The convection cell that lies to the north of the polar jet stream is the polar cell. This cell is one of the three major atmospheric circulation cells and is characterized by cold air descending at the poles, flowing towards the equator at the surface, and rising again at around 60 degrees latitude. The polar jet stream, which is a fast-flowing air current, forms at the boundary between the polar cell and the mid-latitude Ferrel cell.

A continental jet-stream travels parallel to the equator - a polar jet-stream travels in a north/south direction.
The jet stream
The polar easterlies are cold winds that flow from the polar regions toward the equator, while the jet stream is a fast-flowing river of air high in the atmosphere that influences weather patterns. Together, they can interact to create significant weather changes in the U.S., particularly in winter. When the polar easterlies are strong, they can push the jet stream southward, bringing cold Arctic air into the continental U.S., which can lead to frigid temperatures and winter storms. Conversely, if the jet stream is positioned further north, it can allow for warmer air to move in, moderating temperatures in many regions.

The Polar cell lies to the north of the Polar jet stream in the atmosphere. This cell is characterized by cool air sinking at the poles, moving towards lower latitudes at the surface, and then rising at around 60° latitude to complete the circulation loop.

The convection cell that lies to the north of the polar jet stream is called the Polar Cell. This cell is characterized by cold air descending near the poles and moving toward the equator at the surface, creating a circulation pattern that influences weather patterns in polar regions. The Polar Cell operates alongside the Ferrel Cell and the Hadley Cell, contributing to the overall atmospheric circulation.
The convection cell that connects the polar jet stream and the subtropical jet stream is known as the Ferrel Cell. This cell operates between the polar cell and the Hadley cell, facilitating the movement of air and influencing weather patterns. The Ferrel Cell plays a crucial role in the dynamics of the mid-latitude atmosphere, where it helps to transfer energy and moisture between these two jet streams.
The polar cell is the convection cell in the atmosphere that lies closest to the pole. It is characterized by air rising at 60 degrees latitude, moving towards the pole, cooling and sinking at the pole, and then flowing back towards 60 degrees latitude. This circulation pattern helps redistribute heat and moisture globally.

The jet stream is a narrow band of strong winds in the upper atmosphere that is driven by the temperature difference between air masses. Convection is the transfer of heat through the movement of fluid (in this case, air). The jet stream is influenced by the temperature contrasts created by convection, particularly between the polar and tropical air masses.
The Subpolar Low-Pressure Belt lies along the polar jet stream. It is found between 50 and 70 degrees North latitude. It consists of the Aleutian and Icelandic lows.
