What phenomenon results from the wind blowing outwards in a high pressure system?

• A. Heavy rainfall
• B. Clear skies with calm weather
• C. Strong gales and storms
• D. Increased humidity

Answer: (B)

A phenomenon resulting from wind blowing outwards in a high-pressure system is characterized by clear skies with calm weather. In high-pressure areas, the air descends, which warms and dries it as it compresses. This leads to a lack of clouds and precipitation, resulting in stable atmospheric conditions. The outward flow of air also contributes to the dispersal of any moisture that may be present, further promoting the clear skies associated with high-pressure systems.

In contrast, heavy rainfall typically occurs in low-pressure systems, where rising air cools, allowing moisture to condense into clouds and precipitation. Strong gales and storms are generally associated with low-pressure areas, where air converges and rises rapidly, creating turbulent conditions. Increased humidity is also more characteristic of low-pressure systems, where air is often moist and conducive to cloud formation and precipitation. Thus, the correct answer reflects the meteorological stability associated with high-pressure systems.
