Question 1174Navigation General

70% to pass

Wind velocity varies _______________.

A inversely with the barometric pressure
B directly with the temperature of the air mass
C directly with the pressure gradient
D inversely with the absolute humidity
AI Explanation

The correct answer is C) directly with the pressure gradient. The wind velocity is directly proportional to the pressure gradient, which is the change in atmospheric pressure over a given distance. A higher pressure gradient leads to faster wind speeds as air flows from high-pressure to low-pressure areas. This is a fundamental principle of meteorology and fluid dynamics governing atmospheric circulation. The other options are incorrect because: A) wind speed does not vary inversely with barometric pressure, B) wind speed is not directly related to air temperature, and D) wind speed is not inversely related to absolute humidity. These factors may influence wind patterns, but the primary driver of wind velocity is the pressure gradient.
