Which of the following statements best describe 'tropical Easterlies'...
The correct answer is option 'B': 2 and 3 only.
The 'tropical Easterlies' are a type of wind pattern that occurs in the tropical regions of the Earth. They are also known as the 'trade winds' because they were historically used by traders to navigate their ships.
Here is a detailed explanation of the statements:
1. These winds blow from subtropical high-pressure belts towards sub-polar low-pressure belts.
- The tropical Easterlies blow from the subtropical high-pressure belts, which are located around 30 degrees latitude in both hemispheres. These high-pressure belts are created by the sinking of cool, dry air from higher altitudes.
- The winds then flow towards the sub-polar low-pressure belts, which are located around 60 degrees latitude in both hemispheres. These low-pressure belts are created by the rising of warm, moist air near the poles.
2. These get deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.
- The rotation of the Earth causes the Coriolis effect, which deflects the path of moving objects, including winds.
- In the Northern Hemisphere, the tropical Easterlies are deflected to the right as they move towards the equator. This is due to the Coriolis effect caused by the Earth's rotation.
- In the Southern Hemisphere, the tropical Easterlies are deflected to the left as they move towards the equator. This is also due to the Coriolis effect.
3. These are also known as trade winds.
- The tropical Easterlies are indeed known as trade winds. They were named so because they were used by traders in the past to navigate their ships across the oceans.
So, among the given statements, statements 2 and 3 accurately describe the characteristics of tropical Easterlies. Hence, the correct answer is option 'B': 2 and 3 only.

Which of the following statements best describe 'tropical Easterlies'...
- Winds blowing from subtropical high-pressure belts towards sub-polar low-pressure belts are known as westerlies. So, statement (1) is not correct.
- These winds should have blown from the north to south in the Northern Hemisphere and south to north in the Southern Hemisphere, but they get deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere due to the Carioles effect and Ferrell's law. Thus, they blow as north- eastern trades in the Northern Hemisphere and south-eastern trades in Southern Hemisphere. So, statement (2) is correct.
- They are also known as Trade winds, and they blow steadily in the same direction. They are noted for consistency in both force and direction. Trade winds have been used by captains of sailing ships to cross the world's oceans for centuries and enabled colonial expansion into the Americas and trade routes to become established across the Atlantic and Pacific oceans. So, statement (3) is correct.
Therefore, the correct answer is b.
