Characteristics of High and Low Pressure

Watch the Ballooon Sound Effects video clip.

1

Is the pressure inside the balloon HIGH or LOW when the balloon IS inflated?

The pressure is equal inside and outside the balloon

The pressure inside the balloon is higher than outside the balloon

The pressure inside the balloon is lower than outside the balloon

1

When the balloon is released does the air flow out of the balloon or into the balloon?

Air flows out of the balloon when it is released

Air flows into the balloon when it is released

1

Knowing this, what is the correct direction that air flows

Air flows from Low pressure to High pressure in order to create an equilibrium

Air flows from High pressure to Low pressure in order to create an equilibrium

1

If the balloon was inflated to MAXIMUM capacity how would the air flow be affected?

The air flow (wind) would be slower coming out of the balloon

It would have no affect on the air flow (wind)

The air flow (wind) would be faster coming out of the balloon

1

When a balloon is blown up to MAXIMUM capacity the pressure inside the balloon is __________ compared to the outside air

The Same

Very Low

Very High

1

Based on the two previous question, when there is a BIG difference in pressure between to locations you would expect:

High winds

Gentle winds

No winds

Wind ALWAYS blows from areas of HIGH pressure to areas of LOW pressure. The BIGGER the pressure difference the FASTER the wind will blow.

1

Pressure differences are shown on a weather map using ISOBARS. ISOBARS represent lines of EQUAL PRESSURE. On this map you can see where the (H) highest pressure and (L) lowest pressure on the map are located. Wind will travel from the H to the L. The CLOSER that the ISOBARS are together the BIGGER the pressure difference. Where would the FASTEST winds be blowing on this day?

In Canada

On the West Coast

In the Central part of the country

On the East Coast

You are on a BOAT travelling off of the coast of North Carolina during this storm. Based on the weather map above the safest route around this storm would be:

Travel North of the storm because this is where the wind will be most gentle

Travel East of the storm because this is where the wind will be most gentle

Travel South of the storm because this is where the wind will be most gentle

Please watch the 40 second video above in order to answer the following questions

1

In this video clip what is the correct movement of the ball?

A to B

B to A

1

Why would LOCATION A represent an area of HIGH PRESSURE?

Air travels from HIGH pressure to LOW pressure

Air travels from LOW pressure to HIGH pressure

1

Why did the ball curve to the right as it was traveling AWAY from Location A?

Due to the spin on the ball

Due to the spin (rotation) of the earth

The wind carried it that way

null

IMAGE ABOVE IS LOOKING DOWN AS IF IT WERE A MAP

List below describes the air flow at labelled locations on the diagram above

1. Wind flows FROM High pressure TOWARDS Low pressure and veers to the RIGHT as Earth rotates beneath it.

2. Winds flows CLOCKWISE around HIGH pressure

3. Wind flows AWAY from High pressure towards Low pressure in order to create equilibrium.

4. Winds gets sucked INTO LOW pressure just like pet hair into a vacuum.

5. Winds travel COUNTERCLOCKWISE and up the center of Low pressure just like a tornado.

Above is a sideview that shows the CONSTANT VERTICAL air motion as well as the wind direction.

1

What direction does wind flow around a HIGH pressure system?

Clockwise and towards the center

Clockwise and away from the center

Counterclockwise and towards the center

Counterclockwise and away from the center

The video above was a very close encounter with a deadly tornado. Notice the direction that the wind flows around the center of the tornado. A tornado is a very violent Low pressure system.

1

What direction does wind flow around a tornado which is also an intense LOW pressure system?

Clockwise and away from the center

Counterclockwise and away from the center

Counterclockwise and towards the center

Clockwise and towards the center

1

Which statement is correct?

Winds ALWAYS flows UP at the center of LOW pressure systems

Wind ALWAYS flows DOWN the center of LOW pressure systems

Winds flows UP or DOWN LOW pressure systems depending on the flow of wind at the surface

Wind flows up LOW pressure systems during the day and reverses at night

1

A LOW pressure system would be be compared to:

A leaf blower

A vacuum

A fire pit

A block of ice

Using thick black arrows, draw the correct pattern that the wind traveled from the center of High pressure towards the center of Hurricane Sandy on October 29, 2012 as it approached the Jersey Shore.

Characteristics of High and Low Pressure

Is the pressure inside the balloon HIGH or LOW when the balloon IS inflated?

When the balloon is released does the air flow out of the balloon or into the balloon?

Knowing this, what is the correct direction that air flows

If the balloon was inflated to MAXIMUM capacity how would the air flow be affected?

When a balloon is blown up to MAXIMUM capacity the pressure inside the balloon is __________ compared to the outside air
