Australian naturalphenomenon gloriamatutina 只有澳洲才有的奇景--雲浪
In the Gulf of Carpentaria, northern Australia, between September and November, an extraordinary phenomenon of unparalleled beauty: the morning glory cloud.
If the weather situation is calm, every morning when the sun rises, a wave-shaped cloud, 1.6 to 3.2 kilometres high and 600 to 1,000 kilometres, ie, that it fills the horizon, moving at a speed of 40 kilometres per hour.
Sometimes there are several waves and always aligned from east to west. The cause is a clash of air masses of different temperatures.
In the early hours of the morning, a mass of warm, moist air, from the sea, slips over the cooler air that is in the upper layers. In late 2006, scientists from several countries traveled to study the phenomenon, which occurs in many places in the world. It has been observed on the Catalan coast of Spain.
The clash of air masses takes place in Spain, but does not result in the formation of this peculiar cloud. This phenomenon is unique to Australia.
Since 1989, every spring, when the phenomenon occurs, hang gliders and paragliders cloud surf waves like waves in an ocean. You have to be careful because the waves produce strong turbulence and can be dangerous. They fly in zigzag patterns and can travel up to 480 kilometres
