What else can I help you with?
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.
What jetstream brings in cold dry air?
Polar Jet Stream.
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.
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.
How does the polar front influence the development of the polar-front jet stream?
The northernmost (and/or southernmost) of the various jet streams that circle the Earth.
What effect does the polar jetstream Have on temperature?
The polar jet stream significantly influences temperature by acting as a boundary between cold polar air and warmer air from the tropics. When the jet stream dips southward, it can bring colder Arctic air to lower latitudes, resulting in cooler temperatures in those regions. Conversely, when it shifts northward, it allows warmer air to move into areas that would typically be cooler, leading to higher temperatures. This dynamic movement of the jet stream can create extreme weather patterns and temperature fluctuations.
How does the polar easterlies and the jet stream work together to affect the weather in the US?
The polar easterlies are cold winds that flow from the polar regions toward the equator, while the jet stream is a fast-flowing river of air high in the atmosphere that influences weather patterns. Together, they can interact to create significant weather changes in the U.S., particularly in winter. When the polar easterlies are strong, they can push the jet stream southward, bringing cold Arctic air into the continental U.S., which can lead to frigid temperatures and winter storms. Conversely, if the jet stream is positioned further north, it can allow for warmer air to move in, moderating temperatures in many regions.
What are the two jet streams in the Southern Hemisphere?
The two jet streams in the Southern Hemisphere are the Subtropical Jet Stream and the Polar Jet Stream. The Subtropical Jet Stream is located closer to the equator and the Polar Jet Stream is found closer to the South Pole. These high-altitude, fast-flowing air currents play a significant role in influencing weather patterns in the Southern Hemisphere.
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.
