1. Aurora ,nike tn chaussures

no doubt, Aurora comes as one of Earth's most beautiful natural phenomena. When the sun release of high-energy plasma particles stream, called the solar wind, from 300 to 1200 kilometers per second speed, reach the earth through the solar system over the interaction with the Earth's magnetic field, a number of particles drawn into the Earth's atmosphere, the ionosphere (from the Earth's surface is about 60-600 km) along the direction of magnetic field lines forming a plasma as ethereal as clouds, because of this particle collisions in the ionosphere excited by different excitation levels rise colorful glory. The more than beauty, in North and South poles (Earth's magnetic field the strongest regional), they named Aurora.

2.

super super thunderstorm thunderstorm is a kind of rotation to the center by the constantly rising air in the cyclone formed by thunderstorms. Four types of thunderstorms in the known, the super-size and thunderstorms are most harmful kind. They are often isolated thunder cloud,abercrombie clothing, sometimes divided into two parts, lasting a few hours or so. Thunderstorms bring hail, heavy rain and windy weather,cheap nfl jerseys, and sometimes even lead to a tornado.

3. rotating rotating flame flame

called strange fire, fire whirlwind,ralph lauren pas cher, is when the fire occurs, the air temperature and thermal gradient to meet certain conditions to form a vertical flame whirlpool, whirlwind straight into the sky, a rare phenomenon. Rotating fire in bush fires and more. Flame height ranging from 30 to 200 feet, and limited duration, generally only a few minutes, but if the wind strength can be sustained much longer.

4.

milky milky cloud cloud image and a better name, \Because of decreased flow in the cooler temperatures and increased air flow in the air temperature warmer and meet to form.
it can extend hundreds of miles over the direction of each tile can be kept static sheet of clouds 10 to 15 minutes. Beauty is a price, it often precedes the emergence of the future may have a storm or other extreme weather events.

5.

when the water red tide algae in the estuary, the mouth of the rapid propagation of sudden accumulation, which makes the whole area into a blood red ocean or beach phenomenon, called red tide, sometimes called red tide, which is a definition of the concept of history, not all red tides are present when the water red, according to the number of cause of red tide organisms, the species, sometimes appear yellow, green and brown and so on.
While some algae are relatively harmless,cheap nike shoes, but there will be a lethal toxin, resulting in fish, seabirds and marine mammals died. Today, human emissions of water eutrophication has become the main cause of this phenomenon.

6. Cone of Cold Cone of Cold group group

strange sights in the world of nature, it is mainly distributed in the high altitude, snow mountain, Cone of Cold sizes, ranging from small to several centimeters ranging from 5 meters. At first, the sunlight on the snow, forming many irregular concave, and after a period of time, concave to accept the sun, more than the thrill of climbing around,christian louboutin sale, absorbing the greater the degree of sublimation, the final formation of deep grooves, Cone of Cold stand between them.

7. will move the stone

desert in Death Valley, so a strange phenomenon: There are many giant boulders form, each of which weigh seven hundred pounds or more, look here are their own campaigns, and these rocks in the sliding process,herve leger sale, created in its wake profound \Gravitational theory simply does not work seems, scientists have yet to make a unified interpretation, it was considered to be the local strong winds and rotation caused by the joint action of dust.

8. ice ring

when the water swirl in a certain diameter size of a circular rotation, making the water ice and floating impurities uniformly distributed in the whirlpool, then we see the formation of to perfect this mysterious ice circle. Currently found in the largest diameter of the more than 500 feet of ice, in addition to people in different places and times the diameter of the ice found in different circles.

9. gravity wave gravity wave cloud cloud

rolling texture is derived from the movement of air in the vertical plane, such as updraft or thunderstorm formation.
updraft gas vortex of air changes, cloud characteristics of the fluid also changed, when the frequent occurrence of this role, the different changes in a gradient, forming visible clouds of gravity waves oscillation.
