The polar jet stream is a high-altitude air current found in the upper atmosphere near the Earth's poles. It meanders and shifts in response to differences in temperature and pressure, influencing weather patterns. It plays a key role in steering storm systems and determining the track of weather systems in mid-latitudes.
Put simply, the jet stream mixes the cold polar air with warm air from the tropics and vice versa, meaning climates across the UK are more temperate. This can have a number of effects, depending on the position of the jet stream in relation to the UK, and the direction and angle of travel of the jet stream. For example, if it is south of the UK, this will cause colder weather. If, on the other hand, it is north of the UK, the he opposite will happen - warmer weather will ensue. When the jet stream is positioned directly over the UK, the weather will be wetter and windier than usual.
The convection cell that connects the polar jet stream and the subtropical jet stream is known as the Ferrel Cell. This cell operates between the polar cell and the Hadley cell, facilitating the movement of air and influencing weather patterns. The Ferrel Cell plays a crucial role in the dynamics of the mid-latitude atmosphere, where it helps to transfer energy and moisture between these two jet streams.
The jet stream moves faster in winter primarily due to the larger temperature differences between the polar regions and the equator. During winter, the polar air masses become much colder, while the warmer air from the south remains relatively stable. This steep temperature gradient enhances the wind speeds of the jet stream, causing it to flow more rapidly. Additionally, the winter months lead to a more pronounced and stable jet stream pattern, contributing to its increased speed.
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.
Yes, there is a jet stream in the Southern Hemisphere known as the Southern Hemisphere Polar Jet Stream. It flows from west to east and its strength and position vary throughout the year.
A continental jet-stream travels parallel to the equator - a polar jet-stream travels in a north/south direction.
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.
