Answer:
Jet stream
Explanation:
Jet stream is fast moving air or wind that blows horizontally through the upper layers of the troposphere, generally from west to east. It develops where air masses of different temperatures meet. The greater the difference in temperature, the faster the wind speed.
Jet stream has the following characteristics;
- The winds blow from west to east
- The flow often shifts to the north and south.
- They follow the boundaries between hot and cold air.
Wind is the answer to this.
Polar.
The polar regions are cold year round because of the chill, polar air has a low capacity to evaporate water vapor in the air. The sun angle is fairly low throughout the year in polar areas. A significant amount of solar radiation that does reach the polar surface is reflected back into space.
