Question 1

What does a rapidly falling barometer (more than 0.06 inches per hour) typically indicate?

Accepted Answer

An approaching storm or severe weather

Answer

A rapid barometric pressure drop indicates an approaching low-pressure system, which typically brings deteriorating weather and strong winds.

Question 2

A wind rotating counterclockwise in the Northern Hemisphere is associated with which type of pressure system?

Accepted Answer

Low pressure (cyclone)

Answer

In the Northern Hemisphere, winds rotate counterclockwise around a low-pressure (cyclonic) system due to the Coriolis effect.

Question 3

What type of fog forms when warm moist air moves over colder water?

Accepted Answer

Advection fog

Answer

Advection fog forms when warm, moist air is transported over a cooler sea surface, cooling the air to its dew point and causing condensation.

Question 4

The Beaufort Scale is used to measure what?

Accepted Answer

Wind force and speed

Answer

The Beaufort Scale is a numerical scale from 0 to 12 used to describe wind force and its effects on the sea surface.

Question 5

What is a 'small craft advisory' issued for?

Accepted Answer

Winds 15–33 knots or seas 5–7 feet

Answer

The National Weather Service issues a small craft advisory when winds are forecast between 15 and 33 knots or seas are 5 to 7 feet, posing hazards to small vessels.
