jet streams Located in the upper troposphere or stratosphere, strong and narrow in the air. Usually thousands of kilometers long, hundreds of kilometers wide, several kilometers thick. The long axis of the jet center known as the jet axis, it is nearly horizontal. Jet axis in the vicinity of strong wind shear, vertical shear of about 5 to 10 meters per kilometer / second, horizontal shear of about 5 meters per hundred kilometers / second. By the World Meteorological Organization, the wind speed limit on the jet axis is 30 m / sec. Jet twists and turns, around the entire hemisphere, the wind speed on the jet axis is not uniform, with one or more wind speed maximum center. In the wind speed is less than 30 meters / second at the break. Under normal circumstances, the central jet velocity of 50 to 80 m / s, sometimes up to 100 to 150 m / s, in the winter occasionally up to 150 ~ 180 m / sec. Jet axis branches in some regions, two jet convergence in some areas. Near the tropopause from the pressure surface (such as 200 hPa) and mean zonal wind speed distribution (see atmospheric circulation), we can see the distribution and structure of the jet. The jet with the atmosphere of heat and angular momentum transport related, was an important part of the global atmospheric circulation. Rapids often associated with the frontal zone, so the occurrence of weather systems and the development has a close relationship. Weather in the jet stream is an important research topic.

Polar Front Jet, also known as temperate jet. It is linked to the polar front and the westerly jet stream (Figure 1). By the thermal wind theory (see the balance of atmospheric motion), the polar front in the vicinity of the strong position of the horizontal temperature gradient (600 hPa in the polar front near the frontal zone), rapid increase in westerly wind speed with height to near the tropopause, the temperature gradient disappears, westerly speed no longer increases, and then up the temperature gradient change of direction, speed of westerly winds weaken with height. Therefore, the polar front jet stream about 600 hPa in the polar front over the frontal zone near the tropopause, the intensity and location vary widely. It and the upper front area of the polar front along wavy around the hemisphere. Troughs of the wave front with the upper troposphere general long-wave trough peak corresponds to slightly more than long-wave radiation big wave. Center axis of strong wind moving generally from west to east, in the development process is usually long-wave trough moved to the long wave trough, moving speed faster than the long-wave system. Polar Front Jet has obvious phenomenon of branching and merging in their branch area (also known as export zones) to the left, the left front of the jet center there is the dynamic conditions of extratropical cyclone (upper divergence), often in the cyclone at the occurrence and development. Also, cyclones along the jet axis trend. Jet activity area so stormy weather. In the northern hemisphere winter, the subtropical jet usually three waves of the situation around the Hemisphere: The wave crest, respectively, in southern Japan, North America, Eastern and eastern Mediterranean, south of the trough, respectively, in the Qinghai-Tibet Plateau, the Northeast Pacific and Northeast Atlantic. The three-wave structures are often associated with the polar front jet stream branches and merging between the composition (Figure 2), at the confluence of more than three waves in the structure of the subtropical jet wave ridge. Branch of the phenomenon of convergence in East Asia most clearly in the branch over the Tibetan Plateau, the convergence in southern Japan, to the Pacific Ocean on another branch. The reason why Japan's most powerful jet stream over southern jet stream and where the confluence of these two related. Polar front jet and subtropical jet stream causes Atmospheric angular momentum balance can be described. Unit mass of air motion relative to the axis of the absolute angular momentum l = ω r Yan cos2e + urecos 嗘, where ω is the angular velocity of earth rotation, u is the east-west wind speed, φ is latitude, re is the Earth radius. Circulation due to the role of Hudson, the low-latitude warm air transported northward and then rose to high altitude, at high altitude without an external torque, the north block to maintain the air conveying the absolute conservation of angular momentum. Therefore, the west wind (u> 0) with the gas block of latitude (φ) increases with increasing. Latitude westerly winds due to the enhanced value of the increase is substantial, resulting in the subtropical latitudes of the subtropical jet stream over the produce. Formed in the jet, while jet axis to the polar regions south of the road where the accumulation of air in the sink, forming a middle and lower troposphere subtropical zone. As the polar front jet stream, mainly by large-scale atmospheric vortex transport energy to maintain. Mid-latitude troposphere, often in the upper atmosphere disturbance state, the emergence of various long-wave system. These disturbances in the net transfer of heat to the polar regions, while the horn again over the subtropical to the polar direction of the momentum transfer to the high latitude to low latitude and small angular momentum transport, resulting in angular momentum to the middle and high latitudes of the net transport. Therefore, the angular momentum in the mid-latitude concentration on the formation of a polar front jet stream. Stratospheric polar night jet polar night westerly jet referred to. In the winter hemisphere stratosphere, because of the long period of polar night, the atmosphere due to radiation cooling, but in the middle and low latitudes stratospheric ozone, but directly absorb the sun's ultraviolet radiation and temperature, the temperature of the formation of a strong gradient, resulting in a direct meridional circulation. Under the action of the Coriolis force, the flow of air to the poles gradually to the right side, in polar regions over the 50 to 60 km, forming a westerly jet, which can be extended down to 20 to 30 km altitude (Fig. 1 ), so at 50 hPa isobaric surface of the map, you can see this jet. Polar night jet around the polar regions, there are significant seasonal changes: the gradual establishment during autumn, winter has been maintained until the spring of the stratospheric sudden warming occurs when the last time, began to collapse (see the stratosphere and middle atmosphere circulation .) It is very important to the winter stratospheric circulation in a feature. Some years, in the winter stratospheric sudden warming will occur, leading to the collapse of polar night jet, but still the winter jet stream can resume. During the polar night jet crashes, mid-latitude sinking popularity, and high-level ozone down transmission. Fluctuations in polar night jet on the tropospheric circulation and weather with factors such as the relationship is very complex and further study.

Jet bridge
Surging Yellow River, the River flows through China's Inner Mongolia Autonomous Region Tuoketuo County Town, as the control line by the geological structure, suddenly turns sharply south, into the "Shanxi-Shaanxi Gorge" at home. In this deep valley, the Yellow River roared Pentium 725 km, until Yu doors after only slowly into the plain. "Shanxi-Shaanxi Gorge" in the provinces of Shanxi and Shaanxi, the junction of the Yellow River line. Yellow River water is slow here acute serpentine twists and turns, great, "Yellow ninety-nine bending" of the situation, when the width of the river is narrow, the formation of many dangerous shoals and rapids, "flyover jet" is one of the natural landscape . "Flyover jet" in the village and the kiosk bend county the stone stairs between the islands total length of 20 km. Quiet here, gullies and ravines, water potential rapidly, rough, and the endless rise amid the natural combination of heaven and earth, water and fog, Seven Wonders of the seamless, constitute a magnificent spectacle. "Fog fans wave" rapids in the canyon of the middle horizontal bar, several interlocking of boulder standing in the river heart. See, however, fell from the sky like the raging rapids of the Yellow River, sometimes rotated and sometimes frequently forward, sometimes out of self-Stream in, sometimes drill into the rock behind, smiling ten thousand beautiful waves, the momentum is quite spectacular. Especially in fast-flowing when the mist vacated, blotting out the sun, the King daunting. Every winter, where ice into a bridge, called the talent of the make. Its shape varies with arched, beveled, as well as unknown like, it dazzlingly. But see the bridge under the water potential of rapid, waves rolling in deafening. People called this kind of ice bridge "bridge" means the gods had made. Therefore, the ice bridge near the village bridge was renamed the village. Now the ice bridge downstream, the state has been built within the largest hydropower station in Shanxi Province - "Yellow River Bridge Station", so by brilliance of Shanxi, Shaanxi more canyons.
