Maritime Meteorology Quiz

Atmospheric Science

• Variations in air pressure across different regions are caused by Earth's rotation.
• Humidity is associated with the formation of clouds.

Meteorology in Maritime Studies

• The primary purpose of meteorology in maritime studies is to facilitate safe navigation.
• Meteorology plays a crucial role in mitigating weather-related risks to ensure safe maritime voyages.

Weather Measurement Instruments

• A ceilometer measures cloud base height above the ground.
• An anemometer measures wind speed.
• A hygrometer measures humidity.
• A barometer is essential for predicting weather changes.
• An altimeter is primarily used for navigation during foggy conditions.
• A barograph measures air pressure variations over time.

Clouds and Weather Phenomena

• Dew point is the temperature at which air becomes saturated with moisture.
• Cumulus clouds are associated with fair weather.
• Stratus clouds are low-level clouds that often bring steady rain.
• Cirrus clouds are thin and wispy, often appearing high in the sky.
• Cumulonimbus clouds are associated with thunderstorms.
• Nimbostratus clouds are often gray and bring continuous rain or snow.
• Deposition is the process of water vapor changing directly to ice crystals.
• Fog is a type of cloud that forms near the ground.

Fronts and Air Masses

• A front is a boundary separating two masses of air of different densities.
• An air mass is a large body of air that has similar temperature and moisture properties throughout.
• A depression or low-pressure system is a region of low atmospheric pressure.
• When a cold front meets a warm front, the cold air mass moves under the warm air mass.
