Atmosphere of Earth that gas. The stratosphere defines a layer in which temperatures rise with increasing altitude. This rise in temperature is caused by the absorption of ultraviolet radiation (UV) radiation from the Sun by the ozone layer, which restricts turbulence and mixing. Although the temperature may be at the tropopause, the top of the stratosphere is much warmer, and may be near 0 °C. The stratospheric temperature profile creates very stable atmospheric conditions, so the stratosphere lacks the weather-producing air turbulence that is so prevalent in the troposphere. Consequently, the stratosphere is almost completely free of clouds and other forms of weather.
High Roller (Stratosphere) High Roller (Stratosphere) The High Roller (also known as the Let it Ride High Roller), was a steel roller coaster constructed on top of a building over the Las Vegas Strip. It was the highest roller coaster in the world when compared to the surrounding terrain. It was located on top of the Stratosphere Tower, Las Vegas, Nevada, which is the tallest free-standing observation tower in the United States. The coaster was manufactured by S&MC GmbH Structures and Machines. The ride opened on April 29, 1996, in a special VIP gala opening, one day before the ride and casino opened
