NIFE WEATHER QUESTIONS AND ANSWERS ALREADY PASSED What are the percentages of gases in pure, dry air? 78% nitrogen 21% oxygen 1% other gases What percent is water vapor in the atmosphere? 0-5% by volume What is the troposphere? Layer adjacent to the Earth's surface Where does all weather occur? Troposphere In the troposhpere, what happens to the temperature with an increase in altitude? Temperature decreases What are the winds like in the troposphere? Winds are light near ...

What is the pressure gradient defined as? - -The rate of pressure change in a direction perpendicular to the isobars What type of vertical atmospheric circulation is associated with a low-pressure system? - Air will ascend (insufficient pressure to keep air at the surface) and try to converge at the center of the lowpressure, which also produces wind Define Atmospheric Pressure (Barometric Pressure) - -Pressure exerted on a surface by the atmosphere due to the weight of the column of air di...

What are the characteristics of the flow of air around high pressure systems? Outward Downward Clockwise What are the characteristics of the flow of air around low pressure systems? Inward Upward Counterclockwise What is a Trough Line? An elongated area of low pressure. (Air rises in this area) (It is conducive to cloudiness and precipitation) What is a Ridge Line? An elongated area of high pressure. (Air moving out of a high depletes the quantity of air - therefore these are areas of ...

Define Wien's Law - The hotter an object, the shorter the wavelength at maximum emission. (The hotter the object the brighter) After a cold front passes what happens to dew point? - it drops, as cold air is typically dry Centripetal force wind - right angles to the wind, in towards the center of curvature ex. hurricanes Convection is the process that? - involves mixing in a fluid Coriolis effect - The effect of Earth's rotation on the direction of winds and currents. Define a category fi...
