How can a gang kungli pass over the sea without any break?

ByAndrea Westmoreland

Gongkangli living in the tropical ocean has been known for its ability to fly high and continue to fly for several weeks without leaving the ground etc on the way. However, as a result of research, I have learned that I have the ability to fly for over 2 months by using the surrounding environment well.

this isFrench National Center for Scientific ResearchHenri Weimerskirch of France, the University of Rochelle in France, as well as researchers from the UK, Canada and Germany, and was announced in "Science" issued on July 1, 2016.

Weimerskirch Mr. and Mr. Weimerskirch attached a tag with a sensor that counts the number of times GPS, pulse rate, flapping on about 50 young gangsters in Yellowopa island of Mozambique Strait, which is a breeding ground of Gunkandoli, fluttering while flight I read from the data as to whether it is or whether it is gliding and examined how much energy is consumed for the movement.

Yupau Island is an uninhabited island of French territory located in the Mozambique Strait between Mozambique and Madagascar.


From the tags attached to the gun kandali, after they jumped out of the island of Europa, we found that they are crossing the Indian Ocean to Indonesia via the tropical cyclone region near the equator called "equatorial windless" It was. At this time, Gunkandri used a trade wind blowing the Indian Ocean.

Incidentally, there are individuals that this journey is "the first trip from the birthplace", but still the flight distance exceeds several thousand kilometers. The journey extends over two months, but during that time, sometimes you can not put your feet on the ground at all.

This trip is realized by using a pattern called "roller coaster flight" by Gunkandri. "Roller coaster flight" means using convection under the cumulus cloud to raise the altitude without slipping in the air flow without flapping. According to the data obtained, there are times when the movement of gunkandri may become sluggish in a short cycle during this ascending flight, and it is believed to be sleeping for several minutes each.

Once you reach the "bottom" of the cumulus clouds (altitude 600 m - 700 m), glide over several kilometers from there. In an area where the clouds are small, we will glide over long distances by using the ascending air current inside the cumulus to raise the altitude to 3000 m - 4000 m and then glide.

However, as it is said that "the temperature drops by 0.6 degrees every time the temperature increases by 100 m," this altitude temperature is as low as 18 to 24 degrees compared to the altitude of 0 m, so the feathers worn by the gun kun crust will have sufficient temperature It should not be able to adapt to.

...... So, "I understand that Gunkandri glides on energy consumption by suppressing energy consumption", but on the other hand, "Gunkandri is asleep during flight" "Inside cumulus "It seems that the survey has turned out to be a new investigation in which new questions are found one after another that" it has the power to choose a flight route that avoids the cyclone (tropical cyclone) ".

An excerpt from the "INDEPENDENCE DAYS" that follows the movements of this gun kun crust has been released.
