The 300-mb map is considered the best choice for observing the details of the polar jet stream because it is the altitude where the jet stream is located. This map also shows the wind speed and direction, as well as areas of atmospheric divergence and convergence associated with the jet stream. The other maps are located at lower altitudes and do not provide as much detail on jet stream characteristics.
