Understanding Weather Maps and Atmospheric Pressure

The video tutorial explains weather maps, focusing on isoline maps and isobars. It covers air pressure measurement in hectopascals and millibars, and describes high and low pressure systems. Weather fronts, including cold, warm, stationary, and occluded fronts, are detailed with their symbols. Wind conditions and the Coriolis effect are also discussed, highlighting how wind moves around pressure systems in different hemispheres.

What is another name for weather maps?

• Isobaric charts

• Pressure maps

• Topographic maps

• Synoptic charts

What unit is commonly used by meteorologists to measure atmospheric pressure?

• Pascal

• Bar

• Torr

• Hectopascal

On a weather map, what symbol represents areas of high pressure?

• P

• C

• H

• L

What type of weather is typically associated with low-pressure areas?

• Clear skies and little wind

• Rain, clouds, and high winds

• Sunny and dry

• Foggy and calm

Which type of front is represented by a blue line with triangles on a weather map?

• Occluded front

• Stationary front

• Cold front

• Warm front

What happens at a stationary front?

• Neither air mass moves

• Cold air overtakes warm air

• Warm air replaces cold air

• Cold air pushes warm air upwards

How is an occluded front represented on a weather map?

• Alternating red and blue line

• Purple line with triangles and semi-circles

• Blue line with triangles

• Red line with semi-circles

In which direction does wind flow around a low-pressure system in the northern hemisphere?

• Straight line

• Counter-clockwise

• Clockwise

• Zigzag

What effect causes wind to deflect to the right in the northern hemisphere?

• Thermal effect

• Coriolis effect

• Gravitational effect

• Magnetic effect

What does it indicate when isobars are close together on a weather map?

• Strong wind

• Weak wind

• Variable wind

• No wind
