Multiple choice

The spatial variations in the wind velocity in a weather map can be best explained by a reference to the distribution of

  1. barometric gradient

  2. cyclones and depressions

  3. fronts and air masses

  4. highs and low

A Correct answer
Explanation

Wind velocity varies spatially due to pressure differences in the atmosphere. The barometric gradient (rate of pressure change over distance) directly controls wind speed - steeper pressure gradients produce stronger winds as air flows from high to low pressure areas. This is why isobars on weather maps are closely spaced where winds are strong.
