MET-O FINALS QUIZ 2

Which of the following is commonly found on a synoptic chart?

• Weather symbols and isobars

• Sea water temperature

• Seismic activity levels

• Tectonic plate boundaries

What do isobars represent on a weather map?

• Lines of equal wind speed

• Lines of equal atmospheric pressure

• Lines of equal sea temperature

• Lines of equal humidity

What does it indicate when isobars are closely spaced on a weather map?

• Strong winds

• Heavy Rainfall

• Calm weather

• High humidity

What type of weather is typically associated with a high pressure system?

• Cloudy with strong winds

• Clear skies and calm weather

• Stormy and rainy

• Snow and freezing temperatures

Why are weather fronts important for ship operations?

• They signal calm weather and safe sailing conditions

• They determine sea depth and tides

• They are major indicators of changing weather

• They show the direction of ocean currents

How is a warm front represented on a weather map?

• Green line with dashes

• Blue line with triangles

• Red line with semicircles

• Purple line with alternating triangles and semicircles

What type of weather is typically associated with an occluded front?

• Light drizzle and gradual warming

• Heavy rain, thunderstorms, and gusty winds

• Calm and clear conditions

• Snow and freezing fog

What is the main purpose of a prognostic chart?

• To predict changes in the atmosphere at a future time

• To measure humidity levels across different regions

• To show the present wind speed at sea

• To record past weather events

What does it mean when the isobars around a low-pressure system become tighter (closer together)?

• The temperature is rising

• The storm is intensifying (deepening low)

• The system is weakening

• Wind speeds are decreasing

How does wind direction typically change after the passage of a cold front in the Northern Hemisphere?

• Remains constant

• Shifts from southerly to northwesterly winds

• Shifts from north to east

• Shifts from east to south
