Which of the two is associated with high speed winds : reduced air pressure or increased air pressure ?

Explanation

To determine which of the two conditions—reduced air pressure or increased air pressure—is associated with high-speed winds, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Air Pressure**:
- Air pressure is the weight of the air above a certain point. It can vary based on temperature and altitude.

2. **Identifying Low and High Pressure**:
- Low pressure occurs when warm air rises. As the warm air rises, it leaves behind a space that needs to be filled, creating a low-pressure area.
- Conversely, high pressure occurs when cool air sinks, which leads to a denser air mass that exerts more pressure.

3. **Movement of Air**:
- Air moves from areas of high pressure to areas of low pressure. This movement is what we perceive as wind.
- When there is a significant difference between high and low pressure, the air moves more rapidly to equalize the pressure difference.

4. **Conclusion**:
- Since high-speed winds are generated when air rushes into a low-pressure area, we conclude that high-speed winds are associated with reduced air pressure.

Thus, the answer is **reduced air pressure**.
