← GeographyWhich mechanism minimizes coastal fog formation during increased offshore upwelling events?
A)Descending air mass suppression near shore✓
B)Ocean temperature exceeding dew point
C)Stable boundary layer inversion formation
D)Reduced evaporation driving saturation
💡 Explanation
When upwelling increase, a descending air mass suppression along the coast is induced, decreasing atmospheric mixing due to higher pressure aloft, preventing moisture rising and saturation. Therefore the suppressing air minimizes fog, rather than elevated ocean temperature or reduced evaporation requiring changes at interface.
