Earth Changes
Unusual noctilucent clouds can be seen in the night sky over Moscow. This was announced on Wednesday TASS director of the Hydrometeorological Center of Russia Roman Vilfand.
He noted that this phenomenon is a beautiful decoration in Summer sky. Such clouds can be observed on 4 and 5 July in the clear sky at night.
"These clouds are visible at night, they are often also called nocturnal clouds They are silvery and beautifully lit at night. When the sun sets, its rays penetrate deep into the atmosphere, penetrating it with light." - Vilfand said.
According to him, the noctilucent clouds are a cluster of molecules of water vapor. "These clouds are very high, at a distance of about 100 km from the surface of the Earth. To predict their occurrence can not be because we do not understand their nature. They appear in the summer, and the nature of these clouds is not fully known..." said Vilfand.
Karen Butler of Nanaimo snapped a few pictures of bright colours dancing across the clouds a few days ago, the result of a circumhorizon arc.
A circumhorizon arc is a halo of sorts, and it appears when the sun is very high in the sky - higher than 58°. It's typically oriented parallel to the horizon. Often it's only visible in fragments when cirrus clouds aloft are lit with a rainbow of colours. The colours are the result of sunlight passing through the ice crystals that make up the cirrus cloud. The crystals themselves act like a prism, essentially splitting the sunlight into the spectrum of colours.
Reported in the 20200 block of Highway 212, near South Wiese Road, the sinkhole is 20 feet wide by 4 feet deep, transportation officials said Sunday.
According to the Sunrise Water Authority, a water main broke, emptying a 1-million-gallon reservoir. Water service was restored to the reservoir.
Sunrise Water Authority urged customers who lost water pressure or service to boil any water that was used for drinking purposes only. All other uses, such as showers, baths, and watering, are safe, the bureau said. The boil water advisory was lifted Monday evening.
On-site witnesses said that a funnel-shaped rotating waterspout suddenly appeared after the sky was covered by black clouds. The whole process lasted for over ten minutes, Global Times reported.
According to a local meteorologist, the waterspout in Dangxiong was actually a "land tornado", which is a strong wind whirlpool created when the base of the thundercloud reaches to the ground. It usually happens in summer afternoons or dusks when there are thunderstorms.
It is the first time a land tornado has been spotted in Tibet since the autonomous region started meteorological observation in 1961.
The large hole, at the junction of the major commuter route and Beech Street, formed this morning and began at three metres deep and six metres wide.
Throughout the day the hole has continued to grow , as an investigation involving bodies including the council, gas experts and United Utilities gets under way to determine the cause.
John Brown, manager at the Devonshire House Hotel, which is close to the site of the sinkhole, said staff have been told it could be three to four weeks before it is fully repaired.
The quake appears to be the largest to hit Montana since a slightly weaker M5.6 struck outside of Dillon a dozen years ago. By comparison, the state's largest quake which struck the West Yellowstone region 58-years ago was 7.2 magnitude.
