RYA Day Skipper Weather and Meteorology

Question 1

In the UK Shipping Forecast, what does 'veering' mean when describing wind direction?

Accepted Answer

Wind direction changing clockwise (e.g., from south to west)

Answer

Veering describes a clockwise change in wind direction (e.g., from south to southwest to west). The opposite, a change anticlockwise, is called 'backing'.

Question 2

What is the Beaufort Scale used to measure?

Accepted Answer

Wind force, ranging from Force 0 (calm) to Force 12 (hurricane)

Answer

The Beaufort Scale classifies wind speed into forces from 0 (calm, less than 1 knot) to 12 (hurricane force, 64+ knots), with descriptions of sea state at each level.

Question 3

What weather conditions are typically associated with an approaching warm front?

Accepted Answer

Gradually lowering cloud, increasing rain, backing and increasing winds, and falling barometric pressure

Answer

An approaching warm front typically brings gradually lowering and thickening cloud (cirrus, then altostratus, then nimbostratus), steady rain, falling pressure, and backing winds.

Question 4

What does a rapidly falling barometer indicate to a sailor?

Accepted Answer

Deteriorating weather conditions with strong winds likely

Answer

A rapidly falling barometer indicates that a deep low-pressure system is approaching, bringing strong winds, rain, and potentially dangerous conditions. A fall of more than 10 mb in 3 hours is significant.

Question 5

In the UK Shipping Forecast, what visibility range does 'poor' indicate?

Accepted Answer

1,000 metres to 2 nautical miles

Answer

In the Shipping Forecast, 'poor' visibility means between 1,000 metres and 2 nautical miles. 'Fog' is less than 1,000m, 'moderate' is 2-5nm, and 'good' is greater than 5nm.
