1In the Southern Hemisphere, how does wind circulate around a low-pressure system (cyclone) near the Earth's surface?

A.Clockwise and spiraling inward toward the center

B.Counter-clockwise and spiraling inward toward the center

C.Clockwise and spiraling outward from the center

D.Counter-clockwise and spiraling outward from the center

Explanation: In the Southern Hemisphere, the Coriolis force deflects moving air to the left. Around a low-pressure center, this causes air to flow in a clockwise direction, with surface friction causing it to spiral inward toward the low center (convergence).

2In the Southern Hemisphere, what is the direction of surface wind circulation around a high-pressure system (anticyclone)?

A.Clockwise and spiraling inward

B.Counter-clockwise and spiraling outward

C.Clockwise and spiraling outward

D.Counter-clockwise and spiraling inward

Explanation: In the Southern Hemisphere, air moves outward from a high-pressure system (divergence). Leftward Coriolis deflection causes this outward flow to circulate in a counter-clockwise direction.

3What is the standard temperature lapse rate in the troposphere defined by the International Standard Atmosphere (ISA)?

A.1.0°C per 1,000 feet (0.3°C per 100 meters)

B.1.98°C per 1,000 feet (6.5°C per 1,000 meters)

C.3.0°C per 1,000 feet (9.8°C per 1,000 meters)

D.0.5°C per 1,000 feet (1.6°C per 1,000 meters)

Explanation: The ISA standard temperature lapse rate in the troposphere up to 36,090 ft (11,000 m) is defined as 1.98°C (approx 2°C) per 1,000 feet, or 6.5°C per 1,000 meters.

4Which layer of the atmosphere contains almost all weather phenomena affecting aviation?

A.Stratosphere

B.Troposphere

C.Mesosphere

D.Thermosphere

Explanation: The troposphere contains approximately 75% of the atmosphere's mass and virtually all of its water vapor, making it the primary layer where clouds, precipitation, and weather systems occur.

5In a New Zealand METAR, what conditions must be simultaneously met for the code 'CAVOK' to be reported?

A.Visibility 10 km or more, no cloud below 5,000 ft or highest MSA, no CB or TCU, and no significant weather

B.Visibility 5 km or more, cloud ceiling above 3,000 ft, and no rain

C.Visibility 10 km or more, completely clear skies (0 oktas cloud), and winds under 10 knots

D.Visibility 8 km or more, no clouds below 1,000 ft, and no active thunderstorms within 20 NM

Explanation: CAVOK (Ceiling And Visibility OK) requires: visibility 10 km or more; no cloud below 5,000 ft AGL or below the highest minimum sector altitude (whichever is higher) and no CB/TCU at any height; and no weather of significance to aviation.

6When a cold front passes over New Zealand from the Tasman Sea, what is the typical surface wind direction shift?

A.From North-West to South-West

B.From South-West to North-West

C.From South-East to North-East

D.From East to North

Explanation: Ahead of a classic cold front approaching New Zealand from the Tasman Sea, winds are typically pre-frontal north-westerlies. Following front passage, the wind shifts to post-frontal south-westerlies accompanied by a drop in temperature.

7What altitude or height information is indicated on an altimeter set to the airfield QNH?

A.Height above the airfield datum elevation

B.Altitude above Mean Sea Level (AMSL)

C.Pressure altitude above the 1013.25 hPa datum

D.Density altitude corrected for non-standard temperature

Explanation: QNH is the altimeter subscale setting that causes the altimeter to read altitude above Mean Sea Level (AMSL). When on the ground at an airfield, it reads the airfield elevation.

8What does an altimeter set to standard pressure (1013.25 hPa) indicate?

A.Indicated altitude above mean sea level

B.True altitude above ground level

C.Pressure altitude

D.Density altitude

Explanation: When an altimeter subscale is set to 1013.25 hPa (29.92 inHg), it indicates Pressure Altitude, which is used for flight levels in controlled airspace above the transition altitude.

9In which temperature range is clear ice (glaze ice) most frequently encountered in convective clouds containing large supercooled water droplets?

A.0°C to -10°C

B.-10°C to -20°C

C.-20°C to -40°C

D.Below -40°C

Explanation: Clear ice (glaze) forms rapidly in clouds with high liquid water content and large supercooled water droplets, most commonly between 0°C and -10°C. The large drops flow back over the surface before freezing completely, forming a smooth, dense ice layer.

10Which type of airframe icing is characterized by a opaque, milky white, rough surface formed when small supercooled water droplets freeze instantaneously upon contact?

A.Clear ice (glaze)

B.Rime ice

C.Hoar frost

D.Freezing rain

Explanation: Rime ice forms when small supercooled water droplets (such as in stratiform clouds) freeze instantly on contact with the airframe, trapping air pockets between tiny ice particles to give an opaque, white, rough appearance.

CAA NZ CPL Meteorology Study Tips from Top Performers

1Understand Southern Hemisphere rotational directions: Lows (cyclones/troughs) rotate clockwise, while Highs (anticyclones) rotate counter-clockwise.

2Master local New Zealand weather patterns, such as the Canterbury Nor'wester Föhn wind effect, Cook Strait venturi funnelling, and Southern Alps mountain wave systems.

3Learn to distinguish structural icing types: Clear ice forms in high liquid water content at -0°C to -10°C; Rime ice forms in small droplets at -10°C to -20°C.

4Practice tephigram analysis to quickly identify stable, unstable, conditionally unstable layers and subsidence inversions.

5Be proficient in decoding all NZ weather codes including CAVOK, WS WRNG, SPECI, BECMG, TEMPO, and Volcanic Ash Advisories.
