It varies from day to day. Usually there are two in the northern hemisphere and two in the southern. The occur because the Earth's rotational speed at the equator is greater than the speed of sound, while it's zero at the poles.
Jet streams. They are high altitude bands of fast-moving air that flow from west to east in the upper troposphere and lower stratosphere. Jet streams are driven by a combination of temperature gradients, the Earth's rotation, and atmospheric pressure differences.
There are typically two main jet streams in the Earth's northern hemisphere: the polar jet stream and the subtropical jet stream. These high-altitude, fast-flowing air currents play a significant role in shaping weather patterns.
Jet Streams
Jet streams are fast flowing, narrow, meandering air currents in the atmospheres of some planets, including Earth. On Earth, the main jet streams are located near the altitude of the tropopause and are westerly winds (flowing west to east).
Tpp (tropopause)
There are typically four jet streams on Earth: two in each hemisphere. These are the polar jet streams and the subtropical jet streams. Polar jet streams are found closer to the poles, while subtropical jet streams are located closer to the equator.
There are typically six jet streams on Earth: three in each hemisphere. The strongest and most well-known ones are the polar jet streams and the subtropical jet streams. These high-altitude, fast-flowing air currents have a significant impact on weather patterns.
There are 2 jet streams in the northern hemisphere and 2 in the southern hemisphere. They are known as the subtropical jet stream and the polar jet streams subsequently for get side.
There are typically four main jet streams in Earth's atmosphere: two polar jet streams, located near the poles, and two subtropical jet streams, located closer to the equator. These jet streams are high-altitude, fast-flowing air currents that play a significant role in shaping weather patterns.
jet streams
The Polar Jet Stream and the Subtropical Jet Stream are the two strongest jet streams in the Northern Hemisphere. The Southern Hemisphere has two major jet streams like the Northern Hemisphere.
Jet Streams are fast blowing winds above the troposphere. The blow at speeds of upto 120kmph. When two jet streams collide it causes storms.

My balls
Meteorologists use weather balloons, aircraft data, satellites, and computer models to study jet streams. These tools help them monitor the speed, direction, and strength of jet streams in the atmosphere.
