The winds blow from sub tropical high pressure towards the sub polar low pressure in South-West to North-East direction are called as :

Question

Accepted Answer

The correct answer to the question is Option 2: Westerlies (Northern Hemisphere). Let's provide a detailed explanation to justify why this option is correct and why the other options are incorrect.

### Explanation for Option 2: Westerlies (Northern Hemisphere)

1. **Definition and Direction**: The Westerlies are prevailing winds that blow from the subtropical high-pressure areas towards the subpolar low-pressure areas. In the Northern Hemisphere, these winds generally move from the southwest to the northeast. This aligns with the question's description of winds blowing from the southwest to the northeast direction.

2. **Geographical Context**: The Westerlies are found between 30 and 60 degrees latitude in both hemispheres. In the Northern Hemisphere, they are responsible for much of the weather patterns experienced in the mid-latitudes, including parts of North America, Europe, and Asia.

3. **Coriolis Effect**: Due to the Earth's rotation, the Coriolis effect causes these winds to deflect to the right in the Northern Hemisphere, resulting in a southwest to northeast flow.

### Explanation for Why Other Options are Incorrect

1. **Option 1: North-East Trade Winds**
   - **Direction**: The North-East Trade Winds blow from the northeast to the southwest, not from the southwest to the northeast. They are found in the tropics, between the equator and 30 degrees north latitude.
   - **Pressure Systems**: These winds move from the subtropical high-pressure areas towards the equatorial low-pressure zone, which does not match the subpolar low-pressure destination described in the question.

2. **Option 3: South-East Trade Winds**
   - **Direction**: The South-East Trade Winds blow from the southeast to the northwest in the Southern Hemisphere. This is opposite to the direction specified in the question.
   - **Hemispheric Location**: These winds are located in the Southern Hemisphere and are not relevant to the Northern Hemisphere's wind patterns described in the question.

3. **Option 4: Westerlies (Southern Hemisphere)**
   - **Hemispheric Location**: While the Westerlies also exist in the Southern Hemisphere, the question specifically pertains to the Northern Hemisphere, as indicated by the correct answer being Option 2.
   - **Direction**: In the Southern Hemisphere, the Westerlies blow from the northwest to the southeast, which does not match the southwest to northeast direction specified in the question.

In conclusion, Option 2: Westerlies (Northern Hemisphere) is the correct answer because it accurately describes the wind pattern that blows from the southwest to the northeast from subtropical high-pressure areas towards subpolar low-pressure areas in the Northern Hemisphere.
