NIFE Weather Exam Questions and

Verified Answers 100% Guaranteed Pass


What is the composition of dry air? - ✔✔78% nitrogen

21% oxygen

1% mixture of 10 other gases

How much of the atmosphere, by volume, is composed of water? - ✔✔0 to

5%

What are condensation nuclei? - ✔✔-Nongaseous substances such as dust

and salt particles, pollen, etc



-Water molecules condense on these particles and form clouds

What layer of the atmosphere is adjacent to the Earth's surface? -

✔✔Troposphere

List some characteristics of the troposphere. - ✔✔-Adjacent to Earth's

surface

-Average height of 36,000'MSL above the US

-Becomes less dense with altitude

,©JOSHCLAY 2024/2025. YEAR PUBLISHED, 2024.
-Temperature decreases with increasing altitude

-Nearly all weather occurs here

-Wind velocity increases with altitude

What is the tropopause and where is it found? - ✔✔-Transition zone

between the troposphere and

stratosphere

-Temperature is constant with altitude

-Jet stream occurs right below (strongest winds)

Define Atmospheric Pressure (Barometric Pressure) - ✔✔-Pressure

exerted on a surface by the atmosphere due to the weight of the column of

air directly above that surface

-Pressure always decreases with altitude (decreases more rapidly at lower

altitudes because of decreasing density)

What are the two units of measurement for atmospheric pressure? - ✔✔-in-

Hg: measure of the height of a column of mercury that can be supported by

atmospheric pressure



-Millibar: direct representation of pressure (force/unit area)



-Normal sea level pressures range from 28-31 in-Hg (960-1060mb)

,©JOSHCLAY 2024/2025. YEAR PUBLISHED, 2024.
Surface analysis charts use _______ as the reference pressure level for

isobars. - ✔✔-MSL barometric pressure (to provide a common reference)



-Allows meteorologists to track weather systems as they move across the

country

What type of vertical atmospheric circulation is associated with a high-

pressure system? - ✔✔Air will descend (downward force exerted by high

pressure) and diverge, which produces wind

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 low-pressure, which

also produces wind

What effect does the Coriolis Force have on wind as it moves horizontally

into/out of high/low pressure systems? - ✔✔-Wind will circulate as it moves

out of a High-pressure system and into a Low-pressure system

-Clockwise out of a high-pressure system (in the northern hemisphere)

-Counterclockwise into a low-pressure system (in the northern hemisphere)

What does the spacing of isobars indicate? - ✔✔-Rate of pressure change

over a horizontal distance

, ©JOSHCLAY 2024/2025. YEAR PUBLISHED, 2024.
-Closer the spacing, the greater the change

-Pressure Gradient Force

What is the pressure gradient defined as? - ✔✔-The rate of pressure

change in a direction perpendicular to the isobars

What is the initiating force of all winds? - ✔✔Pressure Gradient Force

When isobars are close together, the Pressure Gradient Force is ______,

and when isobars are far apart, the Pressure Gradient Force is

_______________. - ✔✔greater/steeper



more shallow/weaker

What are the conditions of a standard day? - ✔✔-29.92 in-Hg (1013.2mb)

-15 deg C (59F)

-Standard day conditions at sea level

What is the standard lapse rate for pressure and temperature? - ✔✔-A

1,000' increase in altitude will cause.....

Pressure to decrease by 1.0 in-Hg (34mb)

Temperature to decrease by 2 deg C (3.57F)
