GEOG 1900 Exam #2 - (Questions & Accurate Answers)

What instruments are used to measure wind? Correct Ans -
Anemometer, Radiosondes (weather balloons), Tethersonde, Doppler Radar,
Wind Vane

Identify the general characteristics associated with winds and pressure
gradients Correct Ans - Pressure Gradient: Drives winds from high to
low pressure.

Coriolis Effect: Earth's rotation deflects wind direction.

Isobars: Map lines indicate wind strength.

High/Low Pressure: High = clear weather, descending air; Low = stormy
weather, ascending air.

Wind Characteristics: Speed by pressure, direction by Coriolis effect.

Local Winds: Include land/sea and mountain/valley breezes.

Explain how temperature affects air pressure near the ground and high up in
the sky when it warms up or cools down Correct Ans - General Rule:
Higher temperature, lower pressure; lower temperature, higher pressure.

Warming Air:
Surface: Warmer air, lower pressure due to expansion.
Aloft: Expansion leads to lower pressure at higher altitudes.

Cooling Air:
Surface: Cooler air, higher pressure due to contraction.
Aloft: Contraction results in higher pressure at higher altitudes.

What are the features of land and sea breezes? Explain the forces causing
pressure differences and how they make the wind change directions
Correct Ans - Land Breeze (Night):
Characteristics: Nighttime land cools faster, higher pressure over water, lower
over land.
Forces: Breeze from sea to land.

, Sea Breeze (Day):
Characteristics: Daytime land heats faster, higher pressure over land, lower
over sea.
Forces: Breeze from land to sea.

Identify examples of other types of local winds and the general characteristics
of each Correct Ans - Santa Ana Winds:

Hot, dry winds in SoCal, fall/winter.
Cause: High-pressure -> winds to lower pressure.
Impact: Raises wildfire risk due to dry conditions.

Foehn Winds:

Warm, dry downslope winds on mountains.
Cause: Air cools, warms adiabatically descending.
Impact: Rapid temp increase, dries air.

Identify the characteristics associated with the Coriolis force Correct Ans
- Coriolis Force Characteristics:

Definition: Apparent force from Earth's rotation.

Effect on Moving Objects: Objects deflect right (N. Hemisphere) or left (S.
Hemisphere).

Latitude Influence: Stronger at poles, weaker at equator.

Global Impact: Affects wind and ocean currents.

Not Real Force: Result of Earth's rotation, not a physical force.

What are the characteristics of cyclones and anticyclones in the upper
atmosphere? Include pressure, wind speed, and forces involved Correct
Ans - Cyclones in the Upper Atmosphere:

-Pressure: Low-pressure systems.
-Winds: Generally faster winds.
