Polar front - Wikipedia
In meteorology, the polar front is the weather front boundary between the polar cell and the Ferrel cell around the 60° latitude, near the polar regions, in both hemispheres. At this boundary a sharp gradient in temperature occurs between these two air masses , …
Polar front | Jet Stream, Atmospheric Pressure & Temperature
Polar front, in meteorology, the transition region separating warmer tropical air from colder polar air in the mid-latitudes. This region possesses a strong temperature gradient, and thus it is a reservoir of potential energy that can be readily tapped and converted into the kinetic energy

极锋急流 - 百度百科
极锋急流（polar front jet）又称温度急流或北支急流。与中高纬度的高空行星锋区（极锋）相联系的强风带。其轴出现高度为8-10km，大约在300hpa附近。急流中心附近的风速平均约60m/s,但它的中心强度和南北位置有明显的季节变化。
Fronts: Atmosphere – The Polar Front – Weather in a Tank
In the atmosphere, the transition from warm, equatorial air to cold polar air is not gradual, but occurs rather abruptly in mid-latitudes where tropical and polar air masses meet at the polar front. Everyday weather is often associated with undulations of this frontal surface. Here we will study the observed structure of the polar front.

The polar front is the junction between the Ferrell and Polar cells. At this low pressure zone, relatively warm, moist air of the Ferrell Cell runs into relatively cold, dry air of the Polar cell. The weather where these two meet is extremely variable, …

What is a Polar Front? - Kids Fun Science
A polar front is an area where cold polar air mass meets a warm tropical air mass. The line between these two air masses can be thousands of miles long.
Polar front jet stream | Atmospheric Dynamics, Global Winds, Jet ...
polar front jet stream, a belt of powerful upper-level winds that sits atop the polar front. The winds are strongest in the tropopause, which is the upper boundary of the troposphere, and move in a generally westerly direction in midlatitudes.
polar front - Infoplease
polar front, zone of transition between polar and tropical air masses. Its average position during the winter is at about 30° lat. and during the summer at about 60° lat. In the N Atlantic Ocean, for example, the polar front can often be traced as a
