Understanding Atmospheric Pressure and Wind Patterns

What type of weather is typically associated with high-pressure systems?

• Cloudy and rainy

• Dry and descending air

• Warm and humid

• Cold and stormy

What creates small areas of local circulation called convective currents?

• Uneven heating of the air

• High-pressure systems

• Low-pressure systems

• Coriolis force

What is the effect of plowed ground, rocks, and sand on solar energy?

• They reflect solar energy

• They absorb solar energy quickly

• They cool down the air

• They create high-pressure areas

What is the effect of vegetation on solar energy?

• It reflects solar energy

• It absorbs heat slowly

• It creates low-pressure areas

• It increases air pressure

What can convective currents close to the ground affect?

• The speed of the aircraft

• The pilot's ability to control the aircraft

• The altitude of the aircraft

• The fuel efficiency of the aircraft

What is the effect of wind on the leeward side of a mountain?

• Smooth flow

• Increased turbulence

• Decreased speed

• Clear skies

What is the primary factor affecting turbulence associated with ground obstructions?

• The color of the aircraft

• The primary velocity of the wind

• The type of fuel used

• The number of passengers

Why is low-level wind shear especially hazardous?

• A) It occurs only at high altitudes

• B) It is associated with clear weather

• C) It is due to the proximity of an aircraft to the ground

• D) It only affects small aircraft

What is a microburst?

• A) A large-scale weather system

• B) A small, intense downdraft

• C) A type of hurricane

• D) A gentle breeze

What is the purpose of the LLWAS-NE, TDWR, and ASR-9 WSP systems?

• A) To detect hurricanes

• B) To alert pilots of microbursts

• C) To measure temperature

• D) To track bird migrations
