Maritime and Marine Marine Weather and Meteorology 2

Question 1

What is a 'gale warning' issued by the National Weather Service?

Accepted Answer

Sustained winds of 34-47 knots forecast for marine waters

Answer

A Gale Warning is issued when sustained winds of 34-47 knots (39-54 mph) are expected in the forecast area.

Question 2

When thunderstorms are present, what is the safest action for a small boater?

Accepted Answer

Return to shore immediately and seek shelter away from water

Answer

Returning to shore is the safest option since thunderstorms pose lightning and severe wind risks; leaving the water eliminates exposure.

Question 3

What weather phenomenon is indicated by a ring around the sun or moon?

Accepted Answer

High cirrus clouds containing ice crystals, often preceding a warm front and rain within 24 hours

Answer

A halo around the sun or moon is caused by light refracting through ice crystals in high cirrus clouds, which often precede a weather front.

Question 4

What does NOAA's 'Zone Forecast' for coastal waters cover?

Accepted Answer

Winds, seas, and weather for specific ocean and coastal zones out to 100 miles offshore

Answer

Coastal zone forecasts cover conditions in specific marine zones out to approximately 100 nautical miles offshore including wind, wave height, and weather.

Question 5

What is the 'diurnal' sea breeze cycle in coastal areas?

Accepted Answer

Onshore breeze by day as land heats faster than water, offshore breeze at night as land cools faster

Answer

Land heats and cools faster than water; this creates onshore sea breezes during the day and offshore land breezes at night.
