How is the stratosphere different from the other layers?
Unlike the troposphere, the stratosphere actually gets warmer the higher you go! That trend of rising temperatures with altitude means that air in the stratosphere lacks the turbulence and updrafts of the troposphere beneath.
What is the difference in temperature between the top of the stratosphere and the top of the troposphere?
Heat is produced in the process of the formation of Ozone and this heat is responsible for temperature increases from an average -60°F (-51°C) at tropopause to a maximum of about 5°F (-15°C) at the top of the stratosphere. This increase in temperature with height means warmer air is located above cooler air.
Which portion of the stratosphere is more warmer the upper or lower portion and why?
Stroao- means layer or spread out. The stratosphere is the second laryer of the atmosphere and contains the ozone layer. The lower stratosphere is cold – supprisingly the upper stratosphere is warmer. It is the layer of the atmosphere that protects the EArth’s surface from being hit by most meteoroids.
Why is the top of the stratosphere hot?
The rapid photolysis and reformation of ozone heat the stratosphere, resulting in a temperature inversion. Within the stratosphere temperatures increase with altitude (see temperature inversion); the top of the stratosphere has a temperature of about 270 K (−3°C or 26.6°F).
What gases make up the stratosphere?
Temperatures in the stratosphere increase with altitude. A high concentration of ozone, a molecule composed of three atoms of oxygen, makes up the ozone layer of the stratosphere.
What is the main reason that the stratosphere is warmer than we expect?
The upper stratosphere is warmer than the lower stratosphere because ozone gas absorbs and scatters the Suns ultraviolet rays.
Which is the lower boundary of the stratosphere?
The lower boundary of the stratosphere can be as high as 20 km (12 miles or 65,000 feet) near the equator and as low as 7 km (4 miles or 23,000 feet) at the poles in winter. The lower boundary of the stratosphere is called the tropopause; the upper boundary is called the stratopause.
Why do planes fly in the lower stratosphere?
Commercial jet aircraft fly in the lower stratosphere to avoid the turbulence which is common in the troposphere below. The stratosphere is very dry; air there contains little water vapor. Because of this, few clouds are found in this layer; almost all clouds occur in the lower, more humid troposphere.
How tall is the mesosphere above the stratosphere?
Above the stratosphere is the mesosphere. It extends upward to a height of about 85 km (53 miles) above our planet. Most meteors burn up in the mesosphere. Unlike the stratosphere, temperatures once again grow colder as you rise up through the mesosphere.
Which is the second layer of the atmosphere?
Credit: Randy Russell, UCAR. The stratosphere is a layer of Earth’s atmosphere. It is the second layer of the atmosphere as you go upward. The troposphere, the lowest layer, is right below the stratosphere. The next higher layer above the stratosphere is the mesosphere.
