The northern polar jet stream is a fast-flowing, narrow air current located in the upper troposphere. It forms at the boundary of cold polar air and warmer air masses to the south. Its path meanders due to the temperature differences, guiding weather systems and influencing patterns of high and low-pressure systems.
What else can I help you with?
How is the jet streem related to convection?
The jet stream is a narrow band of strong winds in the upper atmosphere that is driven by the temperature difference between air masses. Convection is the transfer of heat through the movement of fluid (in this case, air). The jet stream is influenced by the temperature contrasts created by convection, particularly between the polar and tropical air masses.
What is between the north and south ploe and 60 begres latitude buzzing along in cold dry dense air horizanatl air currens are called?
That would be the polar jet stream. It is a fast-flowing, narrow air current found in the upper atmosphere between the north and south poles around 60 degrees latitude. The polar jet stream plays a significant role in driving weather patterns and can have a major impact on surface weather conditions.
Which of these is a high pressure band of air blowing from west to east?
The high pressure band of air blowing from west to east is known as the jet stream. The jet stream is a fast-moving ribbon of air found in the upper levels of the atmosphere. It plays a significant role in influencing weather patterns and can have impacts on aviation and climate.
What is an aircraft the achieve forward propulsion by expelling a stream of fluid called?
An aircraft that achieves forward propulsion by expelling a stream of fluid is called a jet aircraft. Jet engines, such as turbojets or turbofans, expel high-speed exhaust gases to generate thrust and propel the aircraft forward.
Which is the high pressure band of air blowing from west to east?
The high pressure band of air blowing from west to east is known as the subtropical jet stream. It is located at high altitudes in the atmosphere and affects weather patterns in the mid-latitudes. The subtropical jet stream is stronger in the winter and weaker in the summer.
What two major jet streams are in the northern hemisphere?
The Polar Jet Stream and the Subtropical Jet Stream are the two strongest jet streams in the Northern Hemisphere. The Southern Hemisphere has two major jet streams like the Northern Hemisphere.
Which is stronger polar jet stream or subtropical jet stream?
The polar jet stream is generally stronger and faster-moving than the subtropical jet stream. The polar jet stream forms at higher latitudes and is located closer to the poles, while the subtropical jet stream is located at lower latitudes. The polar jet stream is associated with larger temperature contrasts and stronger pressure gradients, resulting in stronger winds compared to the subtropical jet stream.
In the Northern Hemisphere the jet stream brings cold weather conditions from the north and the jet stream brings warm weather conditions from the south.?
polar; subtropical
What is the difference between a continental jet stream and a polar jet stream?
A continental jet-stream travels parallel to the equator - a polar jet-stream travels in a north/south direction.
Where does the polar jet stream blow all year around?
The polar jet stream blows near the polar regions, at around 60 degrees latitude in both the Northern and Southern Hemispheres. It can shift its position seasonally, moving south in the winter and north in the summer.
What statement is true of jet streams A. The subtropical jet stream lies between the westerlies and polar easterlies. B. The subtropical jet stream flows to the east while the polar jet stream flows?
A. The subtropical jet stream lies between the westerlies and polar easterlies; this statement is true. B. The polar jet stream typically flows to the east, while the subtropical jet stream flows towards the west.
How many jet streams are in Earths northern hemisphere?
There are typically two main jet streams in the Earth's northern hemisphere: the polar jet stream and the subtropical jet stream. These high-altitude, fast-flowing air currents play a significant role in shaping weather patterns.
Where are the major jet streams in the ocean?
There are 2 jet streams in the northern hemisphere and 2 in the southern hemisphere. They are known as the subtropical jet stream and the polar jet streams subsequently for get side.
which is true of jet streams?
The polar jet stream is generally stronger than the subtropical jet stream
What is true about a jets stream?
The polar jet stream is generally stronger than the subtropical jet stream
What determines how far south the the cold air from the north pole travels?
The jet stream
What accompanies a cold spell in Minnesota?
Minnesota receives arctic air when the polar jet stream moves south across Canada.
