The polar jet stream is, on average, 10 kilometers (6 miles) in the atmosphere, which places it near the top of the Troposphere. The subtropical jet stream tends to be a little higher - around 13 kilometers - because the air is warmer. Warmer air takes up more space, therefore the top of the atmosphere is higher.
Typically the jet stream is found between 200 and 300 hectopascals (hPa, which is equivalent to millibars, or mb). In atmospheric science, the altitude in the atmosphere is often given in terms of what the atmospheric pressure is for reasons that we won't get into. In any event, these are the levels we look at for the jet stream.
The layer of the atmosphere where the jet stream resides is not completely clear. The most common definition given for the top of the troposphere is where the temperature stops decreasing and begins increasing. This is almost always at altitudes above 200mb. Therefore, the jet stream is generally found in the troposphere, near the tropopause. It is rarely as high as the stratosphere.
Jet streams are fast flowing, narrow, meandering air currents in the atmospheres of some planets, including Earth. On Earth, the main jet streams are located near the altitude of the tropopause and are westerly winds (flowing west to east).

you mean jet streams...or thermals?

They're called 'jet streams'.
No, the jet stream is an area of very strong wind located in the middle-upper part of the troposphere. It exists for a variety of reasons, but its presence influences the general circulation (wind) of the atmosphere very little.
