What runs along the troposphere?
A river of air called the jet stream runs along the troposphere just near the top. The troposphere starts at ground level and rises 11 km up which is equivalent to 7 miles or 36,000ft. Most of the clouds are found in the troposphere layer.
What’s on top of the troposphere?
The layer immediately above the troposphere is called the stratosphere. The boundary between the troposphere and the stratosphere is called the “tropopause”.
What runs along the top of the troposphere and the bottom of the stratosphere?
When the thunderstorm reaches the top of the troposphere, it runs into the bottom of the stratosphere which is a very stable layer. Cruising altitude in a passenger jet is usually between 30,000 and 40,000, near or just above the top of the troposphere, and at the bottom of the stratosphere.
What attaches to the jet stream?
Jet streams form when warm air masses meet cold air masses in the atmosphere. So when Earth’s warmer air masses meet cooler air masses, the warmer air rises up higher in the atmosphere while cooler air sinks down to replace the warm air. This movement creates an air current, or wind.
What are two characteristics of the upper troposphere?
Characteristics of troposphere
- it is the first atmospheric layer closet to Earth’s surface.
- the troposphere is the region where weather occurs.
- the temperature of troposphere decreases with an increase in height.
- the troposphere makes up approximately 75% of Earth’s atmosphere by mass.
What determines the height of the troposphere?
the lowest temperature level determine the height of the Tropopause Layer. The tropopause occurs at approximately 20,000 feet over the poles and at approximately 60,000 feet above the equator.
Why is troposphere higher at equator?
The troposphere is thicker over the equator than the poles because the equator is warmer. Heat differential on the planet’s surface causes convection currents to flow from the equator to the poles. Thus the simple reason is thermal expansion of the atmosphere at the equator and thermal contraction near the poles.
What attaches itself to the jet stream and in a sense tells you where the?
What attaches itself to the jet stream and, in a sense, tells you where the stratosphere begins? The position of the jet stream also indicates the location of high- and low-pressure systems, moving them from place to place.
