The polar jet stream expresses seasonal change. <em>The change in the </em><em>polar jet stream</em><em> from summer to winter position causes </em><em>cooler temperatures</em><em> farther south and causes </em><em> storms</em><em> to move more rapidly. Option 4.</em>
<h3 /><h3>Jet Streams</h3>
- A jet stream is a strong and narrow air stream concentrated along the horizontal axis in the troposphere.
- The stream wide is about 200 km, and its thickness ranges between 5,000 and 7,000 m.
- The strongest winds are in the central region of the stream, known as the jet core, with a speed of about 120 km/hour.
<h3>Types</h3><h3 />
- There are five jet stream types.
- Two polar streams ⇒ one of them in the northern hemisphere and the other one in the southern hemisphere.
- Two subtropical streams ⇒ one of them in the northern hemisphere and the other one in the southern hemisphere.
Both of them are west streams. And the polar ones are stronger than the subtropical ones.
- The tropical stream that comes from the east.
<h3 /><h3>Polar Jet Stream</h3><h3 />
- In the northern hemisphere, the polar jet stream affects mainly the Iberian peninsula.
- It gets formed in the convergence region, where the cooler winds from the Pole and the warmer winds from the Equator meet.
- This stream surrounds the Earth making several waves on its course.
- It occurs a seasonal balance between the winter and summer
→ Winter ⇒ The polar jet stream places between 35 and 40º latitude.
→ Summer ⇒ The polar jet stream is placed at about 50º latitude.
Following this seasonal change, from summer to winter cooler air masses reach lower latitudes and might be the cause of severe winter storms.
According to this framework, we can assume that <em>the </em><em>change</em><em> in the </em><em>polar front jet stream</em><em> from summer position to winter position causes </em><em>cooler temperatures</em><em> farther </em><em>south </em><em>and causes </em><em>storms</em><em> to move more rapidly. </em>
The correct option is (4).

Producers: living things that make their own food through a process called photosynthesis
Autotrophs: an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.
Heterotrophs: an organism deriving its nutritional requirements from complex organic substances.
Photo autotrophs: organisms that carry out photosynthesis. Using energy from sunlight, carbon dioxide and water are converted into organic materials to be used in cellular functions such as biosynthesis and respiration.
