SOLUTION
1. What instruments are Anemometer, Radiosondes (weather balloons), Tethersonde,
used to measure wind? Doppler Radar, Wind Vane
2. Identify the general char- Pressure Gradient: Drives winds from high to low pressure.
acteristics associated with
winds and pressure gradi- Coriolis Effect: Earth's rotation deflects wind direction.
ents
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.
3. Explain how temperature General Rule: Higher temperature, lower pressure; lower tempera-
affects air pressure near ture, higher pressure.
the ground and high up in
the sky when it warms up Warming Air:
or cools down 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.
4. What are the features of Land Breeze (Night):
land and sea breezes? Ex- Characteristics: Nighttime land cools faster, higher pressure over
plain the forces causing water, lower over land.
pressure differences and Forces: Breeze from sea to land.
how they make the wind
change directions Sea Breeze (Day):
Characteristics: Daytime land heats faster, higher pressure over land,

lower over sea.
Forces: Breeze from land to sea.
5. Identify examples of oth- Santa Ana Winds:
er types of local winds and
the general characteristics Hot, dry winds in SoCal, fall/winter.
of each 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.
6. Identify the characteristics Coriolis Force Characteristics:
associated with the Corio-
lis force 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.
7. What are the characteris- Cyclones in the Upper Atmosphere:
tics of cyclones and anticy-
clones in the upper atmos- -Pressure: Low-pressure systems.
phere? Include pressure, -Winds: Generally faster winds.
wind speed, and forces in- -Coriolis Force: Inward, causing convergence.
volved -Pressure Gradient Force: Outward, balancing Coriolis force.
