Why is the stratosphere warmer than the upper troposphere quizlet?

Why is the stratosphere warmer than the upper troposphere quizlet?

Why is the temperature in the upper stratosphere higher than the temperature in the lower stratosphere? Unlike the troposphere, the highest part of the stratosphere is warmer than lower levels. The upper stratosphere is warmer than the lower stratosphere because ozone gas absorbs and scatters the Suns ultraviolet rays.

Why does the stratosphere warm up?

Every year in winter, strong westerly winds circle around the pole high up in the stratosphere. The cold air then descends very rapidly in the polar vortex and this causes the temperature in the stratosphere to rise very rapidly, as much as 50°C over only a few days; hence the term sudden stratospheric warming.

Is the upper stratosphere cooler than the lower?

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.

What would a warm air mass over the ocean most likely cause?

What would a warm air mass over the ocean most likely cause? Winds blowing inland from oceans tend to have greater moisture than winds blowing over land.

Can you breathe in the stratosphere?

The stratosphere is not a good place to be. First, the ozone in the stratosphere, which protects us from biologically destructive solar ultraviolet light, exists at such high levels that the air itself is toxic. Second, even this toxic air is much too thin for normal breathing.

What are 3 facts about the stratosphere?

Four Facts About the Stratosphere

• Stratosphere Facts and Stratosphere Definition. The stratosphere altitude is still high, though.
• Temperature Increases With Height.
• The Stratosphere Is Where Jets Like to Fly.
• The Ozone Layer Is in the Stratosphere.
• Swans, Cranes and Vultures Can Fly in the Stratosphere.

Why do jet planes fly in 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.

What are the 2 major causes for moving air masses in North America?

One major influence of air mass movement is the upper level winds such as the upper level winds associated with the jet stream. The jet stream wind is often referred to as a steering wind. The troughs and ridges of the jet stream will help transport cold air toward lower latitudes and warm air toward high latitudes.

What air mass has the most moisture?

maritime air masses
Air masses that form over the ocean, called maritime air masses, are more humid than those that form over land, called continental air masses. The second part of the name describes the temperature of the air mass, which depends on the latitude where it formed.

What 2 things can fly in the stratosphere?

Air is roughly a thousand times thinner at the top of the stratosphere than it is at sea level. Because of this, jet aircraft and weather balloons reach their maximum operational altitudes within the stratosphere.

Can you breathe at 35000 feet?

Partial pressures. You can breath at 35,000 ft without a pressured suit, but go much higher and you can’t. At sea level, you have 760 mmHg of air pressure. At 35,000 ft, air pressure is 179 mmHg [1], so if you breath 100% pure oxygen, you’re getting the same amount of oxygen you’d get at sea level.

Is the stratosphere hot or cold?

In the stratosphere, temperature increases with altitude. The stratosphere contains the ozone layer, which protects the planet from the Sun’s harmful UV. The higher layers contain few gas molecules and are very cold.

Why is the stratosphere warmer than the troposphere?

Ozone in the stratosphere heats the air up when it absorbed sunlight. It warms the stratosphere up but not quite enough to make it warmer than the air nearest to the surface.

Is the troposphere warming faster than models predict?

Overall, the study suggests that while tropospheric warming has not accelerated to the extent that models have predicted in recent years, there’s little evidence that it has slowed down. Much of our historical temperature data comes from weather stations, ships, and buoys on the Earth’s surface.

How is the temperature of the troposphere measured?

However, the bands measured by the satellite instruments cannot easily provide the temperature of a specific layer of the atmosphere.

How big are the bands in the troposphere?

Researchers have identified particular sets of bands that correspond to the temperature of the lower troposphere (TLT) spanning roughly 0 to 10 km, the middle troposphere (TMT) spanning around 0 to 20 km and the lower stratosphere (TLS) spanning 10 to 30 km. Unfortunately, these bands tend to overlap a bit.
