jet stream
The main jet streams are located near the tropopause, the transition between the troposphere (where temperature decreases with altitude) and the stratosphere(where temperature increases with altitude).
The upward transition zone in the US is typically found in the northern part of the country, closer to the Canadian border. This zone marks the shift from a temperate climate to a colder subarctic climate, with shorter growing seasons and colder temperatures. States such as Minnesota, Wisconsin, and Maine are examples of areas where this transition zone can be observed.
The altitude of the jetliner is 6 miles.
Because pressure decreases as you go up in altitude and increases when you go down in altitude. Hope this helped!
The diference is simple, the transition altitude is the altitude above sea level at wich the aircraft change from the use of altitude to the use of flight level. When operating above the transition altitude, the aircraft altimeters pressure seting is normally adjusted to the standard pressure setting wich is 1013 millibars in europe, or 29.92 inches of mercury in US, or Canada. There the aircraft altitude will be expressed as a flight level.
The Transition Altitude (TA) in France is generally 3000 FT AGL (above ground level). But most controlled airspace (TMA) uses another TA (4000, 5000 or 6000). The TA is printed on the official maps. Or you cold listen to ATIS. Or just ask a controller when unsure ...
QNE is pressure altitude, the pressure as if it were ISA conditions regardless of actual conditions, used above transition altitude. QNH is the actual pressure reduced to sea level.
Transition can be used as a noun and a verb. Noun: e.g. process of change from one style to another. Verb: to make a transition. (This usage is mostly used in the US)
