Clouds of Arrows on Titan

Titan, Saturn's largest moon, has a mysterious structure dart-shaped area of five times the island of Java in its atmosphere. Scientists from the University of California, Los Angeles, claims can explain these formations. Cassini spacecraft, orbiting Saturn, discovered an arrow-shaped clouds on Titan September 2010 at the equator. Length of an enormous cloud baffled researchers about the process of formation. Planetary scientist uses a global air circulation model to explain the phenomenon of the weather satellite. Atmospheric waves that create a giant scratch on the top layer of the planet. "This is a natural atmospheric waves like a resonance on a glass of wine," said research fellow planetary science, aerospace, marine and University of California, Jonathan Mitchell. Methane clouds in Titan's atmosphere act like a ringing a large bell. The resulting wave clouds are spread to other locations so it would affect the vibrations of all the clouds in the atmosphere. Some special forms, like an arrow, is the accumulation of waves from all directions to suppress steam methane. High pressure in the atmosphere resulting in increased rainfall. Just below the arrow-shaped clouds, rainfall can reach 20 times higher than normal conditions. This mysterious cloud which produces erosion carved Titan mainland. "Our next job is to predict the formation of clouds and weather patterns using the same model," said Mitchell. Previous research shows Titan has a tropical weather across parts. Titan also has a structure similar to the Earth's atmosphere. Therefore, studying the atmospheric processes on Titan would enrich human knowledge about the formation of weather patterns on Earth. *** [SPACE | ANTON WILLIAM | KORAN TEMPO 3623]
