Jet streams are narrow meandering bands of swift winds that blow in the mid-latitudes near the tropopause and encircle the globe. They are high-altitude wind systems with speeds reaching up to 200 mph (322 km/h) and can have a significant impact on weather patterns.
Below is a detailed explanation of each option and why option 'C' is the correct answer:
a) Wind systems with a pronounced seasonal reverse in direction:
- This option is not correct because jet streams do not have a pronounced seasonal reverse in direction. Jet streams generally blow from west to east, but their exact location and strength can vary throughout the year.
b) Winds blowing from the subtropical high-pressure belts towards the subpolar low-pressure belts:
- This option is not correct because it describes the surface winds known as trade winds, not the jet streams. Trade winds blow from the subtropical high-pressure belts towards the equator, while the jet streams flow in the opposite direction.
c) Narrow meandering bands of swift winds which blow in the mid-latitudes near the tropopause and encircle the globe:
- This option is correct. Jet streams are indeed narrow and meandering bands of swift winds that occur in the mid-latitudes, generally between 30 and 60 degrees north and south of the equator. They are located near the tropopause, which is the boundary between the troposphere and the stratosphere. Jet streams encircle the globe and play a crucial role in shaping weather patterns.
d) Winds blowing from the subpolar low-pressure belts towards the subtropical high-pressure belts:
- This option is not correct because it describes the surface winds known as prevailing westerlies, not the jet streams. Prevailing westerlies blow from the subpolar low-pressure belts towards the subtropical high-pressure belts, while the jet streams flow in the opposite direction.
In conclusion, option 'C' is the correct answer because it accurately describes jet streams as narrow meandering bands of swift winds that blow in the mid-latitudes near the tropopause and encircle the globe.
