5 hurricane.

Haishen could hit Japan Sunday as the equivalent of a Category 3 storm before tracking into South Korea as a Category 2 storm by Monday morning. There is increasing uncertainty in the exact track over South Korea, though one particular model indicates the storm will move further west than others have shown.

Sayaka Mori, a meteorologist for NHK World, says that Haishen would break the record for the most landfalling storms in a single season if it strikes South Korea, as reported by The Washington Post.

Record levels of rainfall, severe flooding and mudslides are potential impacts from this storm. Officials warn that Haishen will cause significant damage even if the storm does not make landfall.

Haishen and Maysak

Several regions in South Korea and Japan are recovering from Typhoon Maysak after it made landfall in South Korea on Thursday. Intense wind gusts and heavy rains resulted in at least two fatalities in the city of Busan.

Four tropical disturbances, depression this week

 Four tropical disturbances, depression this week. We’re almost to the peak of hurricane season, and right on cue, we’re watching four new disturbances in the Atlantic Basin. Two of which have a high chance of becoming a depression this week. The front-runner is INVEST-92L, which is producing a disorganized cluster of storms this morning. 92L is expected to push off to the west-northwest in the central Atlantic over the next several days, where conditions will be favorable for it to become a tropical depression or storm. The  National Hurricane Center gives this disturbance a high 90% chance of development over the next 5 days. Behind 92L, a vigorous tropical wave is forecast to push off the west African Coast today. A tropical depression is likely to form by the middle of next week as it pushes westward across the eastern tropical Atlantic. Right now, the National Hurricane Center is giving it a high 80% chance of development over the next 5 days. Computer models are bul...

Flying-V airplane maiden flight, day bring travelers in its wings

 Flying-V airplane maiden flight, day bring travelers in its wings. Researchers have actually carried out a successful maiden flight of the  Flying-V , a futuristic and fuel effective airplane that might one day bring travelers in its wings. The Flying-V’s special style puts the  passenger cabin , the freight hold and the fuel tanks in the wings, and professionals hope that the aircraft’s aerodynamic shape will cut fuel usage by 20% compared to today’s airplanes. Experts evaluated a 22.5 kg and 3-meter scale design of the futuristic airplane, established by scientists at Delft University of Technology in the Netherlands and partner Dutch airline company KLM, to take the extremely prepared for airplane along its next developmental actions. A group of scientists and engineers evaluated the airplane at a secured airbase in Germany, where they dealt with an Airbus group to check departures, maneuvers and methods, and landing. “One of our worries was that the aircraft mi...
